From the laws of Physics, we know that cooler air is denser than warmer air, and since horsepower increases as the amount of air and fuel burned increases, cooler air makes more power. Replacing the factory thermostat with the Hypertech low-temp PowerStat will allow the engine to run cooler, making more power and reducing the engine's tendency to detonate. Detonation, usually producing audible pinging or even knocking sounds, refers to the spontaneous explosion of the unburned air/fuel mixture in the combustion chamber. Detonation violently ends the normal combustion process, reduces power, and can severely damage the engine.
Hypertech Cool Fan Switches are designed to be used with our Power Tuning products for increased horsepower. In some vehicles, the electric cooling fans are controlled by the computer chip, but in others, the cooling fans are controlled by the fan switch (which is usually set to turn on at about 220F). TPI-equipped Chevrolet engines that have two fans use a fan switch for the second fan, and the first fan is controlled by the computer.
