How much boost Prochager HO kit 3.70 Pulley

[Dimitris550]

Does anybody know what the standard boost psi is for the procharger ho kit, for s550 5.0? It has the 3.70 pulley indicator stamped on the pulley. Websites who sell the kit advertise 8 psi, others around the web say from 7-10. Getting mail order tune dialed in. No larger intake piping or larger air filter on car, standard procharger piping and filter.

7-10... depends on way to many variables to give an exact number. weather conditions, tune, exhaust, max rpm, etc.

I have no clue what my HO kit with a 3.70 kit made for boost , I just know it runs 9.90s with a 3.50 pulley ..Changing to a 3.40 pulley this weekend ...I had to order a 106 & 3/8s inch belt .. the 107 & 1/8 inch belt that came with my 3.70 pulley is a bit to long for the 3.40 pulley ..
