Does anyone know of a larger water radiator that is available that can merely be "bolted in"? Or do we need to have one custom fabed. At both Willow Springs and Miller Motorsports Park, anytime the ambient temperature got above 80deg the car would only run 4 laps or less before the temp needle was in the red and the computer would put it in stupid driver limp home mode. :ack This was with the heater running full throttle. We badly need additional water cooling. If we can add additional oil cooling somehow, this would get the oil heat out of the water. (See my other post). This would probably help some, but I think the real fix is more water cooling. Help!! Thanks alot for any info.
