I bought this car on the 17th of December 2011. It is a 2008 six-speed with factory npp exhaust. Posting it incase anyone is in the market or interesting in a C6. Dyno numbers aren't everything but it was cool to see what kind of power it makes before I start modding it. I'll take it to the track sometime soon.

Wow, 408 bhp at the wheels? That's impressive!

Rebel 1

Like it!

thattexaskid19

how sure are you that its stock...?

I'm not sure if "bhp at the wheels" is a correct way of saying it

408 rwhp is a great number to start at!! It took me a lot to get there in my ls2 a6. Congrats!!

Either a happy dyno or uncorrected numbers. A completly stock ls3 doesnt make 408 rwhp.

Very generous dyno.

TurbosNv8s

what was the ambient air temp? what is the elevation of the dyno? What brand dyno? Lots of factors that can swing numbers. That being said, if you plan on modding it and using the SAME dyno you should be able to see accurate improvements. Only changes then would be air density and temperature.

I thought it was common knowledge that a stock ls3 puts out "about" 365-380 whp

davidtcpa

I think that is about right.

Our 09 A6 put down 377

Yea, something does not seem right. I have an 08 manual with LT headers, Custom ECS tune, Callaway CAI, 160 t-stat and polished and ported TB and I put down 424 at the rear wheels. My stock numbers were ~375. I think either it is a very friendly dyno, uncorrected or work has been done to this car.

I have seen several LS3 manual transmission car put down 390 +/-RWHP in Dynojet Dynos. Our Corvette Club conducts an annual Dyno Shootout every December. http://www.vegasvettes.com/Events/20.../1112Dyno.html An LS3 dry sump Corvette dynoed at 403 RWHP and 392 TQ (factory tune). That surprised most of us. The other Corvettes dynoed within their expected range, so I don't think it was a happy dyno. There was a lengthy discussion in the general Corvette Forum section about the LS3 dry sump hand built engines. Do they produce more HP and if so why? better built, the dry sump, or a combination? http://forums.corvetteforum.com/c6-c...lt-engine.html

Yes it is stock. All it has is the factory npp on it. This isn't my first rodeo with LS cars so I know when one is stock. Standard correction the hp number was 416. These numbers are SAE corrected. I'll post the dyno sheet for the doubters.

Here you go guys. Hopefully you can see them.

Put drag radials on it and take it to the track. The dyno is just a tool and nothing more-the track doesn't lie.

Turbo6TA

Yup .. And SAE Corrected (SAE-J1349) should be the only numbers that anyone would care about regarding a dyno pull.

SAE Corrected makes the playing field all the same no matter how hot or cold the ambient conditions are, or how high or low you are in altitude.

About the only thing that mucks-up the numbers is what type of dyno was used ... "Mustang" dynos seem to always show lower numbers than the "Dynojet".

JUIC3D

Dynojet numbers can still be skewed though. The weather station can be tricked with hot air from a blow dryer and/or a damp rag.

I'm not saying any of this happened, but just because it says "SAE Smoothing: 5" in the corner does not remove the scrutiny of the unusually high dyno numbers.

Again, take it to the track and post up with how it does. I'd love to see it
