First, I would like to say whats up to everybody on this site, you guys know your stuff. Anyways, I just got my truck supercharged at Magnuson. Its an 01 ECSB silv with a 5.3 with a shift kit and 3.73 gears with a factory locker. The dyno showed 370 rwhp and 391 rwtq. Is that above, below, or just averagepower over stock of 250rwhp and 275rwtq. What do you think I should expect for 1/4 mile numbers? I'm going to eventually upgrade to a smaller pulley along with a more aggresive tune, Nelson tune probably? You guys seem to say good things about him. Is the 3.60 pulley the one that the radix comes with? Need to go smaller! More boost! Thanks guys.

 

damn, you got 250rwhp stock?

I'm lucky if I'm getting two and a quarter!

 

It's probably a 3.4",the size is on the pulley.A couple of site sponsors offer smaller pulleys.

 

go get a 2.9 or 3.1 pulley, that shold bring it up around 10 psi.

 

that power sounds right
