Running a turbo system, you are adding in more heat than what the car was designed for. I am running two (2) turbos and track the car in Arizona. I still run the OEM cooling system but had to make some changes as the cooling system couldn't keep when ambient temperatures were over 110F. Here are four (4) things you can do.

1) Get a hood with a duct in it. They are made by several manufacturers. It will make a huge difference by itself.
2) Seal all openings on the high pressure (front side) of the radiator. All air entering your radiator shroud will be forced to enter the radiator, maximizing that air.
3) Get a MASIV radiator, if you can find one. They work extremely well but be sure to add, or make, some screening to protect it from road debris. It's core is brass and copper (that is why it works so well) but is prone to leaks. But they can be repaired by any radiator shop.
4) I added twin SPAL fans which were able to increase airflow thru the radiator by 3 times. They still use the OEM circuit for activation. Problem solved.

Good luck.
