I only got the brand new kit installed last week. It should has the latest pulley setup. What pulley size I need to get 9 to 12 PSI and do I need a new belt and a retune

Yes, that is the latest bracket. (Has been for about 7 years) Just was curious, because there are still some old kits running around from 10 years ago, though thats pretty rare.

You would need to go down about 2 pulley sizes from where you are at right now, to get 8-9psi. That is the most we would recommend on pump gas and a custom tune.

Contact 913-338-2886 or ts@procharger.com (have your serial number from your blower ready) and they will get you taken care of!

Thanks

That depends on three important factors

1) What it currently makes now
2) The fuel quality in your area
3) The tuner

The tuner would be best to answer that question.



Depends on what style bracket, what blower, what pulley, and what its making now. So best to call the tech line, with that one.

I just ordered the 4.10 pulley. I am hoping to go up to 9 PSI and do a retune.
