Hey guys, got this months CHP and guess what's inside........this intake. Edelbrock list these gains:
I quote:
Edelbrock's been at it on the dyno with there new intake manifold and 90mm tb for the LS1. Compared with the the stock LS6 intake on the company's 5.7L LS1 Corvette ZO6 engine, the Edelbrock combo allowed amounts of air with the larger plenums and fuel with the tb to enter the engine.

Before:
Max power:447 hp @ 6,500
Max torque:428 lb-ft @ 4,500
Average power:347 hp
Average torque:396 lb-ft

After:
Max power: 483 hp @ 6,498
Maxtorque: 431 lb-ft @ 4,993
Average power:347 hp
Average torque: 400 lb-ft
Difference: +36 hp; +3 lb-ft

Ready for the damage..........................$835 for the combo as per Edelbrock Corp.

I did post in the LS XT thread that Richard started but I didn't think some of you guys would see it so I made it a little easier for viewing pleasure......LOL.

looks like it probably lost quite a bit down low as the avg hp stayed the same and the peak torque moved up.
