The speeds were 60MPH....those numbers are an average also, of course at different speeds and different PSIs the numbers changed, but it was interesting to see that the TMIC cools as well as it did.
And you can find it as hard to believe at 220 temps if you want, but I'm just posting what we found. His filter sits where the stock airbox was(no cold air box between the top Rad line either, so that may account for some extra degrees too)...

I dont even have the luxury of having the filter sit that far away from the turbo.

Well if you IC is efficient that shouldn't matter that much...

It wasn't just at 60. I started at a stop light and took it up to 100. I know that these sensors are pretty accurate because I have tested them (boiling water, gauges read between 209 and 215.).
150 degree temps are really hard to believe. It gets that hot if you just rev up the motor. The air coming out of my Type-S is at least 150. Are you talking about intake temp (before the turbo) or before the intercooler (after the turbo). The turbo heats up the air alot because of the exhaust being right there. That would tell you the thermal efficiency of the turbo (if a sensor was also placed after the compressor), not the intercooler. I have one sensor after my BOV, and before the TB. I need to see if removing the metal duct underneath the intercooler has helped at all. I will put it back on and see how it runs.

I will do it on my way home (30 minutes to go). I've done so many different pulls, I really can't remember all the numbers except for the highest ones. I know that when you floor it from first on up, it changes about 4 degrees a second from around 120. At higher speeds, it does not start to creep up, at least not at 100. I'll go higher on the way home. I'll post back in around an hour. I will also post some pics of my setup.

Here are some pics. The first one is of the sensor setup. You can see the first sensor after the BOV and the second before the TB. The second pic is of the sensors and the readings I got after a 3rd gear pull. I started at 1500 rpms and took it up to 7500. The one on the left is before and the one on the right is after. Oh yeah, I was also running 7psi.

Alright, I just got home from work and I just ran a 3rd gear pull from 2500 to 7500. Boost was set to 14 psi. Temps were 239 before and 139 after. The air temp was around 95. The metal duct underneath the intercooler was also removed.
