Hi I will install a comptech sc on my s2k and I want to get a higher compression pulley. I want to know If I go to 7 or 9 psi if I leave everything else stock it would cause a problem? I think the stock comptech pullley pulls 5 psi? I also want to know the cost of a pulley and where to buy it.

Thank you

 

7 psi u dont have to do much except get it tuned. 9 psi u are gonna need to get engine management, bigger injectors. get the pulley at automotivespeed.com

so with the 9lb, if i have the 750cc injectors and aem ems a little tuning I should be good with the stock block?

 

10psi pulley at Science of speed.com

12 and 14psi pulley need to all ASP Racing

 

I have a 7 lb pulley, took it off to do my upgrade.

 

That was going to be my suggestion as well.

 

So can you run a 7 psi pulley with stock injectors and a stock ECU comfortably?

Also, one more question, the Comptech S/C comes with a 6 psi pulley correct?
