Has anyone used a 7pound pulley on there M1 procharger on a MPI MOTOR with sucess. If so what did you have to change.

no one here runs a procharger more than 5 psi??????

I am almost afraid after bajas comment. When I bought my boat it had a seven pound pulley on it , so the gauge sais. After the first season I changed alot of stuff. To much for my slow typing fingers. If you like pm me your phone number and I will call you and talk about it.
