Product Description


From the laws of physics, cooler air is denser than warmer air. Since horsepower increases as the amount of air and fuel burned increases, cooler air (with more air molecules per cubic inch) makes more power. The PowerStat allows the engine to cool down to a lower temperature than the factory thermostat to make more power. At the drags, water can be sprayed on the radiator between races to drop the temperature and improve performance, but the PowerStat ensures that you leave the line at the same temperature each run to give consistent maximum performance for bracket racing.

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 abruptly and violently ends the normal combustion process, reduces power, and can severely damage the engine. A PowerStat reduces the temperature of both the incoming air/fuel mixture and the surfaces of the combustion chamber, greatly reducing the tendency to detonate, and allows the engine to safely develop more horsepower.

NOTE: Gasket not included.

Reviewer: Jake S (WPAFB, OH)
Keeps my engine running cooler which I enjoy, The only thing was it would have been nice if they would have included a new spacer, but instead I just had to use the old one from the old T-stat.

Reviewer: Joe L (salem, WI)
I had problem with over heating and the engine just not having any kick in it anymore. I put the 160 degree and it has worked great, I will do the same for the rest of my cars. Word of warning you might want to hang onto you old one just in case for winter if you aren't getting enough heat into the motor. I am running it as 160 for now and I have had no problems but I might get the 180 if problems happen. First mod, very easy to install but I have more to go but this is great to do even if you just want to keep it stock cause it will help the engine live longer.

Reviewer: Laura M (Annandale, VA)
This is a nice upgrade to the Grand Prixs. Especially if your planning on doing any kind other kinds of mods to the car. This is a easy modification, and not an expensive mod either.
