Out here most of the drivers i know dont run a thermostat, what do some of the rest of you think about that and do any of you run them?

If you don't have a temp problem, then that works. I always use a restrictor. You have to keep the fluid in the ratiator long enough to transfer the heat.

Kwtracer would the restrictor be like cutting the top of a thermostat off and just using it. Eddie

I have always ran a stat with two 3/16-1/4" holes. That way if you get caught in a rush to get on the track the motor always has some heat in it.

No thermostat. No restrictor either. But I'm running a top-of-the-line waterpump from Stewart (www.waterpumps.com). Follow ALL their recommendations with their pump and you'll have no cooling problems.

we have always just gutted the thermostat out and use that as our restrictor

We stay cool with a gutted thermostat. I've heard that a little bit of dish soap in the water works on the same principal as water wetter (breaks up surface tension). I don't know if it makes much of a difference, but it's so cheap and we have no problems that it's custom now.

Of course the other bases are covered like: racing aluminum radiator, good racing pump, and shrouds- front and back of radiator. Don't forget the important relationship between timing, jetting, compression, and fuel quality. This will definately affect operating temperatures.

I run the restrictors, 5/8 winter, 3/4 summer in AZ. I like the stewart wtr pumps also. Those checker/auto-zone lifetime swap pumps aren't worth the cheap price when you risk one going out on you and overheating youre engine.

Here is what I looked at to determine if I would run a restrictor. http://www.stewartcomponents.com/tech_info.htm

I just take the moving parts out of a thermostat and put the rest in the intake. The rest of the motor is stock stuff, pulleys, pump, radiator, shroud and the like.
