You may be surprised, .. the "grump" is a fairly smart guy. I don't know if he uses all the flow ratios and coef stuff, .. my cuz works there, I'll have to ask.
But yea, things have changed. In the 80's I was offered a job at a few NASCAR teams, .. now if you don't have a degree in engineering they won't talk to you, . no matter what you've done in the past.

From everything I've heard & read about/from him, I'd say Da Grump's an extremely intelligent individual w/ an exceptional ability to think "out of the box". I'm sure he was back in the '60s & '70s, only things were a lot simpler in terms of what people knew and had to work with at that time.
BTW, what sort of flow bench do you have? You're less than an hour's drive south of me (I'm in Sterling) and would be interested in doing some comparisons between what I've seen on my SF-110 vs. a "higher horsepower" bench to see how much variation there is between results converted from 8"-15" H2O vs. results from a consistent 28".
