I need to get a 10psi pulley for an ap1, but don't know the size to get. Can someone refer me to a chart or let me know what size to get?

Thank!

 

10 lbs at what redline?

You probably need something around 4.3 or 4.4 inches.

May I suggest you just get a 4 inch pulley and try not to smile too much.

Here are some links to the stickies at the top of the Forced Induction Forum.

 

Man, I just installed a 3.6" pulley (Comptech) car and I am so anxious to start tuning this weekend! I can't wait what it feels like to have a bit better lower end grunt (not to mention the top end pull). I'm gonna drop the hammer on some Evo's over at Miller next spring.

Keep the rubber side down...

4" put you at about 12 psi @ 9000 right?

Been debating going 12psi. How's the reliability Sideways?

 

sweet thanks

 

I think you will be fine since you have the AEM EMS.

I broke a ring land at 16 psi after 7 years of abuse including 3 boosted. The F20C piston has been designed for NA and not boost.

 

anyone recommend a place to get the SC pulleys from???

 

Vortech sells the direct. ASP also makes custom pullies.

 

vortech sells how big?
