Thought of water spray'n the TMIC ? ...might help a lot.
I'd like to see a WAT IC that would work well in that situation...but in my experience they really don't work that well for track type stuff unless you have a massive radiator in the boot, WTA resists getting hot quick but once they are hot they run a higher ratio above ambient than a ATA and will not cool down very quick like a ATA.....big advantage with WTA comes when you use an ice reservoir or such
Go FMIC lol !
