Right now my setup is working fine as far as coolant goes. I have to really push hard to get it above 200F and even in a stock RX-8 that is not hard to do this time of year.
My IAT's are a direct result of the fans pumping hot air onto the MAF. So as soon as I block off some air from hitting the MAF I am sure my IAT's will drop.

They are accurate I am sure. As soon as the fans were fixed (it was the fan on that side that was dead) the IAT's shot up. The hot air from the fan under the MAF pipe is heating up the piping and the MAF, thus increasing the temps. The IAT's at the TB don't really matter much right now since the ECU is reading whatever temps the actual MAF is seeing and making adjustments based on that. If the ECU sees high IAT's it can cause all kinds of weird issues.

true. How high are you seeing?
I have thought at times to actually move the maf section of the pipe outside the engine bay,
but then I open up the throttle and all that cool air comes in, temps go down and the smile on my face gets bigger.
If it gets too hot--watch your a/f's--make sure they dont get lean.
The maf is after the intercooler--right?

No the MAF is pre turbo. I have thought about moving it outside of the engine bay, I just don't know about extending the MAF wires even more.
The highest IAT's I am seeing is 137F or so. But I still need to drop the temps of the actual pipes in the engine bay and I think that will take a combination of coating, wrapping, and shrouding the intake piping.

The best place for the iat to be is post cooler--not pre turbo. But--you have to do what you have to do With a blow through system it does get tricky. Over my head really.
What I am thinking is his iat is getting heat soaked from the pipe--not the air within the pipe?.
Very true that hot radiator air from those hurricane Irene fans does need a shield though. Absolutely.
if the intake pipe is that hot then everything else is too.
Could some of the maf pipe heat be coming from the turbo? It is hot and they are connected....?

I have seen a picture of that mailbox before and considered that design on my own car. I just didnt have the room. True a different 'box" could be done--but what I REALLY need to do is to move the iat post blower. Tuning can compensate for the air temp difference--but that is not the ideal.
I do wonder what type of insulation you have in it?
