how much water wetter if planning on non antifreeze?
how much water wetter should be used if going to a non antifreeze coolant mix?
just installed my dewitts on my z06 and thinking of going to water wetter and distilled only.
thanks

I always followed the directions on the bottle and used just one bottle.

Use one bottle for most passenger cars and light trucks, treats 3 to 5 gallons or 13.2 to 15.9 liters. Vehicles with larger cooling systems should use two bottles. Small cooling systems should use 1oz (3 to 4 capfuls) per quart

This will prevent corrosion and not be a track hazard if put down on the track? What happens to cooling temperatures versus stock when running this mixture? Thanks for the help.

Water has a coefficient of dynamic friction (mu) of about 0.5. Water with 3% WW is about the same. 50/50 glycol to water is about 0.35, and straight eth-glycol is 0.2. In other words, if you ran 3% glycol you'd have about the same coefficient of friction as water alone, but get no benefit as far as lubrication and rust inhibition.
It is NASA legal as per the CCR, section 15.17.10:
Ethylene Glycol-based antifreeze and other additives that may cause a slippery condition if spilled on track are prohibited. Other water additives such as Redline WW may be used.

I have a question relating to this. My car is still a daily driver and I also DE it about 5 weekends a year.
If I switch to water and a bottle of water wetter only will I have issues driving it like this every day?
Also doesn't the anti-freeze not only lower the freezing point but also raise the boiling point of the water? Does anyone running straight water have problems with boiling?
I check my hoses during my pre-track check and also periodically during the events but if a hose does ever go I don't want to cause a slick.

Greywolfe, running straight water (with an anti-corrosive and pump lubricant, of course) is superior in almost every way. The reason to run antifreeze is just that - to keep your water from freezing. As long as you put glycol back in whenever there is a risk of freezing temps you'll be fine.
Water is much better at cooling as it's heat transfer capability is quicker. In other words, it will absorb heat from the motor faster and then release it in the radiator faster than a glycol mix. And of course the issues on track have been covered.

For an aluminum radiator, distilled is recommended. Just go to a grocery store and buy the big 2 gallon jugs cheap. Make sure you get distilled and not spring water.
I've seen Peak brand distilled water at the auto parts store for as much as a gallon of antifreeze! What a scam.

Straight tap water can have quite a bit of minerals in it. I don't get fancy with mine and just use filtered water from here at home. Distilled is good too!

How about you guys stop using water wetter and start using better stuff like DEI's radiator relief.
I have this in my z06 and it brought my temps down 30 degrees! I have some if you guys want to try it, PM me for details!

I use 2 and no a/f
I have the dewitts and the twin fans
In Middle East at 35deg C, I get 100deg C water and 118deg C oil
Brilliant
Best move i ever made.
In traffic it runs mid 80s/low 90s

I'm happy to try it if it meets my requirements. But my car runs cool enough as it sits, so I'd need a compelling reason...as stated in my first three questions.

Where is the best place to buy this? And does it really work?
