Where I’m seeing 160-170 in 70 degree weather with no isolated system, even with one I don’t think I’m going to see 105-113 under WOT. Just last night, it was 58 degrees and under WOT I hit 145 degrees.
I agree that all the cooling mods you can do - are a must if you race or drive aggressively. Or else clamp the IAT sensor to the ECU with a resistor to prevent timing from being pulled out from under you.
I see the highest IAT's after I shut the engine down and fresh air is no longer circulating thru the intake system and around the HE. - I would think that 1/4 mile racing would be the worst because it's all boost - back in line and shut it down. ICE on the SC (and Y-pipe) is a great trick for cooling the intake system down - a must if your wait time between runs is short.
I found that having the IC pump wired to run when the key is "on" allows the coolant (when split from the engine) to flow and dissipate the trapped heat.
I can't tell you what type of IAT's the 185mm produces from ambient OAT to WOT during a 1/4 mile run - but I will be able to tell you how much heat it produces during a 1 mile WOT run. Hopefully I can data log 15 one-mile runs.
