Default Procharger pulley PSI
To my knowledge the P1 makes around 6psi on a 4.25 pulley, how much boost do the other available pulleys make?

Also, how far can you go without belt slip being a concern?

I don't think you will face a belt slip with a 8 rib on a p1,

On a 8 rib set up & with now using the new set up from A/A you will not have any problems at all.

Mine is at the dyno today with a 3.85 pulley (from a 4.25). I'm expecting 9 PSI.


I can update later in the day.
