Common logic knows nothing.
There is no flow thru the reeds and thus into the case around BDC.
Flow in most all reed engines isnt initiated until TPC on the upstroke, this is when the reeds have finally opened enough for flow to start.
Thus the most effective intake strategy is to have as much area as is possible at TDC, and as much area as is possible via floor and
Boyesen ports.
Holes in pistons are best as low as possible, along with the biggest piston cutaway as is possible to reduce port masking as it rises and drops from TDC.
Here is a typical ( my TZ400 at 11,000 ) cylinder reed intake mass flow and Mach.
Ive got a thing thats unique and new.To prove it I'll have the last laugh on you.Cause instead of one head I got two.And you know two heads are better than one.
