Royalty comes in a few forms. There are the royal families of the world. There’s rock royalty like Angus Young, movie royalty like Meryl Streep. Then there are motorsport royalty names like Brabham. Australia’s own Sir Jack created a special place in history with his bespoke Grand Prix cars and the engineering prowess. Now, in 2018, the Brabham name has been thrust back into prominence with the release of a car and a company bearing the famous name. Brabham Automotive, with David Brabham, son of Sir Jack Brabham, at the helm have released earlier this year the Brabham BT62. BT continues a small yet very significant part of the Brabham history. Sir Jack Brabham and Ron Tauranac made up the BT part of the names given to the race cars built starting with the BT1 from 1961. The BT62 is a purpose built track weapon with none of the cars to be built destined, currently, to see road work. There’s some astonishing figures that come with the sleek, aerodynamically tuned design. Weight is just 972 kilograms and the car is powered by a bespoke 5.4-L V8 that produces 522kW. Torque? Plenty, thank you, at a hefty 667Nm. A race spec exhaust is naturally fitted and has been tested to produce a 98 decibel noise limit. The fuel tank holds 125-L and fuel is entered via race spec connectors. Hi-po cars also need downforce and the exterior design of the BT62 has plenty. In this case there is more downforce than the weight of the car, at 1200 kilograms. That last figure is more important than the face value suggests. Brabham Automotive are only building seventy, and they’re all intended to be track-based weapons. And with weight being the enemy of racing cars, that 972 kilograms comes courtesy of carbon fibre body panels, including the canards, front aeroblades and splitter, the dual element rear wing and diffuser, and the floor. Race tech is in the form of a dry sump lubrication system, Motec engine control, and a fly by wire throttle system. An air jack system for quick lift and wheel change is also fitted. More Australian royalty in the form of a Hollinger six speed sequential transmission that has an engine “blip” on downshift can be found underneath the svelte bodywork, plus bespoke paddle shifts. Being a track day oriented machine also means some basics need to be fitted. A FIA approved safety master-switch is coupled with a race spec 12 inch digital screen complete with GPS tracking and timing. Ride and handling comes courtesy of double wishbones front and rear that hold push-rod Ohlins TTX dampers and coil-over shocks. The BT62 incorporates Brabham components to add extra Brabham DNA. Centre lock race wheels from Brabham are wrapped in 11J x 18 rubber up front, 13J x 18 at the rear. Brembo supply the stoppers with carbon pads on carbon discs, with 380mm and 355m front and rear. The suspension has Brabham’s own Combined Bump Limiter, which minimizes front and rear yaw action. Brabham also fit their own steering wheel made from carbon fibre with the driver ensconced in a Brabham seat.

