i don't know about the horsepower per dollar equation, but that kind of power in the vid would only be useful on the strip or street anyways. you can't see the rpm scale on the bottom, but it looks like the real meat is pretty far over to the right @ 4-5k rpm.

I feel how HP is measured has changed over the past 20 years. Take that exact same motor and put it in a time machine back to 1990 and NO WAY it has 500+ HP. And I don't mean crankshaft vs wheel HP either. It's pretty common to hear people throw around 1000+ HP which is complete BS 99% of the time.

yes dynos are tuning tools and it's easy to fudge numbers. but if that jeep makes a pass and traps 125+ there isn't much to say.
