Hello,

On Friday October 10th a 997 GT2 was handed to us by a gracious customer looking for added performance. In this thread we will document a comprehensive case study. Our mission is to further prove that nobody takes product development as serious as we do.

As I am sure many of you know, the headers and intercoolers are the same as the standard 997TT. Incremental testing of our A.W.E. replacement components (headers, mufflers, intercoolers) will be done on our Mustang Chassis Dynamometer to show what further gains can be had.

Here is the car as it was delivered to us on Friday.







Currently the car is on they dyno for baseline testing. We use a variety of scan tools for data collection:

Porsche PIWIS Tester
Durametric
Custom G.I.A.C. scan tool

Data points reviewed:

Ignition Timing
Injector Duty Cycle
Boost Pressure
Knock Activity
Air/Fuel
Exhaust Gas Temp.
Intake Air Temp.
Vane Regulation
Mass Air Flow - Grams Per Second
Fuel Pump Duty Cycle
Fuel Pressure
Throttle Position




We hope you enjoy this thread. If you have any questions, please ask. We will update as often as possible.

-VIDEO COMING SHORTLY-

 

Subscribed! I'm definitely looking forward to learning more and seeing what you guys can get out of this beast! Keep up the good work! Do you have any HP or performance goals that you're trying to reach?

 

this will turn into a real monster

can't wait to see the results

 

Nice Mike!!! Need to slap some clear corners on that bad boy.

 

very interesting..........
Will see what you will find according to the all temp.....

 

Sounds good. We wait updates

 

GT2 looks great in GR...looking forward to the progression

 

Oh my...this is going to be awesome!!

Mike, you should test intake system. There is some guy saying that 997 tt plastic intake system works better than original GT2 one in 997 GT2.
I have the one from GT2 in 997 TT but I'm not so sure because I made to many different things same time.

 

the GT2 intake system is designed to produce a pressure drop of 0.2 bar across the plenum. It does this in order to further cool the intake charge, but the Gt2 turbos have to hit 1.4 bar to get 1.2 bar at the motor. Hitting 1.4 bar over heats the intake charge, so you are adding more heat at the turbos to compensate for taking heat away at the intake. Seems like a wasted effort to me.

Since the Gt2 uses the same intercooler as the TT, an improved intercooler should drop the IAT and make the added pressure drop (and intake) unnecessary.

 

True! Bigger should be better in this case.

 

Beautiful car.

Mike - Thanks for keeping us informed on your progress.

 

Here are a few more photos. We have compiled some very interesting data which we will be posting shortly.

So after we did our baseline dyno runs, we rolled her onto the prototype list for a futher look.




We began taking things apart and seeing what we can improve.





We fitted one of our standard 997TT mufflers to see what a proper exhaust will make on the new GT2. We then did more dyno pulls.






Stay tuned....

 

My pleasure...
