Cool Power

Are You Wasting Horsepower?

Thermal management technology has evolved to an art. Enthusiasts everywhere are realizing that potential
horsepower and reliability gains are significant and are worth far more then their cost. Auto manufacturers go to great
lengths to reduce heat radiation from exhaust and turbo systems on to the surrounding components. They use multi
layer heat shields, reflective barriers and even ducting of air. All manufacturers agree that proper shielding of radiant
heat is extremely important. Any vehicle can benefit from this technology, especially high performance and racecars.

RX7’s with single turbo setups seem to gain the most from this technology. Instead of just wasting some horsepower, with the rotary it’s easy to waste engines. Since most aftermarket single turbo kits do not come with heat shielding and most installers don’t spend the necessary time to build adequate shields, this leaves exposed radiant heat to blast the lower intake. On 3rd Gen setups it usually favors the front runner, this superheats the charge for the front runner just as it enters the port, not only does this raise the charge temperature in to the danger zone, but makes you think the engine is running rich, “tuners” unknowingly lean the overall mixture to compensate, but then the cooler rear rotors is dangerously lean. Also the air temperature sensor is located upstream where the temperature is cool, therefore; you would never know that radiant heat is causing this mixture imbalance and robbing horsepower and reliability. 90% of the FD single turbo engines we open have rear rotor failures which further attests to this condition.

Are you wasting horsepower? Pettit Racing is producing new Cool Power Thermal Management Systems designed
to fit most RX7 single turbo kits. These kits are easy to install and the benefits are priceless. We also have a kit for the
factory twin turbo setup as well. The new Pettit Racing Cool Power Kit uses the latest proprietary technology for thermal protection. These materials do not emit or expose the driver to harmful substances. The Thermal Barrier Panel or “TBP” is made from non-woven thermal insulation and is created specifically for use in areas where minimum space is available. The Thermal Barrier Wrap or “TBW” is made of woven thermal insulation, both types resists temperatures up to 2000 degrees F. Both materials contain no asbestos, are non flammable, will not corrode, and resist mildew and deterioration.

The Cool Power Kit for single turbo setup includes:
A custom Thermal Barrier Cover, fits around the turbo hot section, it is reinforced with inconel wire, assembled with
stainless steel staples and has proven to be a very durable and long lasting part. A stainless steel heat shield, fits between the lower intake and the turbo system, is layered with thermal barrier panel. The simple design retains an air space between lower intake and shield, further reducing heat transfer. 15-foot roll of Thermal Barrier Wrap, “TBW” for the down pipe with enough material to wrap front section of the mid pipe. 2 Thermal Barrier Panels, “TBP” are precut for the floorboard area just above the hottest section of the exhaust system and are designed to reduce heat transfer in to the passenger foot well and floorboard area. This can make a significant improvement in occupant comfort level.
2 feet of hi temp metal tape, which is used to seal the panel edges. 3 Stainless hose clamps to secure the wrap.
