Road Racing - coolant.. what are you guys using?

what coolant are you guys using in your system? Standard Dex-cool? the green stuff? Straight water? Water with Water Wetter?

i want to be sure i can use the best stuff possible.. come summer time the temps are the local track are 90-100 for air.. and 140* tarmac temps

Dex-cool for 7 years and 3 changes..no problems at all.

Distilled water/water wetter.

Dex-cool on the street and Distilled water/purple ice on the track.

1 bottle of Redline Water Wetter, distilled water, 1 bottle of RMI-25. Make sure all the bubbles are bled out of the cooling system. Then repeat 2-3 times.

Evans Npg R , saw 316 oil temps this fall at vir with 212 coolant temps.

distilled water and 2bottles of water wetter. car doesnt see below 35deg temps.

GO-5. I dont like dex-cool work with it everyday but that a whole other discussion..

What is GO-5?

YEAH!! WAZZZATTT ???

Newest spec Daimler Chrysler (among many others) antifreeze/coolant. It's on the shelf at Peppies and elsewhere, albeit slightly more $$$ than Dex Cool.

Dex-cool user here.. though just starting to really race it, so we'll see. This car does indeed see a lot of COLD temps

So for those of us who don't have to worry about freezing temps, does running distilled water w/ water wetter pose any water pump lubrication or block corrosion concerns?

What's the installation procedure for above? Add the two bottles of WW, then top off with distilled water as necessary? Do I need to perform a coolant flush first?

Jim,

NASA banned the use of glycol based coolants. I've used distilled water only in my LT1 without any issues. since 2004.

Now, I have evacuated the cooling system a time or two ... ;)

75% Distilled water
25% Dexcool
Water Wetter

Normal temps on the track are ~210 water/ ~215-220 oil. Highest I saw before I changed to a Taurus e-fan was about 235 water/ 240 oil.
