Car with no anti-freeze.

[Brad Roberts]

You sent this to me via FB lol, I live in SoCal!! and my cars typically sit in trailers overnight.. when I know it's going to be colder than a witches tit in a brass bra

[trekkor]

I'll be sleeping in the trailer.

Sonoma race.

[trekkor]

...and I don't like witches.

Can't you just dump some denatured alcohol from HD in it?

[Brad Roberts]

How about this:

GO HOME!! You live 15min from the track!! put the car inside the trailer..

they make cheap magnetic block heaters, you know..

When I raced Karts a guy lost a rotaxmax motor due to spitting from Iced coolant.

Wind chill does not affect a machine. If you measure the temperature of the cold engine block or battery of a vehicle in your driveway, you’ll see they are the same as the ambient temperature, regardless of the wind.

Wind chill is a measure of how fast a warm surface is cooled. You can't cool a surface of an engine or radiator that is at ambient temperature to less than ambient no matter how much air you blow on it.

Wind chill between the freezing point (0 degrees Celsius) and minus 27, the risk of frostbite is low. But a wind chill factor between minus 28 and minus 39 C will cause exposed skin to begin freezing in as little as 10 minutes. And at minus 40, you’re in a high risk situation, with exposed skin beginning to freeze in only five minutes. Machines simply are not affected.

This question comes up all of the time with boats here in Missouri. The rule we use here, that seems to be accurate is 24 degrees for 24 hours before water in the block will freeze. Last year I left a glass of water on the dock in freezing weather overnight (around 29 degrees) and it didn't have any ice in the glass. 24 degrees for a few hours is not going to freeze water in your engine. But if you are paranoid, like the others have said, drain the block.

Seriously? I suppose it is possible, but the shape of the moving body would have to be pretty precise to get enough air moving fast enough to change pressure enough to lower the temperature in critical areas.

Glen - he's not talking about wind chill. He's talking about conservation of energy and the ideal gas law. Think of how cold a carburetor gets when a lot of air moves through it. PV=nRT

That works on the block. Not on the rad.

OK, so he needs a engine compartment shaped like a venturi?

That carb get cold mostly because of the evaporation of the fuel.

Yes, that's what I was saying. Not likely.
Wind chill will not lower a body to less than ambient temperature, so if Mr. Rogers was talking about wind chill, he's off base and you're right.

Fill the cooling system with the cheapest vodka you can find!

In the '20s it was common to use alcohol for anti-freeze. I was at an historic farm days event and some guy had me plowing with his 1920 Fordson, with alcohol for anti-freeze. The alcohol was boiling away and blowing right into my face. I didn't get intoxicated, but I got sick as hell.

I used the term "chill factor" to cover several types of cool down. As the previous post noted you can not get the temp below ambient but that is in error, especially if there is any moisture on the surface and you have air movement which you will, then what is called latent heat of vaporization comes into play which will act similar to what we use as a refrigeration system now days. With water that equates to about 970 BTU/LB of water. In the days before me (and I am old but not that old) ice was used and the heat absorbed by melting the ice kept food cold. I do remember my grandmother having an "ice box" until about 1952 or so!

So where does the moisture come from? Condensation mainly especially when the car is hot and then cools down at night! Sooooo, be safe and add some anti freeze if allowed.

My grandfather talked about the old days of draining the radiator every night and having to pump water into a bucket each morning to fill the radiator so he could go to work. Ethylene glycol solutions became available in 1926. I am sure it was expensive for someone making 2.5 cents an hour. He may have used water because it was free.

Three dogs under the car? Like the other guy said, "24 degrees in Napa?" What happened to heaven on earth?

You spend thousands of $$$$ on a race car and you are trying to find ways to avoid putting antifreeze in it! In addition as somebody mentioned that antifreeze lubricates the insides, please just do the right thing and break down and buy some antifreeze and stick it in there. It is worth it for peace of mind....

[porsche4life]

.....


It's in the rules that can't run antifreeze, as it slicks up the track when the hunks of junk spill it...


And it's a lemons car.... Saying Trekkor has 1k in it is a stretch!
