where can i get a 10 psi pulley for my JRSC GSR besides the crv crank pulley?

Endyn stepper pulleys from Payn Tech:

i thought the endyn stepper pulleys were only 9lbs...

I know that that is true for the H22 JRSC pulleys, have no idea about their pulleys for other setups.

Use an Endyn stepper pulley and a LS crank pulley , You should be right at 10-11psi.

I think a 3.8" blower pulley would do the trick. I wouldn't stick that in concrete though.

i was trying to find a pulley that was made for 10lbs. i know that the crv and ls crank ones will work but i have heard that they are not made to spin that fast and cause other things to wear prematurely.

A lot of guys use the crv pulley. I've never heard of that problem, but I can't say for sure. I used a MVM stepper pulley, but it only gets me to 8 psi on my ITR. I think it is a little higher on the gsr. Stay away from smaller blower pullies. Since they have less surface area the belt is more likely to slip.

I have run CRV and LS pulley on so many cars I can't keep track of. If you run at 8000rpms all the time with the A/C on you may have compressor problems, Other than that you will be fine. As for the small blower pulleys, you will have belt slippage problems.
LS crank, Endyn stepper pulley and a 4.2" = 10 psi on a GSR,
LS crank, endyn steper pulley and 4.0" = 11-11.5 psi on GSR.

what pulley would i use to run 8-10 psi on my 98 ls motor with the jrsc?

A CRV craank pulley would get you right 10 on an LS.
