My point: It's real easy to take an engine off of a 40,000 dollar dyno, strap it into a 15,000 dollar car and figure out how to go slower than the dyno numbers showed it had potential to run.
This is what I get touchy (fair or not) about. If you feel a speed/weight/HP slide rule or online calculator gives you a fair amount of information to discredit a dyno, an engine builder, or a dyno data sheet, you are doing the equivalent of someone using a crescent wrench as a hammer.
I agree that there are a lot of ways for an owner/car to make hp semm to disappear. But I have seen a motor go from one dyno to another and there be a 40 hp difference. Both well known reputable shops.
