Best coolant to use?
Had a track day yesterday and for the first time I over heated the engine (twice!) and had to cut a couple track sessions short. I've heard great things about Engine Ice, Water Wetter and Motul Mocool. From what I've heard/read Engine Ice is the best. Anyone else have experience / suggestions?

The best coolant in my experience across multiple platforms and multiple venues of automotive competition/hobby is distilled water with a little water wetter for anti corrosion and anti rust. THIS IS NOT FOR FREEZING CLIMATES!
It happens man, upgrade your coolant and think about adding some coolers. Add an oil cooler and the oil stops heating your water

The ZL1 does have OE oil cooler, but it uses the coolant loop (ie radiator). For track purposes I would suggest to separate those two. It will also help with oil temps.
What temps were you seeing on the coolant? What was ambient temp? Sent from my iPhone using Tapatalk

I've tracked this car for about a year including last summer and never ran into this issue. However since last summer I've added a slightly smaller upper pulley and as such creating a little bit more boost. However looking at Eaton's efficiency map for the TVS 1900 I really shouldn't have lost much efficiency up high.

Granted I don't have a ZL1 but I never had overheating issues until I went to Fontana on a super hot day and with all the long straights there I got the overheat warning. What I did was install a 165 tstat and installed a large oil cooler split from the coolant loop. last time out to Fontana before I moved I was maxing at 265 oil temp and never saw over 220 coolant temps

Man I would get a good air-to-oil cooler set-up like I did, all your problems will be solved. Those oil temps scare me. My dual air-to-oil coolers keep the oil very cool, and eliminate the coolant-to-oil lines that went through the radiator, so the coolant only has to cool the coolant. I think a stock radiator would be more than sufficient if you did this. You may have seen my thread, but here it is...
