realistically, if my last dyno was 300rwhp,(which is a little suspect, due to the drop in HP from normally 320rwhp) what would you project that the gains would be? 10hp , 20hp?
as far as this "suspect" dyno run,, i think that the car was strapped down unusually tight, compared to the other 12 runs ive done at this dyno. I think a good test for everyone, that i havent done in a long while is the coast down test. at least then, you can factor out rolling frictional forces.

I can't project any expected gains..... all I can say is that a SharkTune will enable you to set mixture and igntion for the optimum result. According to your own cook book recipe....

Yes, all we know is the cams are US 85s, and compression is 190psi per hole, and it is marked M28-41 00007 However, i dont think we are going to find any thing special about it, especially since it turned almost the exact same hp as a GT with the same mods, as well as the same shaped HP curve. But, we wont know until i get it apart.
