Does anyone know where i can find out what size pulleys put out how many psi? This is for a vortech V2

Thanks

It all depends on the rest of your setup, but the stock 3.47" (I think) pulley makes about 8 psi, and you go up 1-2 psi for every size smaller. But lots of stuff can play into that, like whether you have long tube headers, the size of your crank pulley, etc.

+1 Generally, one size drop will be 1-2 psi difference at the blower. But the net effect will vary depending on the rest of your system.
I have a 3.12 6-rib vortech pulley I'm getting ready to sell.

pulley size doesnt always = set PSI, too many variables to be accounted for

stkjock what all do you have done to your car? I have an aunt in east hampton if i cant find a place close to home to get a tune, when I come visit her I may have to hit you up for some advice on a good place to go down that way.

Jeff - sure can... let me know ...... where r u?

IMHO - best shop on LI for a 3V tune is Realspeed in Bohemia. They have done all my work

i am located about 5hrs away. But the closest shop that does good work is about 3.5-4hrs from here. I have not found anyone that knows of a shop closer. I am located in the corning elmira area.
