This is why I wont buy Powerdyne again... it was all cool and all untill I
maxed out the boost at 8PSI (w/ 14PSI pulley, no belt slip) once I had
heads/cam on the 318... hell, I doubt it'd push 4PSI max on the setup I
have now... the same setup w/ a Vortech T-Trim on the 318 that made 14PSI
makes ~8-9 now on my 360... (mucho better air flow)
I always say if you are thinking about powerdyne, make sure you're not
plannin on running high boost, or looking to make your truck into a
drag-truck.... too small IMHO...
