Water additive

[Mike Summers]

Was not sure if it was this forum or not. Running the water through the frame tubes on my Lotus. Is there any additive to deter rust that is legal to race with?? Water and exposed steel are not a good combo but just checking to see if there was something new out there

Hello Mike,

Redline Water Wetter has corrosion inhibitor additives and water pump lubricant in addition to the wetting agent to reduce temps.

No connection, the usual disclaimers apply.

PS, it was great to see you at Mike Ostrov's!

Hi Mike,

Im in the same situation with my Cooper Formula 3 Car. Im still doing a little bit of research but the Evans Waterless Coolant seems to be something interesting. They make a track safe version.

I was under the impression that Evans NPG was flammable. I've seen a few websites that discuss it. So I would google it before switching to it.

I was seriously concediering. I think Ill shoot them an email and get the offical word.

Stand by.

I just got off the phone with Evans.

The only way it can combust is under a high pressure mist while being sprayed on to an extremely hot surface or flame. According to the gal that answered the phone.

She offered to connect me with a tech, but I told her that I was satisfied with the answer.

So like a pin hole leak in a coolant hose spraying on the headers?

That's the first thing I thought of, but there is virtually zero pressure in the system, even when above normal operating temp.

I Apologize for the sideways high jack... can you explain zero coolant pressure ? I know of a waterless coolant that uses a no-pressure vented cap. Similar set-up ?

[Snakedriver]

As I understand it the solution simply doesnt expand...rather the vaporization is almost nil. So the only real expansion is what ever air is trapped in the system.

[racerdad2]

That's cool ! pun intended

Which will bring the system pressure up to the usual 14-18 psi (depending on the cap you run).

PS - No such thing as no thermal expansion - very low, maybe, but not zero.

[Snakedriver]

I should have said that the pressure is insignificant.

I would also think that system pressure would be largely determined by how much air was in the system. If the system was purging correctly it would work most of the air our.

[romoman]

Doesn't the water pump contribute some pressure to the system?

[racerdad2]

Evans doesn't cavitate in the pump impeller like water does. Also, lasts for years, perhaps decades. Prevents corrosion. The key is to purge all water & air from system. Jay Leno swears by it Jay made a video about it. I believe it's on YouTube. IIRC the boiling point is around 365 F. I'd post a link if I knew how to on my phone...

[Snakedriver]

At some point I do plan on replacing all my anti-freeze with Evans. One car at a time and esp. the F-250.

I really wanted to start with the Cooper since it is totally dry and clean. Im still waiting on a return email from Lime Rock to see if they allow ethelyne glycol.

The Evans coolant is interesting stuff. It's about 70% ethylene glycol and 30% propylene glycol with corrosion inhibitor additives. Of course, the awesomeness costs $39 a gallon, plus the cost of the flushing agent. It does work but has only 2/3rds of the specific heat of water, so expect temperature to be higher. If you are low on cooling capacity with water, do your homework. I would hate to have a leak at T10 at Sears Point.

When I was on RX7 forums, Evans was a hot (pun intended) topic. It is not corrosive, is used w/o pressure cap, etc., but its heat capacity is lower, so if your cooling system is marginal, it may not work well.

[Snakedriver]

Thanks Dave,

That's the pickle Im in. The car is completely dry. The block has been boiled clean. So now would be an excellent time, but I have never driven the car.

So maybe to the Evans, and take the containers to the track if it doesn't work out and save it for the other cars.

...a bit late but the great part of Evans, it shrinks when freezing....just if you travel through a place like Flagstaff AZ when it is 26 heading to a race in March

[SEComposites]

Is there any reason why you don't want to run aluminum tubes down the side of the car?

[Rick Kirchner]

chromium-6? just kidding.....
