Recommended coolant type

Jax said

Thanks guys for all the feedback. Indeed here because of the high temperatures antifreezee is not an option. I will look into what type of coolant can be an option or even distilled water with some sort of lubricant. My car just get driven to the track ocassionaly, and that is like a 15 min drive. And raced on the track. So long street drives is not a concern.
It is a street and strip vehicle, however is pretty much used only on the track and barely on the street.

I think you'll find the only debate on the water will be whether it should be distilled or dionized. Most well water has small inorganics that can precipitate out. We call it 'hard water' if it has a lot. Public water also has things like chlorine. Not alot but enough. I'm pretty sure you'll have little trouble finding an additive locally or at least easily brought in.

Ask if the the corrosionb inhibitors are inorganic or organic acid technology. If its the latter, then I think its best to make the catch can into a recovery can so no air gets into the radiator.
