Trying to reply to your pm, but apparently you have exceeded the maximum amount of msg's you can receive. LOL. Bet you never check or clear your voicemail either.

Wouldn't that just increase the IAT2s even more as it's being compressed twice? Guess I just don't understand how you can have 22lbs going into a blower while spinning the blower @ 8-10 and it working.

Only using the L intercooler or a air to air also?

Do you just use the waste gate to control boost or the boost actuator on the blower also?

Gotta admit. I'm a little addicted. Wife gives me hell about spending more time on the forum than with her. Only time it gets annoying is when my phone is getting notifications every 30 seconds when laying down at night.

Sort of. PV=nRT, temperature and pressure are directly related.
"The supercharger is not a stagnant, solid piece that air has to travel around or through. Rather, the supercharger is simply doing what it does, and that's take air and essentially make it smaller. The supercharger will simply take the air that has been compressed by the turbochargers and further compress it as it travels into the engine. In fact, the turbochargers will basically help to improve the overall efficiency of the supercharger. Roots and screw-type superchargers experience a condition known as "back flow." Back flow refers to air that doesn't make it into the engine when it is compressed, and actually comes back up into the intake tract. This air is heated, and is the cause of the loud noise heard from positive displacement superchargers. When the turbos are added in conjunction with the supercharger, they help to keep the airflow directional, minimizing the amount and effect of the back flow. Also, it's important to remember that boost itself is actually a measure of restriction, so to speak. The number that we read as "boost" is positive manifold pressure, or the byproduct of the engine only being able to flow a certain amount of air through it at any given time. The air that is being forced into the engine will eventually overcome the amount of air that the engine can ingest during every revolution, and the resulting "back up" of air is positive manifold pressure, or boost. Therefore, by using the supercharger to create a higher level of pressure, it cannot be viewed as a restriction. "

I see what you are saying, logically it seems the blower would restrict it and the enginge would only see what the supercharger is blowing. But every rotation of the rotors just lets mroe boost in from the turbos.

It's super hard to tune and get boost pressure accurate with that setup though. Wastegates and BOV's have to be set accordingly. Although, you can mix and match it with the #'s of the charge to get optimal effects.
