The rise in intake temps may be mostly due to your SRI drawing air from under the hood and behind the warm radiator rather than from outside the car. While the top mount IC may be contributing to the ultimate problem, I would think your IAT's would be lower if you were starting with ambient 95 degree temps going into the MAF.
I believe your MAF sensor reads your IAT's at that point in the system. That's before the intercooler. Your BAT's, which you should be able to read on your AP, would tell you what the temps coming out of the IC are.
But your IAT's set the stage for BAT's. If the IAT's go up one degree over ambient, your BAT's will also be one degree higher than they would have been.
For every 10 degrees of increase in IAT or BAT, you lose 1% of your horsepower. With an IAT of 149, you are down over 50 degrees, over 5% of your available horsepower.
I'll bet that even after you get underway and get some air being drawn into the engine compartment, that it takes at least 15-20 seconds before you start to see the IAT's starting to fall back toward ambient.
