I was searching for a thread that has any information about flow testing all these porting that I see on this forum or any rotary forum, but can't seem to find any not even on google.

I'm just wondering how come this is not common on the rotary engine, I mean without some kind of flow test, any one can claim there porting is super good etcetc...

does anyone have any real data that there porting or port template works? flow test that show that the port actually increased flow.

I remember one time I found something about a flowbench for the 12a engine but can't seem to find it anymore.
