Davis Roadster Heat Issues

63corvette · 03-07-2011, 01:58 PM

I have one I have raced since 2007 in all venues and I have not had a heating problem.
I run C-15 VP for fuel. I do run the isolator plate on the carb with a K&N scoop insert air cleaner so there is not any air coming in from the top which could restrict air flow across the radiator.
I usually stage at 160 degrees plus and even on hot days it only gets to about 210 after the round and usually cools down some on the way back to the pits. With a good fan and water pump it cools back to 150 or less after stopping the motor by the time I get the weather station numbers written down which is less than a 5 minute process. I usually shut off the fan and water pump at 140 to 160 in the pits.
I do run a alternator and dual batteries to keep the charge up on everything but I have not had a heating issue when it comes to going rounds.
The tranny is usually more of my concern and I do run a cooler there also. If it gets to hot and I do run a temp gauge on it I usually raise the body and put a fan blowing at the back of the engine for a few minutes. I also run synthetic tranny fluid.
Just My Experience.
