First who mounts a supercharger below the intercooler on a V8?

Secondly it looks like a ProCharger type blower in front of the left side cylinder head.

I agree - look at the accessory belt width on the passenger side, then the wide belt on the dvr side looped around some sort of supercharger. I would prefer an actual screw charger for shear grunt v. a belt driven turbo, but it is definitely the way to get the tight package.

Intercooler before the charger, what a moron that guy is. But, HEY, WHO BROUGHT IT TO YOU FIRST??

Maybe even in a 2nd gen. too huh Damn

It looks like they took alot of the design ideas from the supercharged northstar engine that is in the XLR V's

It's a twin-screw supercharger.

The blower pulley can be seen on the image that just depicts the intake/heat exchanger unit (it's at the bottom). GM are utilizing a system very similar to what's on the S281-E mustangs, where-in the supercharger is slung underneath your "intake" and the hot discharge air is blown up through the heat exchangers and then down into the cylinder heads on either side.

Your collective silence speaks I think. C'mon, dudes, lay your jobs on the line for us man! We'll promise it will stay between the 1,000's of members here.

The LS9 uses the largest blower ever built to date by Eaton. The supercharger is a 2300ci unit. The 1900ci unit that was tested on the LS2 put out over 700 hp with something like 8 psi of boost. The LS9 made in the neihborhood of 900hp on pump gas with a 50 state legal emissions tune. This thing should be a MONSTER if GM allows it to be. Only time will tell. And you can bet it won't be advertised with the figure listed above, but it is capable.

uh yeah, my bad I went back to pg1 to hit the link and saw the third pic posted again, with the more than obvious pulley. Looking at the engine shot I thought it was an idler, but seeing that makes it obvious and yep, just like the Fords. Good eye. I thought the pulley driven "charger" looked damn small but I just took that ball and ran with it anyway.

Sorry, I'm such a shat stirrer!!!

Yea, too bad the C6 Z06 smacked around the Viper in almost every single catagory.. lol

That is true. I cancelled motor trend because a viper and z06 was on the cover 6 months in a row.

hahaha.... Amen to that! Poor Viper just got ahead for 08 too but now back to the drawing boards for SRT... The 08 Viper is a badass car but, LS9>Viper.

Nice thing is I'm sure LS9 components can be used on all the LS based engines.
