Procharger 3.35 pulley / how much boost ?

A guy just brought a car to me to work on , and I am wondering what kind of boost the car should be seeing with a P1SC and a 3.35 pulley on it , its got the 3 core intercooler and trickflow top end kit on a 331 stroker ? The guy said he was told the car should make 15 or so lbs of boost , but I find that hard to believe , he said he has saw 11lbs of boost is the max he has seen and I think that 11lbs is about right , but he thinks the bypass valve might not be holding ....does anybody have any experience with prochargers on a sn95 that can enlighten me on the boost that this car should be putting out ????


Thanks
Willie

I have a D1SC with a 3.35 pulley and mine made 11.7 psi on the dyno at 5,600 rpms with the mods in my sig.

well this is a P1SC and he said he saw 11 on the boost gauge , car he told me today actually has a Z303 cam so hes probably losing some boost with that cam since I believe it was designed for NA use ......so 11 lbs is probably about right ....
