yea, it does take a while to spool, but as soon as it does, there is no stopping it lol..

 

5.3 heads, cam, headers procharger p1 stock pistons and rods.

7 years never had a problem.

Now lsxrt intake 8 psi 50 shot, a 2bar tune no dyno just looking for a 6.999 1/8 only 8 psi because blower is maxed out....

 

are you saying the P1sc is maxed at 8psi on your truck? we have made over 700rwhp with the p1.

 

whats up with the huge loss of power in the mid range, both hp and tq drop

 

I think so procharger say 62000 max impeller rpm speed. Internal gear 4:10:1
3:40 pulley shift at 6700 and stock crank pulley or is my math off....? I may just need to rebuild it...

The numbers I posted was on a different pulley just don't recall what it was.
