I Have a blue SC pully on my car and idk what type it is or if it stock and just painted. I called NST they said all there stuff has there name on it but they did used to make a blue pulley. I know that ZPI made a pulley as well but has since go under. Just wanted to know what Pulleys on the car thatnks guys

 

do you have a boost gauge in your car if so how many psi you making?

 

i had the same thing bought it off e bay. thinks its zpi.

 

So that would mean it's a 9 psi pulley???

 

i think so

 

Looks like this to me...

 

Yes its the same color dose that one say NST on it any were?

 

Also my car has a Goodyear Gatorback belt if that helps any???

 

Just measure the diameter of the pulley and compare it to what NST sells.

 

If it is ZPI, note that they made a 9PSI pulley and NST makes the 9.5 PSI pulley so there might be some size difference there.
