I've done the same thing he was talking about many times.... trial and error works well and seat of the pants feel can also work well but I will generally use a stopwatch along with it.
yes they made them that way to make up for boosters blocking the air flow. some tested the 800 cfm and it did not flow the 800 cfm. just because a company makes a statement is it always true ?
That could be. I also wrote programs on an old Hardinge CNC machine while I was working my Machinist/Shift Supervisor career of almost 50 years, for metering rods and jets. This machine was so old, it was controlled by a mylar tape, which had all the G-code commands as holes punched in it in controlled patterns. the jets were made from round and hex brass rod, while the metering rods were made from brass wire as a straight piece, then the ends where they attach to the rod "tree" were bent on a fixture i made up, so the rods were the correct lengths where they insert into the jets, and attach to the "tree". I saved those program "tapes" and tooling sheets, but that machine is so obsolete now, there are few, if any, left in operation.
I ran an old NC machine that was programed with one of those 'holy' mylar tapes lol. The memory bank (Fanuc iirc) had the capability to edit and spit out a new tape. Our programmer really sucked. That was back in 79. Was making oil field parts though.....That could be.

I know where there are a couple that are probably still running.That could be.
