[QUOTE="Colt .45, post: 11863555, member: 4126"] Right now I am running the 3.0 pulley on my 2.3 Whipple. I am running 93 octane and making 569hp/517torque SAE. My Autometer boost gauge reads 16psi. Will the 2.75 pulley be ok to run with 93 octane? Going by the boost chart the 2.75 is for 19lbs. Theoretically since the 3.0 I have now is for 17lbs and I am seeing 16, I should see about 18 with the 2.75. Is that about right? Also, my tuner said my fuel mods will support a smaller pulley than what I have now. Which are: Stock pumps BAP 60lb injectors What do you think my numbers would be with the 2.75? [/QUOTE]
