Race Coolant

[elenitro]

I had an issue with overheating in a race last weekend and have been looking for something that would keep the engine cooler than just a 50/50 mix of glycol/water. Has anyone had any experience of this?

I used to use water wetter, worked well for me, I used it with out anti freeze. No corrrosion issues on my cast iron boat anchor block and head and helped to keep temps down. Also worth while making sure the rad is well ducted and air can flow to and through the rad easilly. You might find that you really need a more effienct rad core, Serck did mine 4 core and z pattern fin design no more cooling probs, infact I used to have to tape up some of the rad on cooler days.

No antifreeze, just plain old water and either 'Water Wetter' or 'Millers Extra Cool' for me! Glycol stuff is actually less efficient than water; its not called antifreeze for nothing

Another vote for WaterWetter.

As a previous poster said, adding glycol to water reduces its ability to transfer heat. WaterWetter will help with heat transfer, offers corrosion protection and is not slippery like glycol. Here in Brightest Africa, we are not supposed to run gycol-based coolants in race cars.

I've seen reduced temps since using WaterWetter.

If the problem is persistant then a larger pulley for the waterpump may be a cheaper thing to try than a bespoke radiator.

If it's intended to do its job best at 2 - 5k rpm and you're keeping it above 6k for prolonged periods then it might be cavitating rather than moving the coolant around.

Cheers all.

I'm going to get some Wynns to flush the system to get rid of any 'cr4p' in there and then will give Water Wetter a go with some distilled/de-ionised water.

We use WaterWetter over in Dubai for the race and desert rally cars. No issues with overheating in either of the EP3's or Clio Cup car last season.
