Heres my ONLY existing dyno sheet. I can not prove mt 270hp because I dont have the sheet. Another trip to the dyno is soon comming.
gt-40 heads, cobra cam, cobra intake.
BBK equal shorties, BBK o/r X and MAC pro dumps
UDP's, 70mm tb, CAI, 15° timing, and a 15.5:1 air fuel ratio.
253.5 rwhp and 294.7tq

i told him 240 so i wasn't that far off. well it also has lt with a prochamber and flows but that shouldn't make that much of a difference

i think i could have seen at least 350rwhp with the afrs that i was saving for with boost friendly cr.
i can't wait to throw it in his face.
he wants to race me in the notch once i can get a motor together

I'm not going to take the time to scan the sheet, but in January my car made 257 rwhp through the AOD with my mods below. That figures out to 290ish through a manual. Bear in mind that mine are aluminum GT40X heads and probably make significantly more hp than regular GT40's.

RE: GT40 Heads and DYNO SHEETS
Adder, are you always such a dick?
The accepted ratios for powertrain loss that I have always heard of and used are 25% for an automatic and 15% for a manual. Using those numbers, my 257 translates to 342 crank horsepower. Coincidentally, that's within two horsepower of the FRPP crate motor that uses the parts I have on mine, so I'm pretty confident that my hp number is good. Now, if you remember your4th grade arithmetic, take 15% off of 342 and what do you get? 291.266666666.
Any questions?
