Many of our customers have been building incredibly high output street and track cars and pushing them to their limits in extreme climates. If you, or your customers, plan on racing these massive horsepower cars in the heat of the desert, or anywhere else, it would be a good idea to check out AFCOs line of all aluminum tig welded heat exchangers. They offer lightweight bolt on kits with up to 350% more cooling area than a stock radiator.
