Harrop Teams With Forgeline to Win 3 Time Attack Divisions

Not one. Not two. But three divisions of the recent 2012 World Time Attack Challenge were claimed by our buddies at Harrop Engineering. Even though they finished 4th overall, Harrop took the win for Rear Wheel Drive, Naturally Aspirated, and V8 classes in their “imported” American Corvette Z06.  

In the video above Steve Moore, general manager of Harrop Engineering gives us the rundown on the team’s 2009 Z06 that they had converted to right-hand-drive specifically for this event. The car still has a full interior, and Harrop kept the formula fairly simple by using mostly bolt-on parts to upgrade the Z06’s suspension. For the engine, Harrop threw on their new prototype Hurricane intake manifold and air box and stabbed in a new camshaft. They even left the stock exhaust manifolds in place, and added a gorgeous titanium Evolution cat-back exhaust from Akrapovic. When all is said and done, the LS7 now makes somewhere around 670 horsepower.

The classes Harrop competed in required the use of a “street tire” with a tread wear rating of over 140. So they went with tried and true Michelin PS-2 tires 315/30/18 and even bigger 345’s in the rear. For wheels, only the best would do – so Harrop put the PS-2s on a set of Forgeline’s GA1R Wheels. With its I-beam spokes, forged 6061-T6 aluminum construction, and open lug design – the GA1Rs are a serious set of race rollers. “Forgeline wheels has come up with a fantastic fitment [for this car] of their lightest and stiffest wheel.” Says Moore.  Check ‘em out here.
