kinda like the oil question what is a good ratio for coolant to water with or without additive ? we run 60%water 40% with water wetter i think that is what its called

best ratio is 100% water

when we run straight water it seems to run to hot

you have more issues then whats in the radiator then do a search on cooling we cover this about every other day on here lots of good tips and maybeyou can see where youcould change something to get the temp down. just how hot does it get?

what's your radiator setup like? got an air box?

as far as coolant we run 50/50 we use distiled water and anti freeze and we are lucky to get 190 out of her. anti freeze lowers the boiling point of the water

ANTI-FREEZE is a chemical to stop water from freezing. Has nothing to do with heat. The best thing for cooling is water and some chemical to release the water tension. like water wetter or even fabric softner.
Most tracks dont allow anti-freeze that stuff is greasy and doesnt dry up very fast.
What stops water from boiling is pressure. Make sure you have a good racing radiator cap and you will not boil over so easily.

straight water transfers heat much faster than coolant. if you need some lube for your water pump just run some water wetter or purple ice...

jay116, you're wrong. anti-freeze also raises the boiling point. a 50/50 mix of anti-freeze and water increases the boiling point of water alone from 212 degrees to 223 degrees.....add pressure and it goes up even more.

thanks outlaw for a minute I thought that I spent 80,000 on an education in auto mechanics for nothing

if it raises the boiling point why isnt it called ANTI-BOIL.
My point was its main purpose is to stop the water from freezing and its side effect is the raising of the boiling point.
My statement still stands the best coolant is just plain water. If your motor is running hot does it really matter when the coolant boils. 240 degrees is 240 degrees.
If your running hot there is another issue going on inside that coolant system.

then why don't they just put water in the cars that are in florida???????

This is cut/pasted from Stewart Components website tech support section.

Tech Tip #4 - Coolant, Fans, and Hoses

Coolant
UNEQUIVOCALLY WATER IS THE BEST COOLANT! We recommend using a corrosion inhibitor comparable to Prestone Super Anti-Rust when using pure water. If freezing is a concern, use the minimum amount of antifreeze required for your climate. Stewart Components has extensively tested all of the popular "magic" cooling system additives, and found that none work better than water. In fact, some additives have been found to swell the water pumps seals and contribute to pump failures.

In static cooling situations, such as quenching metal during heat treating, softening agents (sometimes referred to as water wetting agents) will allow the water to cool the quenched part more evenly and quickly. The part will cool quicker, and the water will heat up faster. However, an automotive cooling system is not static. In fact, the velocities inside a cooling system are comparable to a fire hose forcing coolant against the walls of the engine's water jackets. If the softening agents actually aided in cooling the engine, the temperature of the coolant as it exited the engine would have to be higher because it would have absorbed more heat.

Anti-freeze lowers the freezing point, raises the boiling point, and prevents corrosion. It is also designed to transfer heat effectively. The difference in heat dissipation between straight water and an anti-freeze mix is negligible. There is no wrong answer as for which to use. This debate is moot.....plus it's been argued to death already.
