TSP Cam'ed Camaro

I finished working on my buddy's 2012 Camaro SS. He wanted to try to get 500 whp out of a cam only so we will see how close we get. Our dyno appointment is March 1st, Friday.

Mods:
Texas Speed 235/239 .639 .623
PRC .670" Spring Kit
Texas Speed 2" Tube Headers Off Road Extentions
Borla 2.5" Cat-back
Fast 102 Intake Manifold
Stock Throttle Body
Roto-Fab Dry Intake
160 degree Thermostat
Bocsh 80lb Injectors
e85












Start up video isnt the best quality since all we had was a go pro and a phone and it was in a small garage so the sound is a little off.

http://youtu.be/sjZELy2o0Qg
Video is uploading right now so it may not play









E70 we will retune and shoot for 500rwhp on real e85
This is a eddy current dyno NOT and inertia dyno.

Sweet build man i would have worked on the heads rather than the fast i think it would be money better spent as the ls3 manifolds flow pretty well and the fast is pricey but it looks killer. Hope you make your goals With the lift on your cam i would recommend aftermarket rocker as it has been mentioned that the stockers max out at 625 lift the geometry is wrong with lifts higher than that at a minimum i would do the trunnion upgrade just my thoughts

TB and 2.5" exhaust going to hold it back a few horses. I predict 485rwhp, considering the big headers, fast, and e85. Few extra ponies in the crank pulley too if you swapped to an underdrive

We will be doing heads on it within a few months then we will upgrade. Otherwise i would have recommended it now.

I have never seen a throttle body add hp on a dyno so i wasn't going to waste his money on one. 2.5 wont hold this car back at all, hell i even run 2.5 on my 714 whp cobra.

From experience the 2.5" exhaust will hold back power.TB is good for 5-10hp too if the cold air can flow it.

good choice on parts. did you get the scoop and washer bottle relocate for he rotofab intake?

question on the cam...why did you choose such a long duration? the poor heads and its internals wont benefit or like above 600

No we didn't get the scoop or washer bottle relocate.

This car will be getting heads in the near future. So no reason to swap cams twice.

Care to elaborate?
Have to remember a 90mm throttle body will flow 1200 cfm and a 105mm will do 1500 cfm. A fast will only accept up to a 102mm is stock forum.

Even on a 100% bolt-on car, you are leaving power on the table with the 90 vs the 102, regardless of any cfm equation you can come up with. You will see manifold vacuum with the 90 over 6000 rpm, guaranteed.

This isn't a 4.6L cobra. (which would ALSO gain power going to a 3" exhaust)


Don't mind me, my n/a car makes well over 600 through an automatic.

If you're looking for 500 RWHP on that setup, I'd put my money on disappointment.

I was basing my comment off of your original post. But if you are just looking for more and not aiming at 500, then you should be happy. I'd guess in the 445-455 rwhp range, maybe less.

Since your on e85 it may pull it off on a good #s dyno. 480hp is my guess.

Well since our awesome e85 is barley e70.
We kept the power at 490 whp and 455 lbtq on a loaded dyno.
We will dyno it again for the 500whp when we have better fuel.

Never thought e85 would give that much power. You got the chart?

Automatic + L99 on his car.
That's more loss in drive line and less power in the heads.

I doubt the fast intake with stock TB is adding much.

Which means I could put down 500+ on e85? I bet I could nail 600 on the right dyno....
