LOL I know Scott can understand it. Well, you're on the right track my friend but I don't think it is heat. I think the original calculations were off. The boost is not changing with heat. With the 2.2" pulley (rated at 9psi), we are seeing about 13psi. With the 2.0" pulley (rated at 10psi), it is about 15psi. I've run every pulley size from 4psi up to 8psi (3.2"-2.4") and have seen differences in the boost readings on the gauge. The only proof I have right now is reading the gauge and knowing that it has not been adversely (or increased boost readings) affected due to heat. The heat will decrease the amount of burnable O2 because the air is expanded but the pressure will remain the same. I'm not a physisist (and probably can't spell it right

), this is just my observation.
At 2.2" pulley size, we are WAY past the rated speed of the TRD/Magnusen supercharger. Again, this is uncharted territory. TRD did not do this and Magnusen says it shouldn't be done (but it can). Do the math, the crank pulley is 6.0" and I hit as much as 6,400RPM. I know that for a fact and it is exact. It's the same as everything else - experiment and if you brake it, find another way...
I'll be able to prove it a little better once all of the work is complete and the break-in is complete. I'll have an intake temperature gauge monitoring the sc housing. I can see the difference just by turning water injection on and off. Plus I'm sure I'll see a difference when I'm squeezing the bottle and when I'm not. I'll be sure to post what I find as always. If possible, I'll even push to the 2.0" pulley running 15psi. It all depends on the temperatures. I'm not going to do anything stupid. For that matter, if I think the temps are too high at 2.2", I'll back it down to my 2.4" pulley.
Hopefully you guys know me well enough to know by now it isn't bragging, I'll tell you the bad with the good. The first bad I had to report was I pushed the boost past safe limits and damaged the motor. I know there are people out there running 7psi and have no problems, I say they are the lucky ones. I pushed it to 8psi but I'm pretty sure by the indications that it was damaged at 7psi. I think 6psi on stock internals is the safe limit. Even 6psi should be done with the right fuel mods. I've learned a lot here on the forums and always want to give back what I learn. -JoeB
