OK, here we go. I just returned from Farnbacher Loles where Kip pounded my Cayman on their dyno once again. First, some of the details.

My Car: 2007 Cayman S
Mileage: 10,181
Gasoline: 93 Octane [R+M/2]
Dynamometer: Dyno Dynamics sustained load, climate controlled
Engine Mods: None
Exhaust: Stock Headers with A.W.E. Tuning Catback


Baseline Tests:
(taken in January when my car was completely stock):

Stock RWHP:



Stock BHP:




A.W.E. Tuning Tests:

A.W.E. Tuning RWHP:



A.W.E. Tuning BHP:



Gains:

BHP Gained: 19.4
RWHP Gained: 17.1

Yup. That's right. 19.4 BHP gain....! As soon as I drove my car I knew this system was delivering more than previously thought. The car simply rips. If you drove my car, you would agree. There is no way that's an 8-10 hp gain. It's way more than that and the dyno agrees.

Kip did about 12 runs over the course of an hour. Some cold, some hot. The tempurature in their climate controlled room is the same with small differences in barometric pressure and relative humidity from last time (differences that would likely reduce power output). The shortest run was 307 BHP. Then 309, then 311, then the car consistently spit out 312-313, over and over.

I forgot to ask Kip for the overlay between baseline and AWE. I'll give him a call and see if he can send one to me. I'd like to see that because interestingly, the AWE seems to hit harder in the mid range than the stock.

OK, go ahead. Discuss........

Thanks GB for the detailed analyzes, it’s good to get some definitive results from a singular mod. The bad part is I may have to put the A.W.E. exhaust on my wish list. Sounds like it would complement my recent Softronic upgrade.

Very impressive. Thanks GB!! So when you adding a Softronic Plenum.

Great review, definitely on my list of exhaust options.

Sigh I used to work a 1/4 mile from their facility in PA. Did not own a Porsche then..

GB, I was just watching your U Tube video of the Borla exhaust tonight trying to make a decision on which system I would like to get. I was a little concerned about the resonate rattle I could hear, it sounded like your number plate. Anyway, now I'm waiting for another U Tube clip with the AWE exhaust.. don't make this easy..

Are you going to make the ALMS race at LRP ?? If so, I'll see you there..

Great, but when you get 300 RWHP, THEN you can really see what the Cayman can do.

Unfortunately not. I have to be in LA for business....

I can only imagine. I feel my car is pretty strong as is.

What's the max gain in torque? It looks like the low end dip in torque has been smoothed out with AWE.
