I can one up you. Just as a rough guess, how many guys today do you think dyno their engines today? I’m betting it’s way under 10% and there are a ton more dyno’s out there today then there was when those books were written.
Just as a rough guess, how many guys today do you think actually can test at the track and do it even remotely accurately? i suggest that I’ve been to the track enough times with guys to help them and maybe 1% of the time they make 3 good enough passes to assess a single change. I’ve seen guys who couldn’t do the same thing twice in a row. So how do you evaluate that?
So put the two together. Back in “the day”, those guys didn’t use a dyno. Most of them didn’t test, and if they did, they didn’t do it well. So taking what those guys did back then has to be taken with a 10 pound bag of salt.
BTW, they shouldn’t have any argument about rings and horsepower. That’s been proven so many times it’s silly to even dispute the fact.