Classic Australian Touring Cars

Brand loyalty. It’s a “thing” that companies spend a lot of money on in research and making it happening. Perhaps the best example of this is in the world of cars and there’s nothing more stronger nor more divisive than the love a man hath for the brand of car. That’s why any list of Australia’s top touring cars will always be subjective, sure to cause discussion, and will be debated at length. Agreed, there are the drivers and team to consider but tell that to the marketing teams. 1. Ford Falcon XY GT-HO Phase III 1971 and Bathurst see this car linked permanently in our motorsport history. Lap 43 of The Great Race saw Bill Brown and his yellow XY roll along the Armco after his front right tyre blew at over 100mph coming into McPhillamy Park. Three and a half rolls later Brown and his XY became part of folklore. Though it wasn’t the first time Bill had put a GT-HO on its lid, but that is a story for another day. However there is the car itself. In qualifying for 1971’s race the top seven grid spots would be occupied by this racing machine from the Blue Oval factory. The top two cars were factory backed, the other five from privateers, and just 1.1 seconds separated fourth through to seven. Pole sitter Allan Moffat would take pole by three seconds ahead of John French. Moffat and his Ford Falcon XY GT-HO Phase III would go on to win the 1971 Hardie-Ferodo 500 and would fill in five of the top ten positions at race finish. 2. TWR Jaguar XJ-S Jaguar is one of those brands that is either a love, or it’s a ummm, no thanks. And whilst it may not instantly be recognized as a classic Australian touring car, it did win a Bathurst 1000. The Jaguar’s Bathurst story started when Tom Walkinshaw Racing took the long and elegantly designed V12 from one of Britain’s oldest brands, and turned a grand touring car into a race oriented touring car. The car itself took over from the legendary E-Type in 1975 and in racing trim would be entered into the then Group C category. This was for cars with engines of over three litres in capacity and placed the near five metre long “Jag” against Holden’s VK Commodore with a 5.0L V8. In the hands of TWR and Tom himself, three XJ-S machines would be in the top ten for the 1985 James Hardie 1000. Entitled “Hardies Heroes” grid spots 6, 2, and 1 would have the JRA Ltd backed cars in place. John Goss piloted the number 10 badged car for sixth in the shootout, with Jeff Allam and Walkinshaw himself taking second and pole. Come race time and it was the German/Australian pairing of Armin Hahne and John Goss that would greet the chequered flag after 163 laps and a race time of six hours forty one minutes. Goss would also set the fastest lap with a 2:21.86. 3. Holden LX Torana SS A9X Hatchback. Regarded as possibly one of the prettiest yet aggressive looking cars on Australian roads, the Holden Torana hatchback of the mid 1970s would be powered by a choice of six and V8 engines. With the tag of A9X giving the car a stronger differential and rear disc brakes plus slightly modified suspension and a Borg-Warner T10 manual four speed transmission. Powered by the L34 spec 5.0L V8, Holden entered the LX into the Class A category for the 1978 Hardie-Ferodo 1000. That years was the introduction of the Hardies Heroes shootout, where drivers literally would draw the top ten running order for qualifying from a hat. This era was also the sweet-spot for the Holden v Ford rivalry, as the top ten would see six Holdens and four Ford XC Falcon hardtops. Driven by Peter Brock, it would be the Marlboro-HDT Torana that would take pole by 8/10ths ahead of the Moffat Ford Dealers pairing of Colin Bond, a long time friend of Brock, and Allan Moffat. History shows that the Holden LX Torana SS A9X Hatchback would fill four of the top ten finishing positions, with another two being the A9X four door versions. Brock and co-driver Jim Richards would be the only car to complete the full 163 laps, finishing a full lap ahead of another A9X hatchback driven by Allan Grice and John Leffler. And then there was the legendary performance at Mount Panorama in 1979, where Brock and Richards would finish a staggering 6-laps ahead of everyone else – the next seven placed cars were also A9X Toranas. 4. Ford Falcon XC GS Hardtop Ford Australia had resurrected a two door design for its legendary Falcon nameplate with the “coke bottle” XA Falcon in 1972. A slender nose would be offset by a somewhat heavy tail, with the rear flanks seemingly overwhelming the 14 inch diameter wheels. Subsequent redesigns would see subtle changes at the rear and with the blunter XB and XC noses adding an assertive presence. Although perhaps of itself not a car that imprints itself into racing consciousness, it was the 1977 one-two finish of the big machines that has the XC Falcon two-doors in this list of classic Aussie touring cars. Although Allan Moffat, the Canadian born driver that had made Australia his home, had qualified third, behind team mate Colin Bond, he would subsequently lay down the quickest lap of the 1977 race. Finishing a lap ahead of Peter Janson and Larry Perkins in their A9X hatchback, team orders had Moffat lead Bond into the final turn and across the line by a half car length in vision that brings tears to the eyes of Ford fans. 5. Volkswagen Beetle 1200. 1963 and the Volkswagen Beetle is finding love and homes throughout the world. It also found success on Australian racetracks. Entered into Class A, a category for cars costing less than nine hundred pounds, the “Dak-dak” would be amongst the list of cars racing at Mount Panorama for the Armstrong 500. The race had moved from Victoria’s Phillip Island and with the Australian Racing Drivers Club the new organizers. In Class A, four VW 1200s would be in the top 5, with the winners of the class, Barry Ferguson and Bill Ford completing 116 laps of the new venue, and completing this list of the top five Australian Touring Cars.

