What are you racers putting in your radiators? Tap water-distilled water-waterwetter-prestone. what works best to keep it cool?

 

I use distilled water with one bottle of Water Wetter and about a pint of Sierra antifreeze. Most racing groups don't allow a normal antifreeze mix since the glycol is very slippery if it gets on the track. (Not true for HPDE's usually, just the wheel to wheel guys.) Sierra is not glycol based, so it's not slippery, plus it looks like Water Wetter when mixed in. It's the anti-corrosion additives in the anti-freeze that are of benefit with all that aluminum in the engine.

I just run distilled water and waterwetter in my race car. I run about 40% antifreeze (+water wetter) in the street car even tho it never freezes here.

 

Ry, don't you run with a radiator restriction by blocking off air on one side? Doesn't that conflict with running 100% water & w/w?

 

I do that in the winter because the race car doesn't have a thermostat. I can't keep the car above 3 bars if its cold out.

 

How much water and how much wetter?

 

99% water and whatever WW they say for our water amount. I forget how many qts we use. I always check the helms. I put the ww in first then fill w/ water.

 

don't you just open the little nipple thingy on the block and that one plug near the firewall and fill it up until water starts squirting out one of those two places? that prevents any air bubbles.

i never measured how much i put in.......

 

Any input from anyone????

Does a mix of coolant/distill and water wetter provide better cooling than water and wetter only???

 

Water and water wetter cools better than any percentage of water and coolant and whatever else. The problem with using water wetter only is (potentially) one of corrosion protection but most race car motors will blow up long before that's a problem
