Corrosion Inhibitors

[moose]

Last year we noticed a decent amount of rust in our cooling system after we drained it, and have been looking around on the net for some sort of additive to prevent this. Is there anything (besides water wetter which we're still debating the legality of amongst the team) that your team adds to combat this problem (and doesn't come in giant drums)?

try for sodium benzoate or sodium nitrate they are readily available in small quantities.

use distilled water

I thought about distilled water, I guess all the stuff that makes philly water taste like trash probably makes our aluminum rust faster.

Water Wetter is legal, and the max legal concentration of it happens to be.....uhhhh......the exact concentration suggested on the bottle of Water Wetter.

my understanding was that water wetter was illegal. anybody wanna chime in on this??

I stand corrected.

[moose]

yeah I figured it was ok, I know it isn't a gylcol based antifreeze, but wanted to make sure it didn't somehow fall under the water pump lubricant title. However, the bottles I ordered came today.. so it'll probably go into the system this weekend.

[Gasperini]

I looked into this just now, and I think WW is Illegal because it is a pump lubricant. (It says so on the bottle.) The rules state that "water pump lubricants are strictly prohibited," so it is against the rules.

EDIT: WW is legal according to the rules committee. see my next post.

How do they actually know whats in your coolant, they cant test it. Not trying to cheat, but as far as I know water wetter is allowed.

Castrol radiator corrosion inhibitor is legal in all race classes in OZ. It comes in a tiny beer can, it's not on the castrol USA website so may be unobtanium

If there's testing equipment to detect minute particles for fuel with teams trying to get an unfair octane advantage, I'm sure they'd be able to run a pretty easy test on the coolant.

in this post it says WW is legal..

If WW is legal, I wouldn't use the recommended doseage from WW, but would strictly keep to the 0.015 liters per liter of water... just a thought.

[Gasperini]

I just got my reply back from the rules committee. WW is legal, as long as you follow the FSAE dosage rule.

Dear Kevin,

From the information we currently have, the use of Redline Water Wetter does not contravene the Formula SAE Rules IF the concentration is no more than 1.5%. Note: This concentration is approximately 50% of the concentration recommended by Redline of 1 oz per US quart.

Please be aware that as we concerned about not damaging Ford's pristine VDF surface, with the help of one of our OEM Materials Laboratories, we are investigating a method of quickly checking the concentration of cooling additives.

Rules Committee,
FSAE

What you guys really should consider is RC-20. It is a surface tension reducer like WW, but does not leave a chalky white residue. It is the darling of the racing Kart and ATV guys as well as those of us in really hot climates like AZ.
