side effects of water instead of coolant?
 
Just wondering if by having water in a rotory engine if that could cause the car to overheat because the water would boil? I was running water and my FC got really hot, I'll see if coolant fixes that, but i was wondering if that is a probable cause.

if you're using just water, add redline water wetter to it.

"redline water wetter "

hey funk lord where du buy it at? i went to auto zone and asked them but they didn't know what i was talking about

I get water wetter from:

www.mojoracing.com

They are racers and good people. I run water and water wetter only in my IT car with no problems.

WARNING - your engine is an aluminum and iron sandwich. Running without the corrosion inhibitors in antifreeze will seriously shorten it’s life.

This is also why you should flush & replace the coolant each year..

Water Wetter has corrosion inhibitors and lubricant in it. It will not prevent freezing though!

I did not know that.

So - the pitch is - don't use plain water alone..

run with abit of coolant atleast or your water pump will go Kaput in time.

Water boils at what temp? Freezes when?
50:50 boils at.............See what I am getting at.

Most antifreeze is 90% EG or PG, 3-5% water(used as a mixing solution), and 3-5% lubrication/anticorrosion additive. Since Redline water wetter is labelled as a pumplube and contains anticorrosion additives, a lame conclusion is that it will perform those two duties as well as antifreeze if used as directed.

But, why the hell would you want to run straight water? Are you running straight tap water?
You have icy winters, don't you?

This needs to be touched on.

You should use distiled water that you get from the store. You should not stick your garden hose in the radiator and fill her up.

Distiled water lacks the minerals the tap water has.

I have to ask?
Why use water...period?

DaveB 08-16-02 09:57 AM

From the Water Wetter bottle:

Dyno test results-

50% glycol/50% water - 228 F
50/50 + Water Wetter - 220F
water only - 220 F
water + Water Wetter - 202 F

I store my car in the trailer in the winter, so I use 50/50 then. When the car goes on the track, it goes to distilled water and Water Wetter. I am sure that there is 5 to 10% antifreeze left. The reason for water only is the evaporation in the event of spillage on the track. If you have ever encountered antifreeze at speed, you know that it is just as bad as oil and doesn't evaporate quickly. I don't want to have my competitors take me out because of my spilled coolant or take myself out on my own spilled coolant.

Street only?..........I would do antifreeze and drive so that the car doesn't overheat. My street Rex has never had an overheat problem.

Etheline(sp?) glycol does not dissipate heat or absorb it as well as H2O. The Glycol is a type of alcohol, which, inherrently, has a lower freezing point than H2O. So, with antifreze in our coolant ou prevent the coolant from freezing. The alcohol also has better thermal properties than H2O.


Just some chemestry for you all.
