I wanted to know what one considers to be a safe IAT in ambient temps of 90F... if I run my TTS to 145 mph and the IAT tops out at 113-115F is that okay or do I require better ICs.

I would be interested to hear from anyone like Terry@BMS, ALEX@ABRHouston DZenno etc that has technical and practical expertise in this area as I am reading some 997.1's are hitting 125-130F and higher and not having a dramatic drop off in performance at lower speeds.

My car ahas stock 996 Turbo ICs, I would be going to ETS or the 997 GT2RS which are both highly rated and have pluses and minuses as to weight/performance/cooling effect.

I am hitting some great times for stock K24 turbos but have been getting some 1133 codes on occasions (O2 sensor overheat etc)
