hey guys, i am new to the whole sc scene. i just recently bought a near complete used comptech kit. it is missing the crank pulley, but i was figuring on running a higher boost than stock anyhow.

do you guys suggest 9lbs or 7 lbs?

also, i keep hearing people talking about asp pulleys, but for some reason no matter what i google, i cannot find a site to purchase an asp pulley. also, will a normal belt from autozone work for this application, if so, do these belt numbers and pulley sizes for the boost seem accurate?

Stock pulley size: 4.30" (5.5psi) Belt: 4060400
4.25" (6psi) Belt: 4060395
4.00" (7psi) Belt: 4060390
3.75" (8psi) Belt: 4060390
3.50" (9psi) Belt: 4060385

thanks everyone, dustin.

 

PM kane.s2k,he can make you a custom pulley and get you a belt for it.




peace

Crank pulley is different than boost pulley.

There's only one size on the crank pulley and you'll likely have to order a replacement from Comptech. The boost pulley will be directly attached to the snail.

 

kane doesn't do custom pulleys himself. He sells the ASP Pulley.


PM him either ways though. HE can get you the right size pulley.

PS: def. 9lbs since it is going to cost the same. Why lower power

 

^well it depends if he wants to buy an engine management system for the higher than 7lbs of boost.

 

i plan on purchasing a vafc 2. if i choose to go to 9 lbs of boost on the ctsc, using a walbro 255lph and aem hi press fuel regulator, will the stock injectors suffice?

 

I got my 3.5 asp pulley from a member on here, pushing a little more than 9.

 

My experience was the stock injectors should be replaced above 300 rwhp.
