| There's an engine bay you'd call MAYHEM! In a car yard I used to work for, they had an HSV GTO coupe (VX spec) with this crazy twin turbo plumbing, all of which was hidden below the bonnet. It had a smooth cam, yet this thing was putting out about 600 horsepower. Didn't get to see it too closely, but two huge intakes dominated each side of the engine bay. If this one had a lumpy cam, and went for either one huge turbo or two smaller ones, 600 horsepower may be a conservative estimate. Never underestimate the potential of a Holden V8 fiddled with! |

Without even pushing it hard, it sounds like something that would bite very hard, if given the opportunity. Some engines have heart from day one, if you mess with them as well, they turn into feral animals.
Knew a bloke whom had what started as a stock VH with a 308 and an M21. It would start smoking in 1st, through to 2nd, and 3rd, before getting traction in 4th. He wasn't holding his foot on the brake, this was wheelspin from a hard takeoff. He finally decides that he wants more power; balanced, blueprinted, oversize valves, 650 double pumper, headers, and a 3/4 cam. It now won't idle below 1000, and is sporting a new paint job. Imagine Peter Brock's Bathurst VH, paint it dark green and add tinted headlight covers. We're not entirely sure what it could do down the 1/4 mile, other than *****in' FAST! |
