If that's an open invitation I'd love to go to Florida and check on running temps, maybe have a few beers and catch a redfish after. Don't know if I want to bet any money as I've never raced and at 62 my reaction time may be down a bit, maybe not.
I could write a bunch of formulas and fill the letters with numbers- ohms, energy to accelerate the mass of my twin electric fan blades, voltage drop/foot of wire, rotaional resistance at different air densities, efficiency ratings of the fans and A/C generator, Lenz's law, Newtons second and third laws but that would take about a week so I'll just tell you when my car is idling in the driveway, on the rare occasion the engine is actually in the car, the rpm slows when the fans come on. It takes horse-power to drive the electric fans as well. I suppose if you're at the strip you could switch the fan/fans off just at the lights and turn them on agin at the end of the run.
I have an aluminium rad with twin spal fans and shroud on my car and have not had overheating issues. I don't live in a hot state. The fans, rad and shroud came with the car when I bought it, I would not take off good factory cooling components and exchange for what I have but I'm happy with it. I also have a smaller dia. water pump pulley so the pump is turning a bit faster. But as Ragu says these things can over-heat and burn out, one reason why I wired mine separately with a relay for each fan.
I agree-if your not running a heater then run a hose from the back of the head to the pump to keep the water flowing through the head.
