Building a competitive Time attack car takes time, money and a bucket load of dedication, sleep less nights and tight deadlines are just part of the deal. Mike Mahoney owner Wallace Performance definitely has the dedication needed and along with his team have produced a car that is truly outstanding in terms of looks and power.
It all started at the end of the 2011 TA season, the car was already at a decent spec and it was also quite competitive but Mike knew to run with the big boys in TA he would have to go all out on his Evo 8 and push it to the next level.
A plan was hatched and the car was stuck on the ramp at WP HQ and ripped apart, everything would have to be stripped so the car could receive a full ground up rebuild. I’m not gonna go into the full build here but the full run down can be found here.
While the car was out of action the engine was sent away for a full rebuild. Mike chose Norris designs to do the engine work as he knew Simon could build a high spec and highly reliable heart for this soon to be beast.
The engine block is based on a 4G64 block and bored to 2.37 ltrs, oil delivery to the block is taken care of by a ND dry sump system. ND special cams and solid lifters join HKS pulleys and a ND stage 3 cylinder head. A Magnus manifold feeds the intake side of the engine while a Shearer manifold handles the exhaust gases escaping the block which push the mammoth Garret GT42R turbo. The gases finally escape down 5″ diameter pipework through the custom WP side exit exhaust. A custom WP twin entry fuel rail feeds the 2000cc injectors which is all controlled by a Motec ECU with custom map work by WP’s own Matty Lawson. The result?? 1060 BHP @ 3bar of boost!
The radiator and fans are now located to the rear of the car to help the all important weight distribution and also keep the water even cooler in the back of the car.
They are fed via NACA ducts down through 5″ air tube into the boot
Cut outs in the carbon boot lid let the air escape into the atmosphere. Mike also kept the PAS which now resides in the boot aswell along with a ATL fuel cell and twin pimps.
To cope with the power increase Mike needed a new drivetrain, a Samsonas dog box mated to a drenth sequential shifter does all the hard work through a Shep trans transfer box. The CTG carbon prop shaft delivers the power out to the rear wheels via an RS spec rear diff.
With the engine and drive train taken car of Mike knew the exterior would have to match the power. Taking inspiration from Japan Mike settled on the Voltex Cyber Version bodykit. Flashy exterior paint wasn’t gonna cut it so he went with plain white paintwork as he knew that WP decals and the as the compulsory TA stickers would be attached to the car. A super huge TA spec rear wing was added to the rear along with some WP wire braces to make sure it doesn’t excessively flex when driven hard.
For the 2012 TA season the organiser’s finally fell to peer pressure and changed the rules which allowed the competitors to run full slicks! The car wears Rota Torque wheels with ex GT3 cup race car Michelin slicks
Suspension duties are taken care of by EXTEC, their suspension was on the car for the 2011 season and Mike really liked it. Custom Momentum Motorsport subframes support the rear diff and engine with help from Torque Solution’s mounts.
Brakes come courtesy of AP racing they are more than enough to haul the lightened shell to a stop. Mike also installed a full air jack system to save the guys having to carry jacks to and from the circuit.
Interior wise only truly gutted insides would do, Corbeau seats and TRS harnesses keep Mike pinned in the car when in full attack mode. A Tilton pedal box is mounted on the floor and slightly further back then standard along with the seat and steering wheel to help out with the car’s weight distribution.
The dashboard was cut down and flocked, only essential buttons were added back into the place of the OEM radio.
A racelogic box joins the Motec digital dash, this lets Mike see exactly what is going on with the car in real-time whilst on track.
With the car complete it was time for Mike to get the car out for some major shake down test’s at Knockhill and Crail but the cars first true test was at the 30-130 day held at RAF Marham, best time of the day was 8.14 secs to 130MPH and good for a 3rd place finish, pretty good im sure you will agree!
And so onto this weekend and Time Attack, it will be the cars first outing this year due to conflicts with dates for Mike and its his “home” circuit Knockhill, im sure the car will perform amazingly .
I wish the guys the best of luck and hopefully Mike can get the car on the top spot where it belongs!
