Excellent example of Trackable/Useable Horsepower!
I would have liked to view the operating temperatures of the engine & gearbox.
How HOT was the water/ engine/trans oil?!...Mark
The race cars generally just need an oil cooler added to them and either a 160 thermostat or none at all.
From experience you only need an oil cooler if you are going to consistently run over about 220 F.
The factory found a naturally vented area for the oil cooler in the Pantera. It is in the right rear wheel well with the cooler mounted inside of the "splash shield" and louvered.
The natural motion of the circulation of the tire causes a negative air pressure drop over the oil cooler radiator while the car is in motion.
The water temp then almost becomes irrelevant. As long as you don't boil over, you are ok.
That won't happen to about 252F with a 16 psi cap and a 50/50 mixture.
I doubt that the race car engines run particularly hot.
The ZF, I don't know BUT so far have not seen a separate oil cooler for one.
For that matter, Mustang race cars transmissions are not an issue for running hot, HOWEVER lots of them need a cooler and pump for the rear end.
