The name Pro Speed Racing has long been associated with Subaru performance. They are the importer and reseller of many leading USA brands like Invidia exhausts, Mishimoto Radiators and APR Aero. For 2016 the Pro Speed guys have entered their Project WRX into WTAC to showcase what they can offer to their clients.
“We had planned on entering in Open Class,” said Pro Speed boss Troy Patterson “but with the aero kit already outside the rules we had to move up to Pro Am.”
“Being in Pro Am will allow us some more freedoms in the future but the bottom line is this is not a bespoke racing car, it is a car that anyone could build using parts all available from our online store. It is a rolling showcase of the products we sell and also an extremely good R&D vehicle to test and prove new techniques and products in a real world environment.”
“It all started life many years ago as street MY02 WRX STi but is a long way from that now!”
The engine is a 2.5 Litre closed deck with all forged internals. Everything is top shelf, Nitto Rods, CP Pistons. Being the Blouch dealer for Australia Pro Speed didn’t need to look for for a turbo and opted for the brand new Blouch Dominator, twin bearing 2.5 XTR. The whole deal has been screwed together by Michael South of MSR Engineering on the Central Coast.
“We constantly developing new techniques like gas rings for example. It is a continual work in progress and you never stop learning.”
The cooling is all Process West and the exhaust is Invidia 80mm G5 Titan. The fuel system runs three fuel pumps in a Radium Engineering surge tank feeding E85 to the Deatchworks injectors.
“Currently the car is only making 337kW at the wheels,” said Troy, “But the big deal here is the torque which is what we have designed the package around. It is now making an incredible 1190Nm of torque and is on full boost by 3500rpm!”
“We still have a lot to do before WTAC. We want to take full advantage of Pro Am rules and the aero is one area we are really focused on.”
“We have an ABW designed APR performance wing and an APR composite front splitter but we still need to fabricate skirts and a big rear diffuser and of course some canards. If time permits we would also love to put some bigger tyres under those guards.”.
Josh Coote from MCA Suspension has been instrumental in helping with custom valving and setup of the MCA Red coilovers. The fact that a majority of the fast cars at WTAC all run MCA suspension is testament to another quality Australian product making a noise on the world stage.
“We might not be a threat to the guys at the front of the pack but we plan on putting on a damn good show and show what can be done on a modest budget and using mostly off the shelf parts” said Troy “We will probably let Michael South have a pedal as well after all the hard work he has put in, plus he will be a fair bit faster than me I suspect!”
“Pro Am is certainly the class to watch this year” said Superlap CEO, Ian Baker, “with some very innovative builds, the class is bristling with new technology and interesting concepts. Bring on October!”
