How close does the unit get to the strut tower under full engine load? It looks like a fraction of an inch on page 1 to begin with...

It does not rub or touch under load - There is a good 1/4" of clearance if I had to guess (from watching when it was dyno'd).

Vortec is a centrifugal 
It doesn't move much air until the high rpm range. It is more for showing off high peak dyno numbers than real world performance.
The Eaton moves air over the entire rpm range - you have full torque from very low rpm ...

This is way too simplistic. Fact is, the Eaton has its own problems with efficiency, especially at high RPM (where we run our little 2.2/2.0l screamers a lot). So it does not exactly "move air over the entire RPM range". These things were designed for large, low-revving motors.
I'd love to see what kind of compressor efficiency is present at 8000rpm or so.

Considering this thing makes power all the way to redline with high ambient temperatures, I'd say there's not much of a problem with high RPM inefficiency.

^ I thought this unit spins to around 18,000 RPM, which I thought was right at the top the rotational / air flow efficiency. I believe there was a reference to where miata owners are using the same blower at 21,000 RPM, so there is apparently a bit of headroom, but not much. I am interested to see how this performs against the Rotrex kit head-to-head.
