In all honesty, the CryO2 systems are designed as a means for adding power, not cooling down your engine bay. I would suggest switching out to an aluminum radiator, better flowing fans, 160* thermostat, and a vented hood. Also use some Redline Water Wetter. Stuff lowers coolant temps by like 20*. From there if you want to go really crazy with worrying about cool temps, I'd suggest getting your exhaust manifold/turbo exducer housing/o2 housing jet hot coated with the high temp black. Read the literature on it, it's pretty amazing stuff.
