Hi Folks. Hope You Do Not Mind...

Thank You,
I'll follow up on that. If there is anyone else please bring it on.
I am not up to a debate on the warranty issue right now but have you heard of the magnuson act? It is the law that stops automakers from voiding your warranty for accessories. Magnuson is Magnacharger. They will try, and try hard but you can beat it.
Bill Heard Kennesaw has two 05 Joe Gibbs Racing edition trucks on the floor right with Radix blowers on them and they come with a factory warranty. A truck and an Avalanche.
The blower system has no real guts though. Same blower as a Radix but with 5.3 injectors and fuel pump, and only 4.5 or 5 pounds of boost and the tune is very conservative. The pulley is pressed on with a non-removable fit so changing it requires a full nose piece change.
The Radix we would buy from magnacharger has the 8.1 motor injectors and fuel pump and 6 or more pounds of boost and a more aggressive tune. And you can remove the pulley for an easy change.
Thanks, therock

FYI, I am a member of LS1Tech - Truck Performance Section. And GM Performance Forum.
If you folks need help come on in. Lots of knowledge there. The latter one has been around a very long time.

Thanks
