671 rwhp from LS3 with 8.4 psi of boost and EPP Blower Cam - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

Exotic Performance Plus · 12-02-2009, 06:03 AM

LS3 with long tube headers and exhaust, our EPP blower cam, and 8.4 psi of boost from an ATI ProCharger D-1SC. Keep in mind this is rear wheel horsepower, and is from our conservative Mustang Chassis Dyno. This was with a lot of timing being pulled out of it, as it is a stock bottom end. Bob

Good work guys..can I see a dyno graph?

the rich dude · 12-02-2009, 11:44 AM

Nice job! What octane fuel were you running?

Andro · 12-02-2009, 11:45 AM

Nice

Mike TexaSS · 12-02-2009, 12:05 PM

Nice. Fuel system upgrades?

JANNETTYRACING · 12-02-2009, 01:58 PM

How come the Dyno Sheet Says Engine HP not RWHP.

navyblueSS · 12-02-2009, 02:53 PM

Nice work!! Stout numbers!

Good point Ted. Do you suspect the software has already added the 15% loss?

Codefive · 12-02-2009, 05:50 PM

Sorry ... I gotta call

on that one.
I can believe flywheel HP but not RWHP.
If that were accurate, than that car should run 10.20s @ 130 MPH at 4000lbs
Bring back a time slip.
There's just too many of these out there making similar numbers and yours is 15-20% higher than everyone elses???
That must be one "magic" camshaft.

If you let the engine breathe, you can make big power on less boost. Boost is a measure of restriction....not a measure of power. These numbers are very believable. I make similar power on 8.5psi of boost in my TVS blown vette.

Sounds inline to me. Was this a C6 or a Camaro Bob?

The above dyno graph shows the same thing. It is indeed rear wheel horsepower. The dyno graph above is from a Cadillac CTS-V that has also been on another chassis dyno. It gave similar results on the other dyno and to date is the highest recorded horsepower they have had on thier dyno. Here is a link to this CTS-V. http://www.exoticperformanceplus.com...Car.php?car=29 We started with a new LS2 block on the above CTS-V, added a 4.00" stroker crankshaft, the same EPP camshaft, off the shelf AFR 225 heads, and a FAST 92 intake manifold. We used a ProCharger F-1A.

The LS3 heads flow 330 cfm right out of the box, with boost and a good camshaft the power output is always much higher than what we use to see with the LS2 engines.

Thanks, but this is a Corvette. Same basic type of drivetrain losses as it also has an IRS rear.

I agree, and I know you've been around these engines long enough to know what can be had out of them. Thanks.

Thanks, I know you've made a lot of power with these engines too. This is from an 2008 LS3 Corvette, so the drivetrain losses should be about the same as in the new Camaro. Here is a link to this Corvette. http://www.exoticperformanceplus.com...Car.php?car=59 Bob
