what pullies for 6-8 psi

[crazygn]

i have a 8" crank and 3" blower pullie now and iam looking to go with about 6-9 psi if thats safe for a stock motor, what size crank and blower pullies will i need to run that boost level.


what should be ran on a stock motor, is 8-9 psi to much.

You will need the stock 6.87 crank pulley and the 3.33 blower pulley.

8-9 psi is ok on a stock motor if the tune is correct.

so i guess i'll get them pullies and hook the kit up, send it to the dyno to get tuned.
