Any chance GM comes up with some more mods. stage upgrades, or better yet a new supercharger stuff that will still keep warranty?

 

I doubt it, the turbocharged Cobalt is probably going to be their priority for stage kits.

 

Thats what I figure, but also what I fear.

 

hey, where you at in WI ??

 

Appleton, yourself?

 

I grew up in Jefferson, WI

 

nice. i was born in beloit. what pulley would go with my stage 2 that you make? i have no cooling mods. do i need hc or something if i went with 2.9 or 2.8. and also, what gains would i see vs. the pulley i have now??

 

Most people go with a 2.9 if they don't have any other mods as it works quite well with the rich stage 2 tune.

You should see approx. 1.5 lbs of boost and it should spin up a little bit faster since it's quite a bit lighter than the steel stage 2 pulley.

I wouldn't expect GM to come out with any other vehicle or any kind of mod for the LSJ ever again...

 

**Fingers Crossed** expecting a wheel hop package to be coming out this summer.

 

Grew up in Janesville where GM builds the Suburban and Tahoe.....now live 15 minutes from Dubuque, IA

 

You're only 15minutes from Dubuque, IA thats funny. I am in the quad cities in IA about 20minutes from Davenport. We should get together and cruise sometime =D.

 

What do you charge for one? does that void my warranty? Only 8,000 miles on my car. Also, do you just swap the pulley? no other modifications necessary?

 

73 mm was the gm stage 3 pulley i beleive
nates stuff works well thats the easy part just buy the parts from Nate! tunes are the issue hard to get really good tunes and without proper aftercooling its all moot
