Default Intake Air Temps

Anybody running an M45? What kind of IATs are you seeing? I have an Autometer Air Temp gauge with the probe installed in the crossover tube just before the dummy TB. It seems to hang around 150 F when NOT under boost even in cool weather. This SEEMS high to me but perhaps not. I plan to check the accuracy against a digital thermometer at some point but thought I'd see if perhaps this is just typical. ???

seems about right if you are scavenging air form the engine bay. I've seen stock miatas clock in around 130-150 once the bay heats up.

Thanks for verifying. Guess I need to find a way to get cooler air in. I just hate to waste too much time on it when I plan to turbo next year.

Think moving the air filter up behind the headlight would help? I thought about getting the DDMWorks cold air box but I'm trying to avoid spending money on anything I can't re-purpose for a turbo.....hmmmm, maybe I COULD reuse that?? Anybody near central Ohio have one I can look at?
