Coolant- What To Use?

I know this isn't helping with answering your question with regard to a water additive. A great question by the way but I thought some might find this interesting. I agree the track could most likely help out if you call them.

I had the pleasure this weekend to spend a couple hours speaking with the mechanic for Street Outlaws Chuck Parker at Firebird Raceway in Eagle Idaho. I asked about coolant and he said there are no water jackets or coolant in these cars. They start up, do their burnout, hit the 1/8th mile in less than 4 seconds, chutes out and they shut them down and tow them back to the pits. Block temp is around 130f per the data in the computer at shutdown. He told me the car cost around $350k to build! And yeah, I guess the engine is some sort of hemi...I forget the brand of the block, I had never heard of it but then I don't build cars that cost $350k LOL
