Thermostat Delete I have an electric waterpump with a SBC 160* tstat in a stock LS1 tstat housing. Since I removed the HVAC system, is there any reason to keep the tstat? The car is a street/drag car that only gets driven during nice days. It is always allowed to warm up before driving, so I see no reason to have that restriction in the cooling system.

The t-stat is nothing more than a middle man that swaps hot coolant for cooler coolant. And it does it by opening and closing gradually as it senses the different temps of the coolant flowing across it. The t-stat must be able to close the door and stop the coolant flow once it senses that almost all of the HOT coolant from the engine block and heads has transferred into the radiator so it can start cooling off via Fans and Ram Air. Then the t-stat sits closed and waits until it senses the cooler coolant that just moved from the radiator into the engine block and heads to start getting HOT. Once that temp start to get very close to that 160* mark it begins to open which allows that swap of hot coolant in the engine/heads to change places with the coolant in the radiator that has been cooling from the last time that swap occurred. And so on and so on......
No t-stat and the coolant will just keep heating and heating and heating.....
On the highway, maybe you can find a sweet spot speed where it won't overheat....but once it reaches that point-of-no-return (temp-wise) its all downhill from there and it will overheat fast. City driving....no way to keep it cool for a long time.
A proper cooling system HAS a t-stat.
