No Thermostat?

Many racers don't even run a thermostat.. Why is this, and it seems to me that your engine would run a lot cooler with constant coolant flow rather than opening up at certain temps? What is the reason for not running one and can I do it with my Pro Street Chevelle? thanks

What ever works best for your engine, i have had some that did fine with a 180 thermostat and the other liked a 160 and some liked none.

Some vehicles can actually run hotter without a T-stat. The T-stat acts as a restriction actually slowing the flow down which allows more time through the radiator for heat transfer. You will have to try your application to see if this is the case.

That is right. You should run a thermostat or at least the correct size restrictor. With nothing at all, the coolant can actually move to fast through your cooling system for the radiator to properly remove the heat. That is how cooling works in general. Cooling is the removal of heat. There is an optimum rate at which the coolant passing through the radiator can be cooled. Using different restrictor plates can tune for that.
I would run a thermostat instead because it does that and it allows for proper warm ups. Thermostats also have better maintenance of enigne temperature in changing conditions, (load on the engine, weather, gas quality, how well the car is running, etc.).

t stats

a thermostat is an important item in the cooling system
without one your warm up time suffers. maximum engine wear occurs during start up and the warm up phase as said earlier
it restricts the flow rate without one many old streeters over heat because the high flow of water stirs up the sediment and scale in the block and this gunk blocks those fine cooling tubes want it to run cooler try an oil cooler oil takes a lot of heat abuse in an engine. cooler oil equals longer engine life and oil life
how about water injection it will let you run more advance in your timming a bigger radiator more cores or a larger opening in the support pannel will help the trouble is it all costs bucks
how ever throwing that thermostat away may cost you more you can give it a try but me id give it some thought

I would say go for a 185* tstat. That is a good temp, usually.

The Dummiest thing you can do is Run your mouth with out Thinking BUD!!!! I have a blower on a sbc and it comes up to running temp in 5 minutes and runs 180 deg down the highway with a out a Thermostat! Using a restricker. YOU must talking about a HONDA? MORRION! Check post # 162779


Choice of thermostat's depends on application and what works best with your set up not what your neighbor is using in his.
