Kelly,
We're looking at cooling the turbo, from the schematics it appears= as if they are feeding the turbo HOT water (high pressure is all after the= pump) and returning it to the pump inlet, in effect recirculating hot wate= r in a loop that is not seeing the radiator except in the mix?
How did you do your TO4?
