Super Charger Pulley

How do you determine how much boost a pulley produces? I am looking for a pulley for an Eaton M112 that produces 11-14 PSI and I have n clue where to get one.

11-14 is kind of a broad range. Be more specific...

It all depends on your combo. When my car had the stock motor with just longtubes and o/r x pipe it made 10 lbs of boost with a 3.5 pulley. Your supposed to pick up a lb for every .1 you drop in pulley size. When I built my motor I put stage 2 heads and blower cams in. I put a 3.2 pulley on and only got 11 lbs at 6500 rpms.

the amount of air flowing in and out of the engine can have an effect on boost as well...keep that in mind..

So can the weather outside...

+1 So can altitude. I have a friend here in CO (5000 ft), and he has an 06 GT with a Whipple SC. He wanted to run 10 psi (max recommended by Whipple on stock bottom end), but with a 10 psi pulley he only had 8.5 psi because the pulley was meant to run 10 psi at sea level. So he swapped it out for a 12 psi pulley and now he's at a dead even 10 psi.
