No I haven’t but being a top bulb racer as soon as I see a flicker I’m on the floorboard. Thank God we don’t race with a 5 bulb tree anymore. I have my cooler spaced and mounted in front of my radiator which has two sealed fans on it. I have my rpm limit set at 4200-4400 while on the brake on a 5780 stall converter. It cools off pretty fast. My buddy sells a pump system that will cool your fluid while the car is shut of but I actually have a system that I had on a carivan when I towed it behind my motorhome but never installed it.
