Found my HP problem - ZR-1 Net Registry Forums

Thanks for the input guys. As we know not all dynos are equal or accurate for that mater. I suspect this one was not real accurate. In this case, same day same dyno, karterdon put down 358/349 on his 91'. He has similar mods but no headers and is using a full Corsa cat back. So this gives me a point of reference. I have headers and the modded Corsa, but only 10 more HP?

As for my mods, I do not have any head work other than port matching the IH's and the cams have not been timed. Based on several other cars I've seen numbers on, with the same mods, I should be in the 385 to 395HP area.

Paul can you give me the dimensions of that magnaflow resonator you have? Length, width, height and most importantly what is the center to center distance of the piping going in and out. Thanks
