i would use the kenne and bell it looks like they have their stuff together, or get a whipple intercooled and junk the electronics and put bigger injectors and send your pcm off to westers for a new tune

Stop yelling

Kenne Bell and Whipple are not centrifugal superchargers.

What size engine do you have? (I am assuming from your name, that you have an 04 2500 series.

Vortec makes some kits for 04 5.3 and 04 6.0 (LQ9) You might want to call them and see if they have your particular mutation.

Don't forget to shop for a higher stall torque converter. It is an essential part of using a centrifugal on a heavy truck.

I have the LQ4 6.0l and all i have found are for the LQ9 and 5.3 and 8.1. Any help would be appreciated

And whats the reason for using a stall converter when you supercharged these trucks?

dcairns · August 17, 2004

The general wisdom, when using a centrifugal supercharger, is to use a higher stall converter, that way you get into boost RPMs sooner. Centrifugals do not produce much boost at lower RPMs. They also increase boost exponentially as RPMs increase. So when you set you max boost and RPM, you wind up with a bit of a hole on the bottom end of the RPM scale.

I have a Magnacharger Radix, and it produces full boost right away, so it takes off from a stop pretty quick. The downside is that is it a bit hard on the drive train.

This is from Whipple's web site and exaggerates things (in their favor, of course), but gives you an idea what I mean.

Speaking of superchargers and 6.0s, I've purchased a Powerdyne unit for my 2004 SS Silverado. I've run into a slight problem, however, in that I cannot locate any 38-42lb. injectors because the motor is a marine-style engine (6.0 U). I've called around everywhere in search of some but it seems nobody makes them. Are they available anywhere? Has anyone here supercharged an SS Silverado?

You can try some 30# 8.1 or 42# 8.1 Marine injectors. The marine injectors come with the Radix kits I believe. You will need some tuning to get those running right. They arent too terribly cheap though. I think Arizona Speed & Marine sells the marine injectors for like $52 bucks a piece.
