Dear guys. I've got everything I need to win a race. But the only thing stopping me is the temp won't stay low for more than 4 laps(sepang F1 circuit). Wheather temp here is adv 34 degrees so standard cooling is not enough. I've got an oil cooler as well. I've also got no more space to make a thicker radiator else it'll protrude out of the front grill.

Any advice greatly appreciated. Thanks!

You could probably try modifying your radiator. From memory, the standard 33 radiator has an inlet on one side and an outlet on the other side, it's not as efficient as it can be. I've seen people modify their radiators by putting dividers in the end tanks to force the fluid along a more efficient path to use more of the cooling surface. Check the obvious things too like thermostat, blocked radiator, damaged radiator fins etc.
Good luck,
Jason.

In cabin heater on full Smile
Maybe 1-2 bonet vents would help engine air more quickly, you should route hot air from radiator to top of bonet, while providing new cold air around radiator and into engine front.

Or making T pieces and pipings to custom sized radiators (where usualy are clima evapouratos) Behind bumper (in front of wheels).

Some also make openings in wheelarch part just above side indicators. Usualy to allow hot brakes air to dispose more quickly but maybe you could route also hot engine air through there.