Classic Bathurst Recap - 1989

Changes were in the wind in the 1989 Bathurst 1000. Sponsored by beer giant Tooheys, the event continued its growth in stature internationally, and internally. Teams expanded from one car to two, and a return to the past was made, in the form of a standing start. The all-conquering Ford Sierra RS500 was back and in bigger numbers. Enough were here that one of Australia’s favourite sons and a Holden icon had made the jump into the Blue Oval camp. The King of the Mountain would also be involved in an incident that, although technically within the rules, wasn’t seen as being of a sporting nature. The Sierras attracted big names from overseas. Briton Andy Rouse came in to drive alongside Peter Brock. Ruedi Eggenberger returned to run the Allan Moffat operation, with a brand new car for Klaus Niedzwiedz, Moffat and Frank Biela. Alain Ferté flew in to drive a Glenn Seton car. Toyota was here, with the six cylinder Supra. John Smith and Drew Price, while Nissan had Anders Olofsson. This year’s race was also an advance in television coverage, with the Tooheys Top ten shootout broadcast in full for the first time. The fastest ten cars from qualifying on Friday were sent out on the Saturday to determine the positions. Of the top ten final results, all but one were Sierras, with Nissan and Jim Richards claiming seventh. Peter Brock would be given pole and it would be the only pole position of his career that wasn’t in a Commodore powered by a V8. It would also be a frustrating result for the Holden faithful as there were no Red Lion cars to be seen in that ten. There is also a little bit of history here, with all cars in the top ten being powered by a turbocharged engine, a feat not seen before or since. The controversy around Brock and his car was simple, in essence. A fire suppressant system in the cars used a gas called Halon. A nozzle in the engine bay after the top ten run was found in scrutineering to have been pointed towards the engine’s turbo intercooler. The theory was that the gas had been discharged, lowering the temperature and boosting the engine output. Although later deemed to be not illegal, Brock was fined five thousand dollars. A return to the standing start procedure also raised eyebrows. With a set start time of 10:00am, a formation lap had been performed and cars lined up on the grid. However it appeared that some were a little early and the subsequent wait may have contributed to a number of cars suffering engine failures during the race. Race start and Brock lead the field, with old mate and sparring partner Dick Johnson, (with co-driver being Rare Spares ambassador John Bowe) in hot pursuit. There would be drama for Andrew Miedecke inside the first lap, with his #6 Sierra stuck in fifth gear thanks to a broken gear selector. This came on top of the #8 sister car, driven by Andrew Bagnall, crashing during the top ten shootout, however with only light damage allowing the car to start as the tenth car. Coming down Conrod Straight, Johnson’s Sierra would pass Brock to take the lead, where throughout the next 160 laps it would remain. The race would see a number of cars fail to finish due to mechanical problems. Brock himself would pit his Sierra, complaining of a loose rear wheel. The Tony Longhurst and Giancarlo Brancatelli Sierras would retire with Brancatelli’s car losing a wheel, and Longhurst out after his Benson and Hedges #25 car blew a head gasket. Longhurst would move into the #20 car and along with Alan Jones and Denny Hulme completed the race in fifth. Glenn Seton’s Sierra had found oil on the track at Skyline. Seton’s #30 Peter Jackson sponsored car slammed into the tyre barrier backwards. Seton was ok and the car was able to be driven to the pits for repair where he, John Goss, and Tony Noske would later pilot the car to 20th. The #35 car would not complete the race. Debris from Seton’s vehicle had an unfortunate knock-on effect for Brad Jones. Brake lines are an effective piece of equipment in a car when they’re in one piece. Jones’ car would have theirs cut by the debris, leaving Jones to find that out at speed coming into the Chase. He and co-drive Paul Radisich benched the car and would lose eight laps, finishing 9th. The Sierras were showing signs of stress with the #18 Shell Ultra Hi car, driven by the UK pairing Jeff Allam and Robb Gravett, suffering electrical issues. Allan Moffat’s second car would be parked after just thirty laps, whilst John Mann and Murray Carter’s Sierra lasted just ten. However the Skylines and Commodores were showing no such signs. Alan grice and Peter Janson would find themselves in the top five thanks to smart fuel pit strategy however some gremlins got into the transmission, dropping them to tenth at race finish. Brock’s rear wheel issue looked to have been fixed and the team would be back in the top three half way through the race. But again a problem occurred, this time with a recalcitrant wheel nut needing to be cut off. The hub was discovered to be so worn a new one could not be fitted and the team was out. Bowe and Johnson had cemented their lead but in the closing laps the turbo boost pressure was falling. Bowe nursed the car along enough to hold the lead, watching the second Moffat Sierra, driven by Niedzwiedz and Frank Biela eventually fall off enough for Bowe to pit for a final fuel stop and get the car across the line for the win a full minute ahead of Biela. Third would go to Jim Richards and a young Mark Skaife, in the Nissan Skyline HR31 GTS-R, with a team driver swap having Anders Olofsson bring home the second car in fourth. Of fifty six cars entered, twenty nine would not see the chequered flag for the Tooheys Bathurst 1000 in 1989.

