I took the t stat out and went for a drive. It runs about 200 most of the time and 210 with ac on. Don't know where to go from here other rhan taking off the supercharger and go test it.

One issue with the SBF set up is the impellor cavity of the water pump doset fill completey unless a bleeder valve is added or, you have a way to vacuum fill the engine coolant the way the factory does. With air in the impeller cavity pump efficency is lost also causes the coolant to boil at a lower temp due to cavitation.

Try a restrictor plate in place of the thermostat. Start with about a 5/8 hole.

Installed a restrictor plate with a 11/16' hole. I now run abou 185 low side and 198 on the high side. This is on the throttle up hill at about 4o mph and coasting down hill. On the high way about 190 at 60 mph.
This I can live with. It's 89 degree's out now so we will see.

How long did it take to heat-up after a cold start?

Just to be clear, you went from no thermostat/no restrictor to a restrictor with an 11/16 hole and it runs cooler with the restrictor in place.

Hey merc, remember when you said that slowing down coolant going through the radiator could not possibly increase cooling capacity? That this whole idea is a myth?

Yes, because when you are slowing down coolant in the radiator you are also slowing down the coolant in the block because it is a CLOSED system that is UNDER pressure.
Think about it ...

You are so fucking dense & simplistic, it borders on idiocy.

I have slowed to the coolant and seen a lower operating temp, wywindsor just did the same thing to his engine and saw the same result, juicedcoupe has seen the same thing at his work.

On a
closed system
how do you "slow the coolant" by adding or removing a restricting device?
Pressure goes up or pressure goes down.
Changing the
water pump and/or pulley
can slow or speed up your system, right?

It did take a hellva long time to come up to temp. I don't recall the exact time but a lot longer than normal.
