I have a V-2 S-trim supercharger with stock pullies. I'm only seeing 5 psi of boost. Does it sound ok given the parts I have? Look at signature for combo...

1995 Mustang GT Rio Red with red and black leather interior (1 of 20 made by Ford), Vortech Supercharger, UPR powerpipe, Edelbrock 6037 heads, C6 transmission, 3000 RPM 9" torque converter, Bassani Offroad complete exhaust system, 1.7 roller rockers, 3.73 gears, Holley Systemax I lower intake, Cartech Box Upper intake, 65mm TB, Pro-M 80mm MAF, 42lbs injectors, UPR Power Pipe, Tweecer, and some other stuff...
I only saw 5-6psi of boost with my combo and stock pullies at 5500-6000rpm
No data yet with the smaller pullies, waiting for the snow to melt.

How much I could see with a 2.95 pulley and the stock 6.87 crank pulley? How much for a 7" crank and the 2.95 pulley?

what was your engine RPM at your highest point of boost. 5psi. sounds really low, i have a V1-S with a stock pulley and i am seeing a max of 9psi.
Just remember that boost is going to vary depending on engine combination as it is a measure of back pressure. The better an engine flows the less manifold boost it will see for a given pulley setup/blower ouput(CFM).
That said, I think 6-8psi is reasonable with the stock pullies and 8-12psi with a 2.95" pulley. The 7/2.95" combo might be 15psi but I am only guessing. Not sure if this combo will overspeed the blower at 6000+RPM?