Classic Bathurst Recap - 2006

The Bathurst 1000 of 2006 will be forever etched in history as the one “The King of the Mountain” watched from up high and saw his protégé’ Craig Lowndes, alongside a champion in the making, Jamie Whincup, hold the first ever Peter Brock Trophy over the pit lane crowd. It was the second win for CL, as he’s known, and the first for Whincup after his second place the year before. Thirty one cars would be entered in this year’s “Great Race”, with an almost even split of Holden and Ford branded vehicles. Ford would field fifteen BA Falcons, the first model after the ill-fated AU Falcon, whilst Holden showcased sixteen VZ Commodores, the final iteration of a design essentially a decade old. Qualifying was tight and intense, resulting in the top eight cars being separated by under a second, and the top eighteen cars separated by under two seconds. Again it was almost an even split for the then top two locally made cars, with four Falcons and six Commodores. Of the top five though, just one blue oval branded car would be there, with a former Holden driver, Jason Bright, in second. Provisonal pole had gone to Holden driver Mark Skaife in a blistering 2:06.9764, just a tenth ahead of Bright’s Falcon. The Top Ten Shootout would see Skaife carry that form onwards, with a 2:07.4221, a full three tenths quicker than Bright. Rick Kelly, New Zealand born Jason Richards and Greg Murphy, all in Commodores, would round out the top five. Eventual race winner Lowndes, driving the Ford BA Falcon, would be beaten to fifth by a mere four one thousandths of a second. The race itself was held on Sunday October 8. In 2006 it was the ninth race weekend of the then V8 Supercars Championship. It would also prove to be the longest race since 2002. With all 161 laps completed it finished just seven seconds shy of seven hours and a full twenty two minutes longer than the previous year. A race start incident proved to be crucial in the final results. Pole sitter Skaife went from hero to zero within a half minute, with a clutch failure leaving him battling to get his Commodore moving to race speed. Although he had cleared the first corner he had got as far as the first rise on the road to the top of the mountain, and with heavy traffic behind him an unfortunate Jack Perkins was blindsided, ploughing his Commodore into Skaife’s and forcing him into the wall. This allowed the second grid spot driver, Jason Bright and his co-driver Mark Winterbottom, to take the lead. However a brake lockup had Bright require a tyre change with just fifteen laps completed. More woe befell the duo with Winterbottom garaging the car on lap 28. A full fourteen cars would fail to finish the 2006 race, with Rare Spares ambassador John Bowe, alongside his mate and co-driver Brad Jones, finishing eleventh. The race was punctuated by a number of safety car interventions, including one of over twenty minutes after the veteran Kiwi born Paul Radisich, on lap 71, had his Commodore spear into a retaining wall at the Chase. The impact rolled the car onto its side and left Radisich in need of trackside marshal intervention to remove him from his stricken vehicle. Just six laps would be held in that fourth hour of the race. As seems traditional with the Bathurst 1000, a late race incident played a part in the final standings. Jason Richards also lost control and hit a wall. Laps remaining were just ten. Rick Kelly and Craig Lowndes were dealing with a six second buffer prior to the final safety car call to deal with the Richards car. A fired up Lowndes would lay down the race’s quickest lap on the 158th circuit of the 6.213 kilometres worth of tarmac, and would greet the chequered flag a bare half second ahead of a determined Kelly. In tumultuous and emotional scenes on the presentation balcony, Lowndes would be in tears as he acknowledged his late friend and mentor, Peter Brock. Is 2006 your favourite Bathurst 1000?

Rare Spares – Commodore Goes International.

27. August 2018 10:07 by Rare Spares in General, Rare Spares  //  Tags:   //   Comments (0)
It’s almost an ice to Eskimos and coal to Newcastle situation. Holden, the isolated arm of General Motors, was once a huge exporter of Aussie built cars, and that includes the Commodore. It was built here in Australia and sold in the U.S. under the Pontiac G8 and Chevrolet SS labels, with the latter bringing a wry smile to those that decried the Chev badge on a Commodore in Australia. Finally, a Commodore that left the factory with the bowtie badge fitted! The cars were largely the same as those seen “down under” with the obvious noticeable exception being the switch to left hand drive. The Pontiac G8, based on the Holden VE Commodore, was sold there over the 2008-2009 model years. Pontiac as a brand was discontinued by GM in 2009 however, leaving Holden and GM in a bind as to what could be supplied. The G8 featured a larger and more muscular looking twin nostril front end than the VE Commodore and a redesigned lower front bumper section. The G8 was initially released as the G8 with a 3.6L V6 before the GT and GXP, packing a 6.0L and 6.2L V8 respectively. The GXP was loaded with the sporty FE3 suspension package, leather interior, and a six speed manual transmission that was originally slated to be in the GT. The GT itself featured cosmetics such as a quad exhaust rear end and clear tail light lenses, an 11 speaker sound system from Blaupunkt in Germany, and offered options such as 19 inch wheels. Holden had a history with Pontiac going back to the early noughties. The GTO, a rebadged and rebodied Monaro made its debut there in 2004. Unfortunately, the GTO didn’t sell well in the American market – they didn’t take to the Australian built GTO like they had in the past for the American built versions. The Commodore also sold as the Chevrolet Lumina SS in the Middle East and the Vauxhall Monaro in the UK, it was powered by the 5.7L/350cid V8 found in the Corvette of the day. Pontiac’s history was evident with the familiar large twin nostril design before an addition in 2005 had an extra pair on intakes fitted to the bonnet. The final model in 2006 came with a 300kW 6.0L engine. Holden also shipped the ute and Caprice to the U.S. The Caprice formed the basis for a vehicle used in various police forces whilst the ute was marketed as a sports truck, the G8 ST. The Caprice was so popular with the American police force that an exclusive PPV (Police Patrol Vehicle) version as built. It featured a unique column shift automatic transmission – which was not used on any other model in the range. It was not available to the public, and could only be ordered for Police use. The export program was quite successful for Holden, with revenue of $1.3billion reported in 2006. Despite the success for Holden in Australia, General Motors in the USA decided to park the Pontiac brand, after more than 80 years history with the nameplate. The demise of Pontiac also left Holden in Australia with a lot of spare parts that were no longer required. To utilise the Pontiac spares, Holden introduced an optional no-cost package on the series 2 VE Commodore SSV featuring the Pontiac G8 style nose and style. After Pontiac was benched, GM re-introduced the Commodore as the Chevrolet SS. This was based on Holden’s VF platform. Sold from late 2013 until the program was cancelled in 2017, just shy of 12,900 cars were sold. The SS sold in the U.S.  powered by the LS3 V8 that punched out 309kW and 563Nm. Standard transmission was a paddle shift fitted six speed auto. Holden’s engineering team had stiffened the chassis, rejigged the suspension settings, and improved the safety factor by re-engineering the steels used. The redesigned chassis rails combined with electronic items such as Blind Spot Detection, Lane Departure Warning, and a better electrical system. What are your thoughts on the export program? Did you buy one of the Commodores that was released with the Pontiac body add-ons? Let us know via the comments section or on our Facebook page.

