It’s not often that you get the chance to rebuild an engine from the ground up, and even less often that you get to rebuild something like a C7 Z06. But when you’re Vengeance Racing, it’s almost common place at this point.
This build, a ProCharger conversion, started with a pair of ported LT4 cylinder heads and a Stage III camshaft kit, an American Racing header system — long tubes, of course — a triple disc clutch kit, and an F—1X supercharger. This Z06 engine is the stuff of legends. It’s also equipped with a VR oil catch cap, a Vengance Racing auxiliary fuel system, a methanol injection system, and some of the sexiest body panels that you’ve ever seen.
Putting this beautiful engine on a dyno almost seems like a waste of its potential, but the results of the dyno testing are enough to blow your mind. The RWHP depends on the type of fuel in the engine. Starting off with premium 93 octane fuel, this Z06 engine managed 829 RWHP.
With E85 Ethanol, the RWHP climbed up to a mind boggling 947 RWHP, but they didn’t stop there.
With C16 Racing Fuel, this custom Z06 climbed to an astonishing 1064 RWHP. Yes, you read that right — after the rebuild, this engine manages more than 1000 RWHP when filled with racing fuel.
For comparison, a stock Z06 puts out about 448 RWHP when tested on a similar dyno. The rebuild more than doubled the RWHP output of this stock engine.
This might not be the kind of engine that you want in your daily driver, but it is still a great representation of the hidden potential in those engines. A stock Corvette Z06 is a fantastic daily driver, but if you need some extra power, a build like the one we listed above can easily take your little Corvette to new heights.
