In Reply to: HOW MUCH ANTIFREEZ TO MIX FOR COOLANT SYS? posted by adam p on January 24, 2002 at 15:43:47:
a trick w/ racers is straight water w/ water wetter from Redline. This is race only or track days only. Water will release heat much better withou the presence of coolant. Distilled water of course.
If you live in colder climates and drive on the street then the 50/50 rule will be best.
