We've been hard at work testing some reliable performance upgrades for the Porsche 997TT platform. We have completed our exhaust manifolds (headers) for the 997TT, and saw gains of 8 wheel horsepower, or ~10 HP at the crank. Dyno sheet below including GIAC chip and our in-house built A.W.E. Tuning performance exhaust system:









Last week we bolted on our new larger AWE VTG turbos. Utilizing a brand new proprietary GIAC development file at 1.1 bar boost we saw an additional 35 wheel HP on pump gas, putting us at 553 wheel HP, and we're just starting with the tuning. Here's a dyno showing the above set up with the addition of the AWE VTG turbos. It's important to note a few items - These turbos maintain Porsche's VTG technology, and are a direct plug and play modification.

Also note that all our testing is being done on PUMP gas, and that we prefer to look at WHEEL horsepower numbers as crank numbers can vary substantially depending on the baseline chosen to determine the crank HP correction factor.









Project 700S is a straight forward project - we are looking to hit 700 crank horsepower on pump gas for Street cars. We are running into a few hardware challenges during development, but the power at this stage is phenomenal - we're already making 53 wheel horsepower more than our popular 996TT Porsche K24 kit put out on pump gas. Intercoolers will be examined, and GIAC is currently rewriting the software program to take full advantage of the AWE VTG turbos. The current program only makes 1.1 bar, our new proprietary GIAC software program will push boost to 1.4 bar at higher rpms, as well as increasing the torque figures.

We expect great gains across the board from this setup once the hardware and software tuning is finalized. We'll keep you posted with new dyno sheets as we continue our development work with GIAC.

All this power has forced us to reexamine the factory suspension and brakes. Luckily for us, we have direct relationships with all the tops names, and work directly with their engineering departments on Project 700S. Because of our great success with the brand on the 996TT platform, a Moton Clubsport coilover suspension was chosen for the car and installed two weeks ago - as far as we know, and according to Moton, the first in the country on a 997TT. Specialty parts to mate this kit to the 997TT were designed and machined in house, and the factory PASM system has been turned off via the Porsche PIWIS scantool. Our Motons are coupled with H&R springs, a natural choice given our 9 year partnership with H&R.

 

While the stock brakes on the 997TT are some of the best on the market today, we wanted more. We prefer Brembo on Porsche cars, as nothing beats the pedal feel of these kits. Looking for the ultimate deceleration upgrade, we went a step further beyond the standard Brembo GT kits and installed the GTR brake kit front and rear.









Stopping power is absolutley unreal, exceeding the gripping ability of the Michelin Pilot Sport Cup tires currently on mounted on the BBS Motorsport wheels.

wow! that is one badass tt! The combination of those components must be phenomenal! One question, who is producing the new turbos for you? This is the first I've heard of a VTG turbo replacement.

 

Joint venture between us and Borg Warner.

 

Nice numbers Mike, congrats!!! I knew it was only a matter of time before you guys made this chassis even better with mods. I can't wait to see what the future holds for this platform......

 

Alan-

Thanks for the kind words.

It's only going to get better. We have yet to really tap into these new turbos...

Stay tuned.

 

Holy sh*t Mike. The special sauce sure looks good!

 

The Performance Gains Are Amazing, Im Glad You Guys Include Dyno Resluts Unlike Many Other Tuners.

Good Work Guys

 

wow u guys are doing a hell of a job.... nice write up also...... i cant wait to see one of these things perfrom.... great work guys

 

Thats AWE-Some guys. Keep up the good work. Hopefully by the time I get my 997TT you guys will have an 800hp kit available.

 

Nice work! I have a feeling that car will exceed even your (A.W.E.'s) expectations with the quality of parts and testing/tuning you will be doing.

 

9ff seems to have some replacement VTGs as well....though after the horror stories here a few years back, I would not go near them

Keep up the good work Mike. opefully project will be done just in time for me to get my 997TT (waiting for damn PDK, aerokit and X50)

 

What is the approximate size of the stock VTG compressor? your upgraded compressor? how does it compare to the K24? the GT28?

 

Awesome job and thanks for posting. I got a chance to check out the car last weekend in Philly and boy oh boy was it looking amazing. Love the selection on modifications performed as well. Best of luck with the tuning.

 

Nice write up Mike! And congrtas on the progress
