[NO SLO PK]

My vote is Procharger! I had a friend that ran 17psi on the intake/21 at the discharge on super unleaded and 10 degrees initial timing. The 3 row intercooler helps...cools to about 25 degrees above ambient. He was using a D-1. His trap speed was claimed to be 123 mph with a STOCK long block and shorty headers.

Because of my friend's Procharged 5.0, I sold my KB blower and made the change.
