Power at 1500 rpm, 50% load.

>quoting specific output
>not specifying RPM

>>14062253
rpm is meaningless..

whp

the only thing that matters

>>14062288
Um, u wot m8

>>14062288
Come on man. The "specific" part of the term "specific output" (ie hp/L) is referring to the, get this, "specific RPM" that the cited Horsepower is being made at. Therefore RPM is not meaningless, but the entire basis for the existence of the 'specific output' concept.

>>14062314
No, torque

>>14062324
torque just makes you spin the wheels

horsepower makes you go

Torque tells you how strong your engine is, Horsepower tells you how hard it's working.

And the concepts cannot exist exclusive of each other in the context of rotating engines/motors.

>>14062335
sure, but horsepower tells you more information

Daily

Just think about little tiny asian peckers, they can be considered a high hp, low torque engine. Their little egg rolls might be tiny and flaccid, but there's billions of them revving at high speeds. This is how they sustain their populations.

OTOH Americans and some Europeans have bigger beef meat wieners with long stroke and lots of torque. Dames get pregnant just looking at the non-asian phallus, while the chinks gotta go fast like little jackhammers.

nice asspergers syndrome

>>14062322
youre a fuckin retard.
the rpm it makes it's peak power out is literally meangingless.

>>14062357
just like with engines

the asian sounds more fun

>the rpm it makes it's peak power out is literally meangingless.

you are retarded

making power at high rpm has several advantages

>>14062365
number of car per go= 1

>>14062382
no it doesnt.

>>14062388
except it does, given the fact that engines that make power at higher RPm have a bigger bore, they can fit larger valves, which means better flow

go read a book about engines

>>14062387
>car per go

wat

>>14062395
wat

>>14062395
you're literally fucking retarded.

hp/liter is peak power. it cant make more than that. what rpm is makes that peak power at is irrelevant. hp/liter is a metric for overall engine design.

>>14062414
>have two 2 liter engines
>one is undersquare and the other is oversquare
>the undersquare has a bigger bore therefore can fit larger valves

how is that hard to understand?

>>14062435
and yet if they are both 2.0 and one makes 100hp/l and the other makes 150hp/l guess which ones is better regardless of what rpm is makes it at?

ding ding ding the second one.

>>14062435
>not using sleeve valves

>>14062446
200hp @ 8000 > 300hp @ 5000

I own something with 82.5hp/L.
33hp/cyl

I am about to buy something with 185hp/L.
37hp/cyl

>>14062464
haha that is very very wrong

>>14062446
except its not that easy mouthbreather

with the same compression ratio, cam profile and time, fule and everything but bor:stroke ratio, the engine with a higher redline will make more power, simply because it can rev faster and has bigger valves, that at the same lift and duration, will flow better

>b-but muh torkz
literally irrelevant becase the transmission multiplies torque

>>14062464
you're thinking of torque. HP is power and is the same amount of power at any RPM because RPM is factored into the HP calculation.

Torque is just a rotational moment of energy. Torque at a higher RPM makes more power than torque at lower RPM.

>>14062478
higher revs are more fun

its making power for longer

so its better

>>14062501
have you heard of a transmission

you would need to actually look at the powerband to determine if it is making power for longer

it makes power from idle-8000 at the least

that is longer than idle-5000
