Additive in water for Alumi heads?

stroked 340,there is no anti freeze or water in evans coolant.
NHRA track here in Woodburn,OR says ok to run,NHRA track Las Vegas,NV says ok to run.

On the cars that have aluminum heads we drop the water at the end of the race day and on the 10 sec street car we put 1 quart of anti-freeze back into the cooling system and fill it up with water and drive it home.

Cooling system on 10 sec street car.


And since Evans doesn't boil at 212 more like 400 degrees you don't have to run a high pressure radiator cap.And it doesn't freeze till well over 100 below freezing.

Been using this in are semi's and have not had any problems.They run threw wyoming every week.

Costly at 42.50 a gallon.
