I run water with NOS cooling prduct that you add the NOS brought my temperature down dramatically i really like the stuff can get it at local car parts store.

I have heard a bunch of things for cooling. Redneck racing has a good idea, I have also heard distilled water with a good cap. If your radiator is aluminum, you can use a 22lb cap and anti freeze, but some will tell you that antifreeze will mess up the motor if it gets into it, I agree, if you leave the motor sitting there for weeks. Usually if the antifreeze got into the motor, more serious damage has occured. Make sure your pulleys are the same size or as close as you can get. If you are using a stock radiator, get the highest recommended cap and use a fluid that makes you comfortable. I took a thermostate and cut out the plunger and spring and left all the skeleton there. Our car runs about 210 to 220 all the time unless the radiator gets full of mud. If you have a way to keep that from happening,(besides... LEADING) let us all know. by the way I use a stock radiator (3 core) with a lower pulley that is a little larger than the top, and antifreeze at 50\50.

AS FAR AS KEEPING THE MUD OFF THE RADIATOR
I USE A TRICK MY DAD USED WHEN HE RACED,
I TOOK A HEAVIER SCEEN AND MOUNTED IN FRONT
WITH SMALL CHAINS ATTACHED AT THE TOP BUT
NOT THE BOTTOM SO THEY SWAY BACK AND FORTH
NOCKING THE MUD OFF THE SCREEN. WORKS PRETTY
GOOD, SOMETIMES IT PAYS TO LISTEN TO THE OLD TIMMERS.

Chris Paulsen at C&R Racing Radiators told me the following: 50/50 water antifreeze will boil at a higher temprature, but distilled water will cool better. DISTILLED water has better heat transfer properties. On the dyno setup he uses to evaluate cooling systems he has ZERO gain in any additive he has ever used and he has tested many of them. This dyno testing has been done with distilled water.

On my I-stock I dropped about 20 degrees going from a generic aluminum "racing" water pump to a Howard Stewart unit. The Howard Stewart pump has a seal that does not require a lubricant thus pure distilled water can be used. Keep the hoses new and use a 26 lb. cap. Hope this helps, SLEEPY.

To keep mud out of your radiator, try a fire place screen, attatch it at the top and let it hang in front of the radiator. Works for me!

1 more reason for not using antifreeze is if you blow a hose or something it will get in the ground and that is not good for the ground water some tracks i have heard that do not allow to use it for that reasn

we run 25 to 30% reduction pulleys on a bomber and a mod, with nothing to slow the water down in the theromastat and i have never had a problem with heat.

I run 75/25, 25 being anti-freeze and a bottle of water wetter. My engine guy told me to just run the water and water-wetter. I use distilled water also.
