Funny thing is that I was just looking through those two books for some info on cold air's effect on power. Turns out its in Urich & Fisher. But while skimming through I noticed I noticed he didn't really understand how the low speed/idle circuit worked. That's the thing. He was a great writer and had enough freedom to do some interesting independent tests that he then shared in his books and articles. I think that's part of the charm of his books, at least his earlier ones like those two, we're learning with him. But that's also a cautionary point with Vizard, which I've detailed previously if someone wants to search it out.