The Holden Monaro 427C - Australia's Homegrown GT Monster

The Australian automotive industry is an oddity in the global scheme of things. A small buying population, the most brands per head of population, and innovations not seen elsewhere, make it virtually unique. Although we weren’t the first to build a car with a hardtop and two doors, we certainly made some great ones. Ford, Chrysler, Mitsubishi, and Holden all have cars that are memorable and one that stands out was the Monaro 427C.  Designed, engineered, and built in Australia, this car was intended to be a track weapon and race in the Bathurst 24 Hour. The first of these races was set to run in late 2002, meaning the development of the car, slated to run in 2003, had to be brought forward.  The heartbeat of the 427C was its US sourced 7.0L or 427cid V8. With the Holden Racing Team turning down the offer of developing the machine, Garry Rogers Motorsport (GRM) took the Chevrolet Corvette C5-R engine, a Monaro body, and the responsibility of running the 427C as a race car.  The car would later be a controversial one; the race would attract cars from outside Australia such as Lamborghini’s Diablo GTR, Ferrari’s 360 N-GT, and the monstrous Chrysler Viper ACR. All of these cars would race with the same engine they would come off the production line with. However, the Monaro at the time came with Chev’s fabled 350cid or 5.7L V8, and therefore would be ineligible to run. However, the organiser of the race, which would come under the umbrella of a racing group called Procar, allowed the Monaro to be run with the bigger engine to be seen as more competitive with capacities such as the 8.0L V10 in the Viper. As the race was going to be run under the then current GT regulations, GRM had to design a body kit to suit both the regulations and the aerodynamics of the VX Commodore based two door. Using the V8 Supercars design as a basis, GRM fitted a wider rear wing that sat below the car’s roofline, as per the regulations. A similar front air dam was fitted to the front, and underneath the 427C utilized a number of components that could be found on a Supercar.  A technically minded casual observer would see a Hollinger six speed manual transmission, wheels of 18 x 11 and 18 x 13 inches, MacPherson strut front suspension and a trailing arm rear, bolted to coil springs and thick anti-roll bars. The engine was said to be good for 600 ponies (447kW) and would be bolted into the front of a car weighing 1,400 kilograms.  All up the Monaro 427C would be 4789mm in length, run a front and rear track of 1559mm/1577mm, and roll on a wheelbase of 2788mm. The aero package provided plenty of down-force and made for a stable on track racer.  Raced at the 2002 Bathurst 24 Hour by a team of four drivers, being Garth Tander, Nathan Pretty, Steven Richards, and Cameron McConville, the car was also being touted as being available as a road car. The race car itself would prove to be strong, durable, and a race winner. Although despite suffering a flat tyre and a collision with another car, the car would ultimately win in its debut race by 24 laps. As a road car, it was potentially to be powered by a 433kW version of the 427cid engine. But, as a business case, the numbers simply didn’t add up and would result in a mooted buy price of $215,000 being out of reach of its intended market. Just two road going cars, and just four race cars, would be built. The Monaro 427C would go on to compete in the Australian Nations Cup Championship in 2003, and the Bathurst 24 Hour race in the same year. A second race car had been built by then. Driven by Peter Brock, Jason Bright, Todd Kelly, and Greg Murphy, the car would win by just 0.3035 of a second. Tander, driving the 2002 winning vehicle, was thwarted in a last sector charge by a yellow flag thanks to a car close to the racing line. The 427C would race in 2004 and see a third chassis completed, before the Nations Cup category collapsed due to fiscal issues. With regulations reverting to GT Championship rules in 2005, the Monaro 427C was deemed ineligible. Of the race cars, one is with a private collector, one is in the Bathurst Motor Museum, and little if anything is known of the locations of the others.  

