[QUOTE="me32, post: 16658123, member: 34543"] Honestly 20psi is much better aslong as you can run it on pump gas 91/93. Keeps the tq band better. What size pulley are running on your setup? 2.9 on the 4.6 takes more to turn it. Personally i think anything less than 18psi on it becomes a waste. The 2.3 whipple at 15-17psi on a 4.6 is much more efficient than a whipple 2.9 at 13-17psi on a 4.6. Being all things equal. [/QUOTE]
