The radiator mounts are moved forward to where the A/C condenser
was located to allow room for the new much thicker radiator, and Mark VIII fan,
which still has to be mounted slightly off set to clear the water pump pulley.
Since the fan is designed to lower the water temp that radiator can not on it's own, this was installed in the lower radiator hose to better sence the water temp leaving the radiator to turn on the fan if the temp rises above 185f.
I will have the fan wired up through a switch in the car to select normal, which will bring on the fan when ever the sensor calls for it. The other position will be Race. This will run the fan full time, except when the car is at WOT. During the short 11-12 second runs, the fan will not run. I will install a WOT switch on the carb, like is used in some nitrous systems. It will be connected to the normally closed contacts.This will reduce the electrical load, so the alternator is not running full charge trying to restore what the fan uses, thus saving some more HP. As soon as the car goes across the finish line, the fan will come on, and run till in cooled in the pits.
If this does not keep it cool, nothing will......
