Maybe you need a multi pass radiator. Do you know what is in the car now; s=
ingle, double; triple pass?

questions.=C2=A0
What pressure are you running?
Do you have a pressurized expansion tank plumed into the system that takes =
water from the back of one of the heads then recirculates to the pump?
What kind of air flow are you getting through the radiator?

Hi guys,

My TR8 is running way too hot about 212F at full speed and at idle the temp=
