I am fascinated by this subject, and I can see it going either way, frankly.
I am also wondering if the elevated cylinder pressures in a forced induction motor might behave differently from a normally-aspirated motor under these circumstances.
I'm interested as well and would like to see results of test OP proposed.
IMO, a forced induction motor would have to behave differently than a naturally aspirated one. At a given rpm, there are X lbs of boost that is going to try to fill the cylinder as soon as a valve is cracked open. A naturally aspirated engine on the other hand will gain volume drawn in as piston approaches half-way down and will slow down its draw as the piston approaches BDC of the stroke.
This is assuming valve timing remains constant. You know better than I how a cam that is optimized for forced induction is different than one for a naturally aspirated engine.
