Performance without compromise. That is the goal we set for each and every product we design and manufacture, from exhausts to complex turbo kits. We strive to develop performance products that enhance the driving experience with none of the ill effects that come from improper engineering.

Our 650S package is our intermediate Porsche power offering, and fits the needs of most 997TT owners out there. Further, this package can be a logical stepping stone to our acclaimed750R Kit , as all of the components can be reused at that next power level.

Highlights of this kit:

• AWE Tuning 997TT Muffler with German HJS Catalysts
• 321 Stainless Steel AWE Tuning 997TT Headers
• CAD/CFD Developed AWE Tuning 997TT Intercooler Kit
• Large Bore AWE Tuning 997TT Throttle Body
• Proprietary G.I.A.C. Software with Optional Handheld Switching Feature

Proprietary software developed jointly with G.I.A.C ties our cutting edge hardware together into a complete package. Our G.I.A.C. software catapults our kit to world class status, and we are the only 997TT power package in the world to feature the ability to switch between software programs on the fly.

By use of an elegantly simple handheld device, you can choose different power profiles. Did you fill up with high octane race fuel and want to unleash this kit's full 700hp potential? Plug the included handheld switcher into the port under the dash and push the race button. Are you leaving your car with a valet? Push the Valet button and you've instantly detuned the car to a mere 50hp! Concerned about security? Press the Kill button, and not even your own key will start the car until an alternate operational button is pushed. How about stock-like power levels for when you lend the car to a friend or are dropping it off for dealer work? Push the stock button and the car is back to showroom floor power levels. This is the ONLY 997TT power package in the world that can boast such technology! See a demonstration video below:

Optional G.I.A.C. Software Programs:

• 100+ Octane Race Fuel (700hp)
• Valet (30 mph speed limiter)
• Ignition Kill Security (no start antitheft)
• Low Boost/Power

Knowledge gained from doing software tuning as a technical partner of G.I.A.C. demonstrated that a freer flowing muffler was mandatory for this power level. Our not only maximizes power, but also sweetens the sound of the 997TT's flat six. Additionally, our system utilizes German made 200 cell high flow catalytic converters so your car can enjoy a horsepower increase without any Check Engine Lights. Our straight through design uses very advanced sound packaging materials and single muffler enclosure that eliminates drone at cruising speeds.

During development of this kit it became quite apparent that the stock exhaust manifolds would not be up to the task of producing 600+ horsepower. We carefully studied the available space and used advanced CAD modeling to engineer primaries and secondaries that would deliver an excellent balance of quick turbo spool up and massive high rpm flow, as well as perfect fitment. Our 321 Stainless Steel 997TT Headers have been extensively street and track tested and have proven themselves to be the finest headers available.

However, the combination of the increased boost from the turbos and increased flow from the headers proved to be too much for the stock intercoolers. We then set out to develop an intercooler system that would allow us to achieve our horsepower goals while keeping intake air temperatures within a safe range for the engine. Our 997TT Intercoolers feature cast end tanks that were designed in house using sophisticated CAD (Computer Aided Design) and CFD (Computational Fluid Dynamics) software. Our intercoolers are not only 37% larger (422 cubic inches vs 308 cubic inches) but they also drop air intake temperatures by 55 degrees Fahrenheit and improve pressure drop resistance through the core by 1 psi. Unlike other kits on the market, We designed our intercooler system to be a direct bolt in piece, meaning no permanent modifications need to be made to fit them to your car.

Our large bore throttle body assembly from our 750R kit is also used on this power package. During thorough research, a larger throttle body assembly was created which removed a bottle-neck that was hindering airflow into the combustion chambers. After various CAD revisions, our final design, incorporating a CNC machined Throttle Body adapter, is 10% larger than stock and allows for a significant improvement in power over the OEM part, which allowed us to finally achieve our power target.

Please note: use of our turbo kit requires a US spec aftermarket performance muffler to be fitted in order to keep turbo temperatures within a safe range. Our kit cannot be used with the stock or European market muffler due to their restrictive natures. Also please note that with aggressive driving, a Sachs/AWE clutch kit is recommended at this power level.
