During development of AWE high horsepower turbos kits for the 997TT, AWE experienced excessively high intake air temperatures. Upon close examination of the stock intercoolers, AWE found they matched the same specs as the 996TT X50/GT2 design, which is suitable to 600hp, but not much beyond that. Since an OEM option was not available, and AWE power goals were well north of 700hp, AWE undertook the task to construct a completely new intercooler system. Compared to stock, AWE cores are 37% larger (422 cubic inches vs 308 cubic inches). In contrast to the stock cores, AWE are a high flow bar and plate style and are built to our charge row and fin count specs. These specifications resulted in improved intake temperatures by a massive 55F and improved drop pressure resistance through the core by 1 psi. Considering that extremely little trimming is involved to fit such effective units to the car, this is a huge engineering feat. In addition to the superior core and end tank design, the AWE kit also features 6-ply silicone hoses with gentle curves to prevent bursting under pressure. They are attached to the intake and turbos by stainless steel high force t-bolt clamps, and a molded lip is integrated where the hoses meet the turbos to imitate the factory locking mechanism. Further, AWE hoses use a Nomex braiding for superior strength, instead of more common polyester. The very best materials and industry-leading engineering separate this kit from all others on the market. Whether you are simply running enhanced software, or are planning on a larger turbo upgrade for your car, AWE intercoolers solve all heat-related issues that come with more turbo boost. Keeping your intake air temperatures low results in more power, better engine output stability when outside temps climb, and the safety margin needed when pushing the limit. Please note, the AWE Performance Intercooler is for racing use only.
