Don't read if you're close minded
All these HIGHLY ANECDOTAL and THIRD PERSON...three times removed....accounts of guys talking about how dyno results don't translate to real performance. Lolz.
Couple points....
1. Dyno tech has definitely progressed since freaking 1970. Am I saying that the tests done back in the day were all garbage? No. But if you pick up over 100 HP and go slower... something is off in the combination. Or something was flawed.
2. All...ALL of the major racing teams today rely heavily on the engine dyno to test and evaluate changes. Serious efforts will have race courses programmed into the dyno to simulate real world dynamics.
3. Yeah that Boss 302 couldn't be made to work for road racing lolz
