GT350 IAT on track?

[YellowJacketBoss302]

Aynone datalog IAT in a GT350 on track? At highway speeds (75 ish) I see about 10 degrees above ambient. In the BOSS IAT was about 1 degree above ambient at 75.

I haven't but I've been taking photos of my temps coming off track. I've noticed my diff running very hot. I have a thread with photos somewhere here.

I've been watching mine, and with the stock gt grill I see about 10-12 above ambient.

I data logged mine last week at Barber. It is averaging about 15 to 20 above ambient on track. Much higher than I expected. It goes up considerably at WOT. Given that the engine is ingesting more air at WOT, I thought IAT might actually go down then. It does NOT. The IAT sensor appears to be in the intake tube right near the air filter. So, some insulation around the intake tube and air box might be in order.

Looked more closely at the logs. Average difference between IAT and ambient was 14.3 and the max was 23.4. I have added some insulation to the intake air tube and will have some added around the air box before the next event.

I am wondering if modding the air inlet to the air box in the other thread would help lower IAT and maybe provide some more power since it seems pretty restrictive.

@blok welcome to TMO. It might help, give it a try and let us know how it works.
