hourigan218 Posted November 8, 2015 Report Share Posted November 8, 2015 I know adding a 15% lower will help boost psi but I'll be adding cams and that will drop about 2-3lbs. I just had car retuned by lund and found out I was only at 15.6 psi so I'm looking to get an upper pulley that still has the s.s. logo on it and still keep the boost at about 17 psi.

william strauch Posted November 13, 2015 Report Share Posted November 13, 2015 With the hole shot pkg. On my SS it is 14.7 psi. From what I was told this is due to the cams and headers. The lower psi is to protect your bottom end, unless you beef it up. Mine is a 2014 @ 830.22 rwhp. Quote Link to comment Share on other sites More sharing options...

The only two Super Snake logo'ed pulley's that I have seen are the original 2.8 KB pulley and the larger diameter 3.6LC KB pulley that were/are part of the standard Super Snake build. I have not seen any smaller 2.8 or 3.6 pulley's that also include the unique Super Snake engraving. R Quote Link to comment Share on other sites More sharing options...
