This is the ultimate cooling solution at the most affordable price, no more paying for a fancy name and spray painted letters when you can have the best for less. When dealing with Roots or Twin Screw Superchargers there's always the issue of intake temps. When running the car hard and spinning the blower fast you create heat. Heat equals a loss in power as well as the possibility of damage to the engine. Whether it be on the street or at the track the warmer the car runs the more timing gets pulled. In addition to that an excessive amount of heat known as heat soak starts to take place. This keeps the car down on power and running less efficient.
