If no ethylene glycol, what are my options?


#1

The rule states:
"7.11.1. Use of an ethylene glycol (coolant) is prohibited. Substitute coolants (e.g. “Water Wetter”) are highly encouraged for all competitors. "

So what do I use? 100% water?

What does everyone else do?

Sorry if this is a n00b-style question.

here is one example of what you could use

(edited out recommendation for propylene glycol based antifreeze)

Bruce - are you sure about that? I thought all glycol based antifreeze was prohibited during competition.

We use distilled water + RedLine water wetter and have had no issues regarding cooling. Only issue is with winter weather, because this mixture will freeze.

I did some more googling and it appears that propylene glycol can also cause slippery surfaces, so I’ll withdraw the propylene glycol recommendation. (I edited the original message)
thanks,

So do you just flush and add 50/50 for winter storage?

I use distilled water during the year (with a touch of water wetter for good measure). I drain about 1/2 gallon in winter and add coolant. We’re usually allowed to run with coolant for the February races because of the freezing temps. This way, the car gets a fresh flush at least once a year.

FYI - Water Wetter does not lower freezing temps - it’s just supposed to help the cooling properties.

From what I have heard, pure water transfers heat better than a coolant/water mix. The coolant is there to prevent freezing in the winter and also raises the boiling point of the mix, in case a problem occurs in the cooling system…which we all know happens in neglected street cars.

In your Spec E30 race car, the cooling system should be working correctly, thus no need for a higher boiling point. I had some minor cooling issues after building my '89 and thus replaced the radiator with a new one from BimmerWorld. With just water, I have never had a cooling issue, even on the hottest days in the Southeast.

Trivia: did you know our late-model M20 cooling systems have (successfully) been used to cool S38 M5 drivetrains (dropped into E30s) for street & light track use?

I plan on using dihydrogen monoxide as my coolant. Do you guys know if that is illegal? It’s very cheap and some kart guys use a variant of it with no ill effects - as far as I can tell.

By the way, dihydrogen monoxide is used as a coolant in nuclear power plants, so you know it has some great cooling properties.

I know it’s a controversial topic. There’s even a website dedicated to it: http://www.dhmo.org/

the MSDS sheet says "protect from freezing" and "do not store in a rigid container", not to mention that it reacts with some metals (I don’t know if those metals are in our engines).

I was just joking, man. LOL!

Dihydrogen monoxide = H20 (water)

More significantly, it is adavntagous for lubricating the water pump and seals in the engine.
