Actually, much of what you posted is incorrect.
First, The M62 does NOT cool down as the pull goes. Intercoolers do NOT get more efficient as the pull goes on and the M62 continues to get more INEFFICIENT as the pulls goes, which increases the heat whether it's IC'ed or not.... Further inefficient and further off the compressor map...
Second, compare apples to apples. What MOST have easily available to them is a non-intercooled version oft he TVS and a non-intercooled version of the M62. Again, Most... If you've done much boosting with those two blowers without an IC, you'll know that the delta T of the M62 at 7ish psi on the 2zz is about 120F. At 10 psi it's around 170 or greater depending on the engine. The TVS is 100F at 10 psi. That's fully "heat soaked"...
Third. Real testing? OK, I've got 40 some odd dyno pulls on the M62 at varying boosts from 7psi to 10psi. I've got a few thousand track miles on that blower and much of it data logged with redundant sensors on a DL-1. I also have a few thousand street miles on it and have data logged those conditions at times. That's just on my car and not including clients' cars... I'm quite familiar with the non IC'ed M62.
Furthermore, I've got about a 1,000 track miles on the TVS. I have about 35 dynojet pulls on it (just my car, and not including clients' cars) and I have several continuous hours with the TVS on a mustang load sustaining dyno (again, just my car). Much of that time is data logged. Some of those track miles were at 100+ ambient temps. I'm equally, if not more familiar with the TVS. You, sir are not, and that's evident in the numbers you posted. No flame intended, just stating the facts.
Go back and read through my posts. You'll get your numbers updated and will avoid this confusion. The FACT is that the only way you can pull off 10psi and make sustainable power on the M62 is to intercool it, as the blower is hellishly inefficient at that level of airflow on the 2ZZ. If you have the means to IC the M62, then go for it.
A ~50% efficient IC on the M62 pushing 10psi pre IC, will yield about the same power as NON IC'ed TVS at 10psi. That is a reality that exists and has been tested on the Lotus...
Of course, if you're going to go through the expense to IC the M62, it would only make sense to put a real blower like the TVS in front of the IC:wiggle:
Below are pics from a multiple hours on a mustang. Last pull of the day with red hot headers on 91octane fuel: 285whp... Darn heat soak.LOL
