i just installed a 2lb lower (8'') pulley on my 01 L and I make just a needle shy of 14lbs of boost! This is on a Autometer Phantom and the temp was 62* F. It was on a 2 AM highway run and was 0-135 mph. 10.5 psi in first 13 psi in second and almost 14 psi in third? Is this pretty odd for just a 2lber. By the way my mods are CAI, Predator Pulley Tune, Accufab, 2lber, Port matched plenum, Bassanni, and Efans. Thanks for any replies!

 

you sure a 2lb is 8 inches?

 

No way. Mine weighs about two pounds (flaccid), but is way more than 8 inches.

 

On the internet, everybody has a huge *****

 

measure your upper pulley. i would think 12 wouldn't be impossible, but 14, something ain't reading right. measure your upper pulley... OR, maybe that supercharger is ported (which might net you 13 with a 2lber)? are you the only person who has ever owned that truck?
