I have a 08 Z06 with an ECS SC kit running around 7psi. Rest of car is stock, but when I beat on her the coolant temps will rise to 240ish. If I drive normal the temps drops right down. Any suggestions for additional cooling? I'd rather the temps stay in the low 200s regardless how bad I'm getting on the car. Car doesn't get tracked, occasional roll racing on the highway.

Look into a dewitts aluminum radiator and their brushless fan kit. You'll need to call and order the fan shroud that fits a centri blower

Brushless fan seems to be working awesome for a few people in really hot climates.

Send steve at RSD a pm, he has an awesome upgrade radiator for the Z06 I have a few friends that are using it and they love it.. One just took out the Dewitts and put the RSD in and made a big difference , Hes a forum member here ...

dewitts and brushless as suggested. seems to be the best combo

If you are getting hot while moving, start with radiator. Fan helps if you are getting hot at idle/slow speeds. Sounds like radiator is first step.

Dewitts all the way. Their quality/service is top notch.

i know sounds dumb but make sure AC condensor and radiator are clean and not full of stuff, my car did a lot better after cleaning AC condensor

Dewitts all the way am running Ron david but I'll switch as soon as possible.

Agree. Tough to do with the radiator installed.. it's almost like sand that fills up the space between the fins.
