[schoffs4]

Got finished building 4.6 stroker to 5.0 got the car broke [bent rods because meth relay stuck on ] with vortech snow meth injection. it has under drive pulley on it with 3.12 pulley on SC he said he had 12 psi boost, cant be think he's bs me had to send sc to vortech for some bearing noise i didnt like. Thinking of removing underdrive. Have full forged low end what boost should i have with 3.12 pulley with stock pulleys. I cant believe he was underdriving the SC correct me if im wrong please

I have a 4.6 stroked to 302 with stock bottom pulley and a 3.12 on a V2SQ and I had over 13 lbs...

I also have a front mount intercooler and port/polished heads...

you need to take the underdrive pulley off..

take the UD pulley off.
i'm actually running a 10% OD crank pulley

You must have stock pulleys with a supercharger.

yes...12 lbs sounds right with a 3.12 pulley...no problems there...
