Hmmmm, so Vizard has a video about raising the floor about a Half-Inch, for nearly 25% CSA drop yet gets record CFM, HP, TQ, discharge efficiency, and BMEP.
Then he shows how to reliably epoxy (Goodman epoxy, or JB-Weld was deemed okaay) the floor, and grind to new shape. Also makes the pushrod bulge blind straight view to the bowl.
If you could mold around a good cfm silicone Intake form, then raise the floor & straighten the bulge to bowl ( toss uniform CSA a first) then see what the CFM (and noise) yields.
That would be great.
