Thread: 180* T-stat

When I drive my car to work, I don't race there. I drive 100 miles a day. I get in the car, relax and drive. I don't speed. I don't beat on my car, etc. When I do race, I do so at the track. If I am going to the track, I will do a bunch of things to my car to prep it to race. Remove weight, change tune, change t-stat, etc. I mod my car so that I can have fun on the weekends at the track. But I de-mod my car during the week to save fuel.

Make sense?

I don't street race, so why keep a mod that I only use on the weekends?

It has nothing to do with racing, it has to do with keeping your car cool. Colder = less knock & the less knock you have the better. You don't have to be racing to have KR.. When people switch down to a 3.4, at the very least you should be using a COOLER range spark plugs, a COLD air intake, and a 180* t-stat which makes your car run COOLER.

I understand what you are saying about keeping your car cool. But why? A cooler car does not run better. In fact it is the complete opposite. A hotter car will run better, faster, more HP, more efficiency, etc under the same conditions.

The only thing a cooler engine will do is reduce knock IF you have knock. If you don't have knock, no reason to run a cooler t-stat. Consider Nascar. They are running engine temps around, or over 250°F. The key is setting your engine up with the appropriate mods to not have knock. Then you don't need to run a cooler t-stat to try and cheat the engine.

Again, if you can't run your car with a 3.4 pulley and a stock t-stat without getting knock, and need to revert to a cooler t-stat just so you can drive, you need more supporting mods.....not a cooler t-stat.
