Penrite oil for track/road car with forged bottom end

Water Wetter ordered.

After a top hose popped off recently in the pits at the track (loose clamp?) and was topped up with water only, the coolant system has probs only water or 95ish% water in it.

The car is based in Melbourne so not sure I need much in the way of antifreeze, but what else should there be in the coolant system as well as Water Wetter and tap water?

I've used water wetter, didn't make a huge difference. I've gone back to regular coolant (Castrol) and distilled or filtered water. I'm sure though that when the cars go in for service it's probably tap water.

Another can of worms, coolant

However, cleaning up of a ethylene glycol based coolants is difficult and leaves the road/track slippery. Motorcycle riders hate coolant spills especially on the track.

There is a small amount about cooling here http://www.mx5club.com.au/index.php?ID=8 from the MX5 club of WA.

Instead of tap water use distilled/demineralised water.

I will be going water wetter once I fix a niggling coolant leak.

It will work best with pure distilled water. Glycol actually has less cooling ability then water, but is a liquid across a bigger temperature range.

Tap water had a lot of additives that you don't really want in your cooling system

If your cooling system is all good you probably wouldn't notice the difference though.

As Mapie says coolant it's slippery and hard to clean up, hence why some race series mandate no glycol based coolants.

For coolant in track only cars, I use Nulon 'Ultra Cool' - no glycol & is recommended for motorsport use.
I use distilled water & add some water-wetter to the mix.

Ultra cool & water-wetter don't have any anti-freeze properties, so when parked overnight in the carports at WP in the middle of winter I put a towel or blanket over the engine, & a cover over the car.

There's a power point in every one of the Wakefield Park carports. You can park there overnight and run a lead to a small incandescent lamp under the bonnet. That will protect you against anything the Goulburn climate can deliver.

I have 230,000 miles on my 2004 Mx5 Mazdaspeed! 1/2 of that drag racing, autoX & drifting! I follow NHRA teams. 1day = change. 4 quarts = cheap! That track oil goes into my 05 Mx5 daily Driver Mazdaspeed 130,000 miles with 1/2 new oil. Both IHI turbos have NO shaft play!

That's actually a pretty good idea for keeping the oil fresh in the track car and accumulating a free(ish) supply for the tow car. Thanks for that, John!

Yeah, not really. I did that with my Zed, using Agip oil and then dumping that oil into an XB falcon that I paid $300 for so it didn't matter.

The motor in the XB didn't really like the contaminants and sh*t that came out of the Zed, even though it was only two events old, or a couple of hundred km at most on it and the oil looked clean.

You just don't know what sh*t is being picked up in the oil of the "good" motor to risk the other motor.
