The new Supra has 3 radiators cooling things down as well. Matter of fact, Toyota built in excess cooling capacity, then partially blocked the large front/center air intake. Tool out the stock vent grille for instant added air flow through that nice big air intake. Use the right oil, change it every 5-6K miles, and your not likely to run out of cooling easily, even tuned for 100hp+ over stock, possible well beyond that for all I know. The car is even set up for a rear diff cooler.
