Careful with that open mind, something might fall in it.

Output shaft of the rotary turns at 6000 RPM...hmm?....about the same as 
a leaf blower's compressor.
You know, those bigger leaf blowers deliver 600 to 1200 CFM at around 
180MPH.

There's some space there between the flywheel and reduction unit's 
mounting plate.  Possibly the same as one of those compressor plates? 
The stock engine comes with several sheet metal plates that turns the 
rear housing into a round shape.  You'd also need a round adapter plate 
(Tom Belvin is working on mine), and a way to complete the shroud 
(fiberglass is our friend, or do I improve my sheet metal skills?)
Added weight? 3 or 4 lbs, maybe.  Sure beats 30 from a turbo.
No special handling of the hot exhaust.  Better yet, direct part of that 
pressurized air backwards through the EGR passageways, and dump it into 
the down tubes just after the exhaust exits the block.  Cool the exhaust 
AND bring it back to subsonic speeds.  The muffler will thank you.
Overcharging the intake.  A centrifugal compressor at 6000 RPM will 
develop pressure, but not so much that it couldn't be controlled with 
throttle...I think....err?...hope?.  It'll need to be tested.

Which is probably the most key point.  I haven't built it, yet.  Let 
alone tested it. . . .but, any month now. . . .
