Default replacing coolant with H2O?

If I want to just go to a local test and tune, do I have to worry about replacing my coolant with water? Don't want to get myself into trouble and the track website doesn't speak to it. Not having been down a track before maybe its something that is understood and I just don't know.

Thanks for the feedback.

They usually don't require it unless its a large event then they might. They do at pinks all out.

Never knew that. I've never changed out my coolant for water. Not only would this go against the whole purpose for developing coolant in the first place (higher boiling point, I would assume), but given the aformentioned, would this have any effect on performance? Or would the temperature of water and coolant rise and cool at the same rate?

The point behind running it at the track vs antifreeze is in the event of a busted hose or some other failure, you aren't coating the track with anything other than water.

The science behind modern coolant I'd have to leave to someone else but to my knowledge its not to increase the boiling point. Aside from removing heat from your engine its other purpose is to avoid catastrophic failure of internal engine components when the outside temperature goes below 32*F. I'm sure modern coolant has a host of other benefits for your engine as well but like I said someone else would have to chime in on that.

Yeah, I knew about the logic behind it -- takes forever to clean a track after a catastrophic failure.

I was just curious if that would effect performance.

If they do it at Pinks, I'm going to assume there are some pretty knowledgeable tuners and mechanics present that obviously don't object -- maybe I'm over thinking it.

I mean, I would imagine you wouldn't want to use it all the time since, as you eluded to, there are mechanical reasons for coolant, like lubrication and non-rusting of the pump and such, but if there aren't any short term performance impediments then I guess it's no big deal.

Anyone else know whether water heats faster and cools slower than coolant?

Most racecars run straight water for coolant, with those that are the exceptions running something like Evans coolant. Coolant is EXTREMELY slick when spilled, I've seen EMT's get injured slipping on coolant (which was against the rules to have.....) after a bad wreck at the track while trying to assist someone who hit the wall.

Between racing and growing up on a farm using water in all of our leaky equipment radiators, I've never had a single issue using water. If you're racing, throw in some Water Wetter to break the surface tension and it'll outperform coolant. Just don't forget to drain before it freezes or you're in for a mess of trouble.

For what its worth, its almost universally not expected at a 'Street Legal' drag racing kind of event. Large national points events and the like often mandate no coolant. Usually, if you're to the point of not being able to run coolant on the drag strip....you're probably deep enough in that you'll be aware.

Hey thanks. Not the technical explanation we were looking for, but answers the root of my inquiry, which is pretty much hoping I won't be asked to drain my coolant every time I go to the track.

I've been at a few test an tunes and never had to.

Beware, if you go to Capitial Raceway in Crofton, Md. they'll make you drain your antifreeze if you run faster than 11.50

Thanks 4DRUSH. I live 10 minutes from 75/80 so that's where I plan to take the car for my first trip down the track.

At the moment I'm trying to figure out what to do about a helmet. Don't want to buy one for a just a couple trips so I'm looking for one of my buds to let me borrow one of the motorcycle helmets.

Who knows though I might end up getting hooked, although I couldn't afford to support a drag racing habit.

WHen I raced motorcycles it was the same thing. We were not allowed to run coolant because it would make the track slippery if spilled out. We ran straight water with water wetter in it. I never noticed any differences in temps though. I did however see people go down when they would a coolant induced slick spot from someone who didnt follow the rules and crashed.

I would change the ratio of my mix on my small block powered 240z from 50/50 water/antifreeze to 80/20 water antifreeze during the summer and the car would run cooler. Of course this is Phoenix, Az where it routinely goes over 110 in the summer.

I would be more concerned about doing this on a iron block engine over an aluminum engine. Antifreeze also prevents corrosion.
