Dyno Video 1991 l98 c4 corvette cc502 cam HSR intake

Your numbers are not that good really. My 91 L98 with 147k miles put down 213hp 309tq with only flowmaster mufflers and a k&n air filter.

@jlah69 I Know they did it wrong and the tune was a little off . It should have made at least 20 more HP but the guy running the dyno let it downshift then he gave up on it. It was a club dyno day and he had alot more to do so i never got another chance.

That really doen't matter anymore.. Im bolting down some Fast Burn heads as we speak.

u should upload a video of acceleration with the hsr so can get an idea, that sounds awesome

268 horse power at the wheels is pretty much around 320 bhp, so that pretty good with stock heads, about what i am looking to get at when i do the hsr swap also. I only got zz4 cam though, so probably be slightly less.

@mavidatt I wish I could post the graph because he wasn't in it all the way when those #s were recorded. It has more left in it. Right after it made those #s he hammered it and it downshifted then he aborted the run. I Have to have it done gain it was a club dyno day and they were in a hurry no time to do it again.
