Running without a thermostat ok?

I wasn't sayin you were stupid friend. We all take stupid pills from time to time. I was simply trying to point out that we were really not discussing electric water pumps in this discussion.....at least I was not. Those are not street friendly for the most part. Yeah, I know. You run one or know somebody, blah blah blah. There will always be the exception. I meant no offense.

First off I run with a T-stat, a stock mechanical pump in a cast iron housing. The stat I run is a 160 high flow. Car runs anywhere from 180-205 depending on the circumstances. 100 degrees out idling, I don't have a problem.

My reason for mentioning the CSR electric pump (with is rated and recommended for street use) is that they are not recommended to be run with a T-stat. I will say I ran mine with a 180 stat until I found this out when talking to a rep. Then I went with the largest of the restriction rings they sell.

If you read further down there is another member running a electric pump on the street. He runs 190 degrees with no restriction ring.

I know the OP doesn't have an electric pump. The reality of it is you should run a T-stat for reasons OTHER THAN overheating or cooling. Quickened warmup times and a temp healthy for the engine to operate in is what I mean by this.

On the flipside guy saying they run a 195 stat and never see over 180 on their gauge opens up a whole other can of worms.
