This car has always been on the raod more then the track but that is changing this year. So I will cut the stock t-stat and use it as a restrictor plate. In past cars I would pull the t-stat and run restrictor plates. I agree about the water can move to quickly and not pull as much heat out of the motor.

i will run with no t-stat to this season. i did it on a road course last year for one event with no issues.
does the t-stat route the water a specific path and with no t-stat, does the water go the wrong way? a tech at evans told me that but I just don't think so.

no, water will just flow with no restriction. Which is why mez. made the race pump @ 35 gpm, so the coolant will move a little slower, making the need for a t-stat not needed.
I'm gonna be installing my pump tomorrow, and there's no hint of a tstat going in anywhere.

You tune the flow with restricter plates, if you have a high flowing pump and it's running on the hot side you put in a smaller restricter plate, you can swap the plates in and out until you find the one that works best for you, most kits come with 3 plates.
Setup:
438" Iron LSx with ET LS7 heads
Double pass radiator
5x gpm Meziere pump wired to come on with engine running all the time
1600cfm fan turns on 185 off 175
engine stays a nice 180 degrees.

I have no t-stat, waterpump is on a switch so I can turn it on and leave it on if needed.
I only have the factory temp guage so the accuracy of that is questionable, but I know that before with the stock pump/tstat the car would get up to 200 and never go over, and now it says a touch under never really goes over. And that is on a day when it's a goos 85 to 90 outside and making 2 passes within a 1/2 hour. My fans come on at 170 and go off at 160 (so once the car is running, they just pretty much stay running) and I have no problems.
All I have in the radiator is water too, no water wetter, no coolant, just regular old tap water, no problems.
Next year I will probably put a big single fan on it and wire it with the waterpump just so I can turn the fan on and off with the waterpump.
