Stock Dyno 276 at the wheels?

So I am getting my AWE exhaust installed today and I got my car dyno'ed before. They ran it twice and got 276 at the wheels. This seems high to me but I am definitely okay with it. I will post the results once it is finished to see what the gain is. Just wanted any input as to possible reasons this could have come out this way.

Porsche is nice as the HP that they quote is the minimum that the engine will make usually a little more but they do keep it close. Just look at the Mustang Cobra when it was making a lot less than they said I think they replaced the engine or something like that.

I wouldn't put too much "stock" in absolute values. The meaningful number will be the delta with the AWE exhaust. Am looking forward to the numbers post install, please post chart if you can so we can see across the rev range.

Yeah the number isn't as important as the delta, that is a little "high" but within the realm of possibilities, again let us know what the delta is.

Mine dynoed at 275hp @ the rear wheels at Imagine Auto, with a Mustang Dyno. However, I didn't get as high of gains after tuning as some did. 283hp ar the rear wheels with GIAC and EVO intake.

So it was actually 278 before the exhaust and 287 after the install. The most gain is after 5000 rpm.

You did catback only right? Your gains are they averages or peak of best run before best run after or average of runs before and average of runs after? Either way you got about 10hp gain which from a catback only is about right.

Yea it is catback only. The results were the same after multiple runs before and after, so just used one run before and one run after.

Wow. Drivetrains pretty universally sap 15% of hp. 275 rwhp works back to 323 hp at the crank. Is that what we really have? I've read R&T where they figure Z06's actually make 530 at the crank based on the same analysis.

SAE Corrected?

If so that is impressive.
