Why is this not making more than 6psi
Why is this not making more than 6psi my p1sc running through a 4 inch intercooler is having a hard time getting to 6psi. I switched from a 3.4 pulley to a 3.2 it seems to get to my boost level faster but then seems to stop. I thought maybe belt slip so i put a 35.5 inch belt on and its very tight. I had a tough time getting that belt on. I'm wondering if maybe the bosch style bypass valve is blowing off all my pressure. When I let off the gas I can hear it but under boost my car is to loud and I have no idea if its blowing off. Anyone got any ideas why its not making bigger boost. I do live at a high altitude so I realize that will affect it a bit and pressure drop through the intercooler will. But I thought this pulley would make almost 10psi.
yeah its mostlikley the BOV , how to you have it hooked up???
Make sure you have it hooked up to your break booster vac source, if you have it hooked to the port on the back of your intake , there is a check valve that will restrect vac to the BOV and not close it all the way , this will bleed a lot of your boost off, and you wont get much boost . It happened to me, and i was only seeing like 3 psi with a 9 psi pully.
Also Procharger makes a break booster manifold T that goes in line of your break booster vacume line and this is a great source of vacume for your Boost gauge BOV etc,
call them and order one of these, the Corvetts kits come with them
hope this helps you
