Re: How much HP from an 02-04 Z06 with Bolt-on Mods
My car had 358 with stock tune, and according to my tuner, who owns a corvette, the loss is about 65. That works out to 423 hp at the crank. I have seen half a dozen write ups about the c5z, and they all say the engine is underrated, and makes more like 425. That's about 16 percent. It probably isn't the same at all throttle levels, and probably increases with hp. Mine is at 407 rwhp, and I'm at 90 percent injector load at wot, with 28lbs injectors. Can this info be used to extrapolate the true hp? And the corresponding parasitic loss?
