hey verybody just curious on how much boost your seeing with your p1sc on your LT1 what size pully and what not...thanks

 

still wondering

 

with a 4.25 blower and 7.65 crank pulley on the stock motor i saw about 8psi. then with 3.55 blower and same crank pulley it made about 11psi. and with lower compression 383 and same blower setup plus sd-concepts bracket and 8-rib it made 14psi. guess the belt was slipping quite a bit with the original bracket.

 

the better the heads flow the lower the boost will go

 

true, the stroker has combo motorsports stage 2 blower specific heads. they flow pretty well. but they are stock casting so limited to lowereing compression with them a lot. thats up to the pistons.

 

with a 4.25 blower and 7.65 crank pulley on the stock motor & ported LT1 heads & a twin intercooler setup, I was seeing 7 psi.
