H
so let me get this straight:
horsepower, a unit of measurement which was created in the 18th century solely as a marketing gimmick and which is a literal byproduct of torque (and RPM), is today considered more important than torque, even though torque is how engine power is actually measured

Dude airspace engineers use feet as a measurement unit

So use niggawatts commie
Ever heard of free speach?

do the space shuttle door gunners do that as well?

Torque is an instantaneous force from one power stroke.
Horsepower takes engine speed into account (more power strokes at higher rpm can mean more acceleration even when torque starts dropping). Whether the unit is arbitrarily based on a horse or whether it needs to be calculated instead of measured does not mean it doesn't mean anything.
Picrel, a (probably modded, but doesn't change what I'm saying at all) Honda K20, famous for accelerating only at the top end, has a flat, slightly downward torque curve at the top end.

Would you rather drive a car with 1000hp and 500lbft or a car with 500hp and 1000lbft?

That depends. Am I racing of off roading?

> torque is how engine power is actually measured
no, torque is not a unit of power. torque is like a unit of work, and power is how many units of work can be done per unit of time. That is what horsepower is.

from plebbit
>Torque = Damage per hit
>RPM = Attack speed
>Horsepower = DPS (Damage per second)
so what you really care about in terms of acceleration is power.

Torque is just force over a distance.

Which why a longer lever means you can lift more, with enough room.

You're an idiot. Horsepower is literally how much power you can make, and torque is a meaningless unit indicating where in the RPM range the most powerful single explosion in the cylinders is happening. It's meaningless because your engine does this more than once, and the end result of this is HORSEPOWER.
So more horsepower always wins, if your gearbox will let you rev to where it is.

define "power" in this context

Torque hauls trailers. Power wins races. You're not gonna go fast in a tractor.

torque is a general engineering term informing pressure/tension under load at the pivot referenced by a torque to yield ratio
horsepower is exclusive to ICE >>28823238

Try street driving a 1000hp with the most aggressive camshafts imaginable and a massive fucking turbo, then report back how torque is meaningless.

*a 1000hp honda civic
>>
>>28830025
could you even drive that on the street
not to invalidate your experience but it would be loosely comparable to the formula system
they don't drive on the street because they can't really be driven at street speed
does such a civic even have a turning circle compatible with the average street corner
>>
>>28823389
The latter
500 horsepower is honestly too much for a passenger car. You don't need more than 250
>>
>>28823238
You can have all the torque in the world, but it would be useless in a lot of applications if the motor can only spin at very low RPM. So horsepower gives you more information about the usability of the motor.

i drive an AP1 s2000. 240hp (allegedly) and 2700lbs scared the shit out of me at times.

for you retards, horsepower is equivalent to kilowatts. it is a measure of total energy being produced by the system. want to go 30mph? 1st at 6000 or 2nd at 3000. same speed, different power numbers because of the torque applied at that specific RPM.

drive your damn car and stop talking about numbers. it's more fun behind the wheel than keyboard
>>
>>28830025
Nobody said anything about street driving. From a purely hypothetical and performance standpoint hp is the only unit that matters. Lack of torque can be made up for by "shorter" gearing, and the idea is to keep the torque band as close to peak hp as possible. Literally nothing else matters from a performance standpoint.

You wanna talk street cars, EVs slap every dick imaginable of every ice shitbox on the road in every metric possible.

no, spacespace engineers use door gunners only on the third Saturday of the month. How do you not know this?

Yes. That's the scientific definition of "work".

i'd rather take my analogue roadster with cable throttle and no traction control than a >4000lbs computerized conglomerate of pure disappointment and misery.

doesn't have to be logical. my s2k will never come close to a Rimac Nevara.

don't care, engine loud, make car shake.

Horsepower is the application of torque over time
Torque alone is meaningless

Stupid comparison no one older than 16 years old wants a 1000hp car.
Better comparison would be 150hp/450nm or 300hp/300nm.
>>
>>28830705
An even better comparison is 300hp/300 lb ft of torque vs 300hp/150 lb ft of torque.

If torque doesn't matter then there won't be a difference.
>>
>>28832288
Nobody, at all, said torque doesn't matter. Its curve doesn't represent acceleration as well as horsepower's does, but it's very real. For the record I'd take the 1000 hp, 500 lb-ft one. I literally have a 470 hp / 975 ft-lb truck less than 10 yards away from me and it excites me very little compared to my shitbox with maybe 100 lb-ft.