A Brief History of Cheating in Motorsports

Human nature is one of the most diverse things we see on planet earth. Sadly, not all of human nature is benign, good, warm, welcoming. One of the negatives we exhibit is called cheating. Be it at school, on our partner, at work, it’s an undesirable trait. But in motorsport? Yes, it happens. All too often. And it happens worldwide. It happens in rallying. It happens in Formula 1. It happens in IndyCar. It happened here in Australia. America’s NASCAR was full of innovative people. At one time they had specified a maximum size for the fuel tank. A “clever” interpretation of the rules has Smokey Yunick fit a fuel hose that was eleven feet long and two inches thick. As a result, his car’s overall fuel capacity was increased. Ynick also sidestepped the rules by having an oversized tank fitted but with an inflated basketball inside. This allowed the tank to be filled to more than the regulated amount once the ball was deflated. Tim Flock decided on a different way to improve the fuel economy of his NASCAR. His steel roll cage wasn’t steel. It looked like steel, but close inspection had a wooden structure smartly painted to resemble steel. Australia’s royal motorsport name was involved in a somewhat cheeky cheat in 1981. Fabled F1 designer Gordon Murray built a car for the Brabham team that had adjustable ride height. When cars are scrutineered there’s a set ride height they have to adhere to. Murray built in a system that would lower the car under that ride height but would raise it back to the required amount when stopped. Murray’s sense of humour was brought into play by having a box with leads that would attach to the car, for no reason other than to visually distract onlookers, placed at random locations on the car when stopped. Another entry from NASCAR with Ken Schrader finding his tyre wear exceeding the ability of the car to deal with it. Although leading a race, the second place car was closing rapidly. A quick thinking Schrader discharged his fire suppressant system and the second car’s driver, thinking Schrader’s car engine was about to explode, backed off. The canny Schrader timed this well enough for his lead to get him over the line for a win, with his car in perfect working order. Japanese goliath Toyota dominated the world rally scene with its awesome and aggressive looking all wheel drive Celica. Complete with huge rear wing, quad headlight front, and legal turbocharger…wait, did I say legal turbocharger? 1995 and the car is dominating the rally world. The WRC had stated a maximum horsepower output of 300. Toyota had abided by the rules that stated a restrictor plate must be fitted inside the turbo. What they also interpreted was that the regulations said nothing about the restrictor plate having to stay in one spot. Some brilliant engineering had the plate being moved by springs that allowed extra power to be generated, with an estimated fifty extra horsepower. The design of the turbo was such that a thorough pull-down of it was required to see the plate and even then this appeared almost as it should be. Australia’s great race, the Bathurst 1000, closes out this quick look at motorsport cheating. The 1987 race was won by the stove hot Ford Sierras. Factory supported they were quick, at times almost undriveable according to Rare Spares ambassador John Bowe, but a little bit of physics came in to play for the win. Larger tyres cover more distance for little extra effort and the first two cars, both from the same team, were found to have enlarged wheel arches at the front, allowing a bigger rolling diameter tyre. Subsequent investigation and appeals against the team had them disqualified, handing the win to the third placed team. That team was from HDT and the car was driven by David Parsons, Peter McLeod, and one Peter James Brock. The win, under less than ideal circumstances, gave the great PB his ninth and ultimately final ATCC win at The Mountain. Do you know any ingenious tales of people skirting the rules in motorsports?

The Ford Barra Engine. A Modern Classic?

