Why is it that every time people talk about wheel hp vs crank hp, the wheel hp is always significantly lower than crank hp? Like, a 250 hp engine can only put out like 160 or so hp at the wheel, presumably due to drivetrain losses.
Why hasn't anyone made a system where the drivetrain actually adds horsepower? So an engine could make 250 hp at the crank but put out 300+ hp at the wheel? You'd get way more performance out of cars if you actually gained power through the drivetrain.
>tuned GTR makes 1200 at the crank
>800 at the wheels
>a civic makes 110 at the crank
>80 hp at the wheels
makes you think.................

Veeky Forums posters, ladies and gentlemen.
>has never heard of turbonique
OP needs a drag axle
>running above 100% efficiency
Fuuuuuuck
> Percentages, percentages everywhere.
>why don't we just ignore thermodynamics
It's not above efficiency if another system is making up for losses dunderhead
what if we put the civic trans in the GTR, that way it will only lose 30 hp not 400
You're retarded
Everyone can call you a retard but none of these retards can answer the question...
(Why hasn't anyone made a system where the drivetrain actually adds horsepower?)
Let's hear your brilliant plan, user
Because you would be creating energy from nothing, which is literally physically impossible to do.
The only potential option is an electric motor supplement, but at that point the weight of the batteries and motors would probably negate a lot of the gains while making the vehicle cost a lot more both in the short- and long-term.
Well seeing as we're talking about at the crank vs at the wheels we've already passed the combustion part numb nuts.
It's all mechanical loss because the power has to go from the crank to the tranny into the driveshaft then through the diff into the wheels. At no point is there any thermo related losses.
Stop being a fake engineer
WHY ARE THREADS LIKE THIS ALLOWED
>why hasn't anyone broken the laws of physics
Not them, and while I usually hate getting nitpicky, technically at any point that any drivetrain part makes contact with literally anything else, friction is occurring and a by-product of that is heat, obviously in varying levels. So while direct mechanical loss is probably the biggest offender, energy is still lost in heat in the drivetrain.
Honda engineering wins again

I guess that's true. Just ass mad when people pretend to know what they're talking about.
May I ask, are you high right now? How many bong hits have you had?
But the engine will always be the source of energy for whatever "system" your drive train is using for more theoretical horsepower
WEW LAD
not if you add more energy sources in the drivetrain
Why not add reverse reduction gears at some point in the drivetrain, so the driveshaft spins faster than the crank, making up for the loss in hp?
So like a 1:3 final drive?
What the fuck is the first law of thermodynamics, faggot?
Within it's inertial reference frame, and object in motion tends to stay in motion, and an object at rest tends to remain at rest, unless acted on by an outside force.
Not sure how that applies to this.
"ore specifically, the First Law encompasses several principles:
The law of conservation of energy.
This states that energy can be neither created nor destroyed. However, energy can change forms, and energy can flow from one place to another. A particular consequence of the law of conservation of energy is that the total energy of an isolated system does not change."
TL;DR:
You cannot create more power than the one you recieve without drawing power from somewhere else. Energy cannot be created nor destroyed.
You cannot have more power going on the wheels than on the crank without using something like KERS or something that uses extra power. But assuming we are talking there is no KERS there is no physical way to do such thing.
Its like the perpetual motion machine. It violates the laws of physics.
What a strange idea... We could call it... Overdrive?
That's an overdrive ratio in the transmission, present in all modern vehicles, and it can't affect power, only torque.

That's how retarded you are
I don't know I'm trying to figure out the thermal efficiency of my bong.

It's called a hybrid.
