454 LS7 2010 Camaro SS Dyno Numbers! Finally got time to dyno our 2010 Camaro.
HKE 454cid C5-R Block 11.4 compression
238/251 115 LSA Cam
WCCH LS7 Heads
Ported LS7 Intake Stock 90mm TB
Kooks 2" Headers and 3" Exhaust
Roto Fab CAI
These numbers are with the stock balancer. Im still getting quite a bit of restriction as the MAP pressure is still dropping to 95 above 5800 rpms.
Up next 25% UD pulley, FAST LSXr 102mm Intake and NW 102mm TB.

i willing to believe the factory cai intake its killing the power as well, that sharpe 90 of the tb is not good for power, i remember in my 05 gto when i had my 438 stroker with ls7 heads, i picked up 20rwhp from ditching my k&n intake to an custom over the radiator intake

I am going to say this 3 times: WOW WOW WOW !!!
Can't wait to see the numbers when you have the restriction issue on the intake side corrected. She's definately exhaling nicely with the 2 inch headers !!! Got any idle or rev vids ??

The HSV W427 (Kind of a G8 with LS7 in it) runs an otrcai from factory.

I could make a lot more power with a larger camshaft. We install larger cams in almost all the LS7's we do. But all out rwhp was not the goal of this setup.
I wanted to make big power and tq but still retain stock like driveability. I can cruise @ 1200 rpms with little to no cam surge. It idles @ 850 rpms. And the exhaust is fairly quite. If I want to drive a big cam monster thats loud as hell! I still have my vette.
I have dyno videos and I going to get some flyby's in front of the shop tuesday.
