How does peak power, power curve, peak torque and torque curve affect performance of a car or bike?

I'd have to write an autistic rant that would be oversimplified but would be multiple full posts. And I'm too damn lazy even to spergout about one of my favorite things.
Think of the power curve as a 3D map and all you see is the slice at the very end that's 100% throttle, the back right wall of picrel essentially.

horsepower is everything, torque determines where in the rev range your horsepower is. highest peak horsepower determines top speed, average horsepower across the usable rev range determines how "drivable" a vehicle is.
>>
>>28889179
Correct.
>>28889186
Also correct.
>>28889208
Midwit retard, confidently incorrect.

Horsepower is nothing but the peak power output achieved at high RPM. It mostly determines top speed, and acceleration but ONLY if you can keep the engine near peak HP. In any actual driving, even flat out acceleration, unless you have a CVT or a 25speed transmission you're going to be covering a range of RPM. In that range, you want the most area under the curve possible. That's what makes it actually good.

Enginea that only produce good torque in a narrow band are useless in most driving applications.

top speed is purely determined by horsepower

>>28889379
Horsepower isn't real. Top speed is deter by torque and gearing

If you're just looking at an adjusted dyno chart, horsepower visually represents acceleration more.
Torque represents the instantaneous rotational force from one power stroke. Horsepower takes RPM (thus time, the number of power strokes in a given time) into account which explains why many high strung cars accelerate more after torque has already dropped off. Again, not considering gearing.

Don't forget gearing. Look at thrust

Yes they are called close ratio transmissions

>car makes 500hp between 8000 and 8250 RPM.
>Everything below is a wet fart.

Wow, so drivable, awesome!
>>
>>28889708
Not really, the peak of the curve is pointless, the width is what matters most.
Unless you got like 20 seamless gears or something.
>>
>>28889923
I agree with that, I understand integral calculus and gearing, but maybe you misread what I said.
>>
>>28889117
more is better and faster

>>28889117
Area under the curve in gear is what matters for performance. Anything above or below is irrelevant. People who argue otherwise are dumb.
>>
hp is just a given amount of torque at a specific rpm

When you see turbo gas engines with huge torque and much lower HP numbers, they are good engines that can make equal HP that matches the torque, but are factory street for emissions. Any smart tuner knows they can shift the torque curve up and make more hp
