Owning HP wakeup call

It actually comes down to only one thing.....RPM.

Because horsepower can NOT actually be measured.

Horsepower is how much torque can be applied in a given time.
Taking this a step further, while absorptive resistance dynomometers work by directly measuring torque, no one is using them to measure the horsepower of a car. They're used for measuring horsepower of electric drill motors and vacuum cleaners, the oft-quoted "BHP". By contrast, the inertial dynometers used for measuring cars measure acceleration of a known load, from which you can directly calculate both horsepower and torque. The torque equation is a direct analog to the F = m*a you learned for straight-line acceleration in high school, but with fancy Greek letters representing rotational acceleration, moment of inertia, and torque.

Love this guy. He's so smart and easy to follow.

Not a bad video at explaining exactly what a "horsepower" is and why its a good way to compare two engines, tractors, trucks, etc.

But the end just turned into a american vs metric and why metric is better.

But ALOT of things are dual rated....both kw and HP to appease all parties involved (y)

My mx is listed at 52.2 gross engine HP.....and 38.9kw.......math works perfect....1hp = 746w

Coworking from the UK was talking, I guess "a thing" among him and his friends was owning 1,000 HP by the time they were 40. Didn't matter how many engines or what type it took to get to 1,000 HP. Of course I had to start calculating...1,569 HP was what I came up with. Pretty respectable but then I counted all the engines it took to get there, 21. Three are purely recreational (dirt bikes for the children) but all the rest are for work, kind of shocked me a bit.

So figured I'd see what numbers everyone else has and if you think there's anything you could cut or want to add?
1965 Bridgestone 50: 9.5 hp
1958 Willies truck :115 hp
1970 Boa ski : 2.8 hp
1968 MGB : 95 HP
1967 C10 :300 HP
1970 Buick : 315 HP
1977 Monte Carlo : 300 hp
1978 Scottsdale K10 : 420 hp
1984 MonteCarlo : 420 hp
1992 Jimmy : 200 hp
1998 Tahoe : 300 hp
2004 GMC 2500Hd : 330HP
____________
2,777.3 HP ?
No calculators were harmed in this equation. Only a small old brain.

Knock 70 hp off that. Wish I had all the fuel and tires I burned up with those.

Haven't added it up yet but:
'00 explorer 225hp
'98 Explorer 225hp
'90 Ranger 220hp
'97 Ranger 107hp
'97 F350 225hp
'03 Camry 170hp
Kubota L260 26hp
That's 1198hp with just the easy math 4 wheeled stuff... I dyno engines all the time, horsepower is kinda silly to me... personally I don't care too much, the '90 Ranger is just an estimate as it's a somewhat random conglomeration of parts, and I forgot to include my boat which is likely 230hp... and this list doesn't include the non running vehicles on the property :)
