Coolant suggestion

[drpepper]

I just noticed in the rules that glycol based coolants are not acceptable, so I was wondering what other people are using. The only water additive I can find (other than Watter Wetter) is Valvoline Zerex Racing Super Cool. Does anyone have any other suggestions? As a bonus, is there anything that has anti-freezing capabilities?

Royal Purple has 'Purple Ice', same as Water Wetter. I've read somewhere that dish soap works as well, and I've noticed that the Royal Purple stuff does seem to be a LOT like soap...

As for anti-freeze capabilities, I'd just fill the system with antifreeze for the winter. Which reminds me, I need to drain the water out of my car, like tomorrow... !

Use dish soap sparingly :D

What it does is break the surface tension of water allowing it to stick to the insides of your engine and radiator better. Water wetter does that without the suds.

When the water makes better contact with the inside of your engine, it does a better job of removing heat.

The reason for the ban on ethylene glycol is that if you burst a rad or hose, it makes the track slippery. I should imagine that using soap would do the same thing, but maybe to a lesser extent. I used water wetter last season with good results.

Thanks for the help! By any chance has anyone tried Neo? (http://www.neosyntheticoil.com/products_co.html)

Use fabric softner (not dish soap) the water soluble oil is what does the trick.(liquid...don't use the sheets)

we've always just used water and some water wetter.

Has anyone here tried that Evan's coolant?

While ethylene glycol DOES make the track a little slippier than ordinary water does, it's not exactly because it's inherently any slippier a material than ordinary H20.

Water has a vapour pressure of 17.541 mmHg at 20 C.

Ethylene Glycol has a vapour pressure of 0.06 mmHg at 20 C.

Water tends to evaporate at roughly 284 times the speed of pure ethylene glycol on an average summer day at the race track.

So, while I dump a shitload of water when I blow a rad hose at the top of turn 2, it's slick for a lap or two.

When I dump a shitload of coolant at the top of turn 2 after blowing rad hose, it's going to be around a little longer than just 2 laps.

Note, these numbers are for pure ethylene glycol, and not the standard 60% / 40% mix that most people run as coolant. Because ethylene glycol doesn't behave as one might expect, it's hard to predict just how quickly a mixture of water and coolant would evaporate. IE, the freezing point of straight ethylene glycol is about -12 degrees C, while a mix of 60% EG and 40% water has a freezing point of about -50 C. A straight water mix freezes obviously, at 0 C.

I use a mix of H2O, Redline Water Wetter, and Honda Water Pump Lubricant. Works great in my VW racecar.
