HI,

what is the best rad available on the market?

have a supercharged s running 400bhp and on track im seeing the water temps creep up and up.

I need to sort the issse before uprading my SC kit to 500bhp and causing further issues.

 

I recommend getting an aluminum radiator and set a set of spal extreme peformanse fans.

 

The question is which alloy radiator performs the best?

 

ron davis then koyo. j's racing. asm all others seem to be the same radiator good luck may want to look at an oil cooler as the factory oil coolers put a lot of heat into the coolant and the ron davis system has an oil cooler built in good luck

 

any links to the Ron davis rad?

 

Are you running an intercooler in the front?

 

ron davis builds to spec http://www.rondavisradiators.com/Welcome.htm but have heard its still cheaper than asm or j's racing and I second forcedbird on the intercooler how thick and how close to the bumper is it mounted I vented my hood and have had a carbon fiber vented hood and they both made a difference

 

If its tracked, what about a dual pass? That seems like the best bet for a hard run car.
