Coolant use in HPDE car

[NSXLuvr]

Those of you who track regularly. Which of the following combination do you guys use for cooling and Why? I track my car 6-8 HPDE's per year. The car is never driven in Temps below 40 degrees F. However, it frequently sees temps greater than 90 degrees F.

A. Honda Type II coolant.
B. Honda Type II Coolant and distilled water/ Red line
C. Honda Coolant and distilled water.

I need to flush my coolant and was debating between the choices.

TIA

Water (no anti-freeze) with water wetter would be optimal at the track. Here in Michigan, I run about 3 to 1 (water to anti-freeze) with water wetter in the summer and go to 50/50 in the winter. Anti-freeze or “coolant” is not nearly as efficient at transferring heat. Of course, going without anti-freeze raises the freezing point of your cooling system.

Thanks DanO(btw- luv your website)

any other thoughts- am getting the 60k service done and was debating between the choices.

I have run for several years with nothing but the factory antifreeze and my temp never moves a bit.

Well, I was supposed to, but a couple of birthdays got in the way (mine and my mom's). I was informed that I would be required to be in attendance.

If you don't have a problem, don't fix it would be my suggestion. I am running Honda Type II coolant with a bit of distilled water beacuse I ran short, and water wetter. My temps never climb when on the track so I am very happy with this set up. The Honda II Coolant is a 50% dilution in the jug.

I have been helping a friend sort out his S2000 turbo set up which has been having heat problem. We switched to Honda II at a 20% dilution with distilled water and water wetter, as compared to the set up I am running, and recorded a 12 degree F. drop at full boost/stablized temperature. I understand one can get even better results with less anti-freeze but we aren't comfortable with that. The anti-freeze prevents freezing and has anti-corrosion chemicals, as well as lube for the seals in the water pump. In Portland we rarely see temps below 30 degrees, and this car is stored in an attached garage so it never gets cold. I think the 20% dilution is still good to 15-20 degrees.

Very sound advice!
