What size procharger pulley do I need for more boost??

[ravenr_1]

Hey guys,
Looking to up the boost on my 01 mustang right now I have the 12# pulley not sure on the size(came on it from ATI) I want to be in the 15-18# range but probably 18 bc I heard you lose 2-3 psi with the 3 core intercooler. Let me know what size I need and what you guys recomend. Reichard Racing is the company I was looking to purchase one from.

To make that kind of boost you need to upgrade to a D-1 or F-1 head unit. You might be able to hit 16 pounds with a 3.00 pulley on the P-1SC or smaller but would have to upgrade to an 8 rib pulley set up to stop belt slippage.

Keep in mind, it may also not be as easy as a pulley swap. I wouldn't be playing around too much with it until you get it back to the dyno and check out that A/F ratio.

its going back on the dyno asap. I ordered a MAFia and a boost a pump and its all getting installed and tuned once i get my pulley.
