JRSC pulley and belt

[FLounder]

im confused about what pulleys make what psi. i have 4.0 and 4.2

ive heard of people using a b20 pulley to raise the boost on jrsc...

i have a b20 and want to get 10psi out of the blower... anyone know about this stuff?

Right now I'm at 10psi using the Jackson Racing crank pulley and the 3.8(I believe) pulley. Another way you can get there is by using a CRV crank pulley. Finally, there's a company that makes a different stepper pulley (one on the alt.) that does the same.

The smaller the blower pulley is, the more boost it will make.

The bigger the crank pulley is, the more boost it will make.


You need to see what boost you are running right now with what pulleys and adjust from there.

i can see that this is going to be a pita to figure out what belts i need

i have several other pulleys besides the two that i mentioned before for the supercharger itself. im just not 100% sure where they go. the guy i got the kit from said it had everything there to make it any amount between 6 and 11 psi. ill take some pics and see if i can figure out whats what....
