Gents,
Thought I'd share some results from an awesome setup LG put together for a gentleman with a brand new C6 straight from the dealer.

Modifications:

E-Force Supercharger @ 8.5psi
LG G9X2 camshaft
Ai 275cc GM LS3's (http://www.advancedinduction.com/LSX/AiLSx280ccGM821Head.php)
Akrapovic stainless slip-on exhaust

All testing is done with 92/93 octane pump fuel.

Final #'s vs. Stock:

As a reference for how much difference a good top-end can make, this is a graph comparing this new setup to the customer's previous C6 GS with the same supercharger on the same fuel & boost with a lesser heads & cam setup.

Awesome results, Phil! Power everywhere. I know it has the slip on exhaust but I didn't see anywhere in the threads if it had longtubes on the car or not. Did LG stay with the mani's or go LG longtubes?

I went by the details LG posted in the corvette forum thread I linked. I'll have to ask for confirmation :)

nice numbers. So with the other head cam setup was the same pulley size and everything used? both at 8.5 psi? only reason i ask is even stock ls1 heads it doesnt take much to make 650 rwhp with boost. But if each setup was making 8.5 psi it makes sense as the good heads are going to make way more power at the same boost.

Same boost pressure, same blower/IC setup, etc. :)

I haven't been on in awhile, I'll have to ask Anthony if they've got video of this thing yet.

So its the same boost pressure but on a slightly smaller pulley, correct?
