August 29, 2008 - Something else that showed up in the rereading of the regulations was that the car should not have antifreeze in the cooling system. This is fairly common with race cars because antifreeze is really slippery stuff. I should have thought of that. So the coolant was drained and refilled with straight water and Water Wetter. It's a water pump lubricant (as per the regulations) that also drops the surface tension of the water to avoid spot boiling. According to the bottle it has all sorts of magical properties, and it really does work according to some testing we've done at Flyin' Miata. It's also the coolest color. tags: cooling |
