I have no worries about the engine overheating, Its me sweating to death thats the issue. I see your point about summer tuning but with no a/c, I don't drive the car that often july through august. I usually do early morning drives in the summer. I may have the turbo back in two weeks, so I have some time before the no drive months. Or right after a monsoon blows through and drops the temps 15 degrees. lol
Maybe I can get one of those old school tube shaped coolers, that hung on the windows of cars in the 50's or VW Bugs i see out here.