Grandpa’s axe. It’s a term usually employed to describe something that’s been around for decades and is almost unbreakable. And when it does break it’s repaired in a low tech way. Simplicity rules, you see. Ford’s venerable straight six engine was Australia’s automotive equivalent of that axe from grandpa’s shed. Covering a range of capacities including the famous 4.1L or 250cid, its no nonsense, take what it was given, unburstable design, has it as a favourite in Australia’s car loving hearts. The straight six that Australia saw was born in America. Available in various capacities there, including a 200cid six that was seen in the original US Mustang, Ford’s Australian arm unveiled the 250cid straight six in 1970. Its basic design was strong, simple, just like grandpa’s axe. A 2V suffix was given to the engine, denoting that the carbie had two venturi and would breathe deeper than the single carbied versions. Available from the XY through to XB Falcon, it was good for 116kW and 325Nm, a hefty increase over the standard 200cid’s 96kW/257Nm delivery. Barra itself is a contraction of Barramundi. That’s not just a tenacious fish, it was the code name for the engine during development. It was applied not only to the straight six but also to the three valve 5.4L V8 version. The six was built from 2002 and was found in various Ford products such as the Falcon and Territory until Ford Australia ceased manufacturing in 2016. The V8s, in Barra then Boss and Coyote form, were there until the FG-X model of the Falcon and derivatives wrapped in 2016. The Barra V8 ceased with the BF Fairlane which was available from 2005 to 2007, and became the last Fairlane model produced here.   The straight six was engineered into several different versions including a LPG fed engine. But many “revheads” would say the six’s finest hour was when it was built with a turbocharger and bolted into the XR6, F6, and suchlike. With “normal” engines pumping out an original 182kW, 190kW, and 195kW, with 380Nm, 383Nm, and 391Nm, the turbo took the power and torque to world class levels. There was an initial offering, of 240kW and 450Nm, with that twist available from 2000 to 4500 rpm. Along came the 245kW and 480Nm version before the Barra 270T, with Garrett GT3576R turbo, and Barra 310T showed what clever Australian engineering could deliver. Found in the BA, the BF, and then the FG, the big six may have actually undersold its capabilities. Rumours abound that in order to continue sales of the V8, the power and torque figures were deliberately quoted as being less than what they actually produced, with 360kW and 700Nm being whispered as the true figures. Ford’s best six came in the form of the Barra 325T. This, sadly, was a deliberately limited run and sold in the limited edition FG-X XR6 Sprint. With ten pre-production vehicles, five hundred for Australia, and just fifty for New Zealand, it was a special engine in a special car. Power was quoted as 325kW @ 6000rpm, and 576Nm at a driver friendly 2750rpm. The engines also had an overboost feature for the turbo, which allowed an extra ten percent of boost to be added for up to ten seconds. Combined with larger injectors at 82mm, a fifty percent bigger intercooler, and a carbon fibre air intake (a first for Ford Australia) with better airflow, Ford Australia said the overboost would deliver 370kW and 650Nm of torque. Although the V8s sold well and were amongst the first in the world to feature what Ford called the VCT Modular design, they simply didn’t grab the attention as well as the six. Power outputs for the three valve V8s were reflected in the names, being Barra 220 (472Nm) and Barra 230 500Nm). The grandpa’s axe straight six’s heritage and strength have it in the part of automotive history marked “To Be Revered Because Of Its Legendary Status.” Long live the Barra.

History of the LS Engine

There’s a saying in the automotive world: “There’s no replacement for displacement.” Somehow, that tag became attached to an engine, in a vee shape and packing eight cylinders, made by Chevrolet in America. In the late nineties General Motors and Chevrolet debuted a new V8. Dubbed “LS” for “Luxury Sport” it’s this name and engine that have popularized the above saying. First seen in the 1997 C5 Corvette, the all “aluminum” block, called the LS1, was also known as the small block Gen111. It replaced the LT or “Luxury Touring” engine that had been a mainstay for some time. It was what’s called a clean sheet design; essentially a start from nothing design, the only common points the LS had with the LT was bore spacing and conrod bearings. Even in the LS range of engines themselves items such as the bore centre, at 4.40 inches, cross bolted six bolt main bearing caps, and a four bolt per cylinder head bolt pattern are common. Alloy blocks are used for performance oriented vehicles whilst blocks made of iron are used for SUVs and trucks. At 5.7 litres or 350 cubic inches in capacity, as the most common iteration is seen in, it produced 257 kilowatts or 345 horsepower. Maximum torque was 470Nm or 350 pound-feet, found at 4400rpm. It was bolted into a substantial range of cars such as the Corvette, Firebird, and of course in Holden and HSV cars like the Statesman and Senator Signature. LS6 is the name given to a higher output but same capacity engine largely found in the C5 Corvette Z06, with production starting in 2001. Peak grunt was bumped to 287 kilowatts and torque to 522Nm initially, with further development lifting both to 302kW and 540Nm. There were also smaller engines based on the same architecture. Engineered for use in passenger SUV and trucks, the LS1 4.8L and 5.3L blocks have a 3.78 inch diameter for the bore. In 2005 GM unveiled the GenIV or LS2 engine. There were bigger capacities, cylinder deactivation technology for improved fuel savings, and variable valve timing. Capacity went to 6.0L (5964 cc in real terms) or 364 cubic inches. Base engines made 300kW and 542 Nm. Holden and HSV saw this installed in cars such as the Monaro and Grange. L76 is the designation given to the LS2s fitted with Active Fuel Management or AFM. It was some time before Holden chose to use the feature; from 2009 it was installed however only in cars with an automatic called the 6L80. Power was rated as 260kW and maximum twist of 510 Nm came in at 4400rpm. Designed to assist in bettering fuel economy by shutting down firing in four cylinders, the engine gave rise to the L77. This designation defines the LS2 as being ethanol fuel compatible. Various engines with names such as LY5, LH6, and LMF were produced and seen in SUVs such as the Chevrolet Trailblazer and GMC Savana. LS7 was a rarely seen engine in Australia. It was intended to be produced for a specific HSV car here called the W427. Corsa Special Vehicles beat HSV to the punch here, with their engine producing 400kW and 600Nm. HSV’s version, first shown at the 2008 Melbourne International Motor Show, offered 375kW and 640Nm. A supercharged and slightly capacity increased engine, at 6.2L and called LSA, was released in 2009. This was first seen in the ballsy Cadillac CTS-V and Australia had it in the GTS, GTS-R, and Maloo R8 LSA, just to name a couple. 480kW was the peak power and an amazing 754Nm of torque. These came courtesy of a block with revised compression, cast pistons, and a “blower’ of 1.9L in capacity. With Holden ceasing local manufacturing in late 2017, the LS engines are now only to be found in cars already on Australian roads or in vehicles allowed to be imported from the US to Australia. For now….anyway. Stand by for Camaro. Keep in touch with Rare Spares and updates on our product range via our main website and for news and tips via the blog.

