Thanks Kinder, that will be phase two for sure

I finally finished sealing the box, and have some good data. Ambient temperature was 82, I logged without and with the lid on, and also with both front and rear AC on (wanted to simulate worst case)
IAT1 max value without lid = 127.4
IAT1 max value with lid = 114.8
IAT1 at redline without lid = 120.2
IAT1 at redline with lid = 96.8
Max Knock at Full Throttle without lid = .75
Max Knock at Full Throttle with lid = 0
Zero to Sixty without lid = 5.40
Zero to Sixty with lid = 5.28
The biggest take from this is the 23.4 degree difference in IAT with vs without the lid at redline, and the slightly over .1 second increase in zero to sixty

Very pleased, with time I will insulate the box to try and get closer to ambient.
