Re: Closed loop vs open loop problems
Walter, I know, but this is just a shitting backup plan or when it gets real hot. 50 degrees outside temp racing on a frozen lake equals big problems. I will be running this setup also during hot spring like weather. Cold water+hot turbo manifold=cracks :P

If you are having problems hitting operating temp, then attend to whatever mechanical problem is causing that.

The problem is that most people don't realize that proper operating temp is both the coolant and the oil temperatures.
I wait until the oil pressure is low. About 16-20 psi at idle.

I know brake rotors in a road race car can crack if they get hit with cold water. They also never crack on the track, just when they cool off. I haven't had anything good come from wet weather racing. I had to drive about an hour stuck at WOT, because of a throttle cable issue. Randy