A Look into the Career of Allan Moffat

Although Australian motorsport has its fair share of locally grown heroes, there’s one that hails from Canada. He’s a name with a familiar voice to many thanks to his 1970s TV adverts for Ford and Victa but it’s his on track prowess that he’ll be remembered for. He is, of course, Allan Moffat. Born in the double tongue twisting city and state of Saskatoon, Saskatchewan, in November 1939, Moffat became an Australian citizen in 2004. He had been eligible since the early 1970s but said he’d never bothered to follow it up. It was in the mid 1950s that Moffat and his family arrived in Australia, after his father, who worked for tractor manufacturer Massey Ferguson, was transferred to Melbourne. Moffat commenced his racing career, which would span twenty five years, in 1964, co-piloting a Ford Lotus Cortina. The venue was Sandown Park and the race, the Sandown Six Hour International, was a precursor to the Sandown 500. What was called the Australian Touring Car Championship saw Moffat enter for the first time in 1965, again driving a Lotus fettled Cortina. Travelling to the USA and back kept the taciturn Canadian busy for the next three or four years before finally settling down full time in Australia. It was 1969, the year of the first manned lunar landing, that would cement Moffat into Australian motorsport history. An interview with the US based head of Ford motorsport at the time after a ballsy approach by Moffat had one of seven Trans Am Boss 302 Mustangs become his drive and enabled him to take a tilt at the ATCC crown. The “Moffstang” as it’s now popularly known, was soon to be decorated with his new, and first, major sponsor, Coca-Cola. It’s history now that the car, although a race winner, never did win the championship for him. Rule changes in the early 1970s saw the Mustang effectively retired from competition however Moffat had already established himself as a driver to beat in other Ford cars. 1969 was his first year in the Bathurst 500, driving a Falcon XW GTHO, and courtesy of a recalcitrant gearbox managed to miss the traffic jam that grew after the now famous Bill Brown rollover at Skyline. 1970 and 1971 were marquee years for Moffat, winning back to back at Bathurst, and also stamping his authority on the event by becoming the first driver to lead from the start and win. The car? The now fabled Ford Falcon XY GTHO Phase Three. Moffat, although known for driving and promoting “Blue Oval” products, also made his mark in other marques. The 1980 Le Mans had him in a Porsche 935. His co-driver was a soon to be famous Bobby Rahal. Moffat also drove a Porsche in the 1980 Australian Sports Car Championship. 1981 brought with it a change of direction for the bespectacled Moffat. Enter Mazda and its ground breaking Wankel rotary engine. Four consecutive top six finishes, a second and a third in 1983 and 1984, and wins in the Australian Endurance Championships, plus his fourth Australian Touring Car Championship win in 1983 have this car and its timeframe in history etched in Australian motorsport folklore. Of his friends and rivals, it was perhaps Peter Brock that would be rated the highest in Moffat’s opinion. The pair would race together on numerous occasions, including one memorable outing at the 1986 Spa 24 Hour event. As part of a two car team from HDT they won the Kings Cup, an award for a team that had the highest overall placings for at least 3 of their cars at the end of the race. After Holden cut ties with Brock in 1987, Moffat bought a car, a VL Commodore SS Group A that had been readied for an assault on the World Touring Car Championship to be held in Europe. The car placed seventh yet after a remarkable protest saw the top six cars, all factory backed BMWs, disqualified, Moffat and co-driver John Harvey were declared the winners. A return to the Blue Oval came in 1988, in the form of the Sierra RS500. Although a troubled car, Moffat did win in one in 1988’s Enzed 500 at Sandown. What was then called the “Toohey’s 1000” would be Moffat’s last at “The Mountain”. Driving with Gregg Hansford and along with Ruedi Eggenberger and Klaus Niedzwiedz, the car would retire with a blown head gasket and a cracked block with just 32 laps remaining. It was his friend and co-driver Brock that would present the still strongly Canadian accented Moffat his Australian citizenship papers in 2004. After his 1989 retirement from driving, Moffat would go on to continue his strong association with motorsport in areas such as team management and television commentary. And, like his now departed colleague, Moffat has long lines of fans awaiting his time and signature when he appears at events such as the Muscle Car Masters. And forty years after that famous 1-2 victory at Bathurst in the XC Falcon alongside Colin Bond, Sydney Motorsport Park immortalized him by naming the super-fast Turn 1, Moffat Corner.
