I don't run a thermostat in my Honda K series powered car. But I do run a large washer that has a hole in it the same size an an open thermostat to give the necessary back pressure.

You could use something like this and gut the thermostat

I'm looking at removing the Thermostat housing and replacing it with a straight pipe, making the rad cap the high point in the system, any thoughts on eliminating the Thermostat, I live in south florida, so no real cold temps to deal with.


The stat is important for a quick warm up. When the engine is cold, the mixture is rich which is harder on the cylinder walls (more rapid wear).

The primary restriction is the head gasket holes and bypass to prevent hot spots from running hard on a cold/tight/closed stat engine.

If you have excess cooling capacity (under some conditions), the stat maintains the temp so the design clearances are maintained.
