At anything above 1.0BAR, my coolant is getting blown out of the radiator/expansion bottle etc etc, due to the heat created in the CT9.
So, I'm going to put an oil cooler, in the return to the motor, to drop the coolant temp back down as it leaves the turbo.
Simon Norris did it on the Evo, and it worked wonders, and stabilises the coolant temps no end.
