[QUOTE="SnakeBoostE85, post: 14442711, member: 160175"] I'm at pretty high altitude in Colorado… live at 7000, drive between 5000-8000 feet. DA's in the summer reach 9000 sometimes. So I run a 2.75 pulley on my whipple 2.9 and its pegging my overlay boost gauge around 20-21 psi max. Its E85, return fuel system, AFCO heat exchanger, cooling mod for the heads. I have it currently running between 11.7-11.9 AFR (gas equivalent). I test my fuel a lot because is can be inconsistent in Colorado. I've seen a few stations pumping out 72%. But I always try to run 85 or better. I haven't dyno'ed it up here, but in Florida it had a 3.5 pulley at 19-20 psi and it made around 680-700 to the wheel. Pretty conservative. [/QUOTE]
