Yes. In one case 39hp on the dyno. So why isn't it "39hp" faster?

The guy I was originally addressing (see below) – which wasn't you BTW, so I'm not sure how we got into all this, LOL! Although you have also mentioned a couple of times that you can calculate ET and MPH etc from HP figures alone. But that's only using a standard formula that does not always...

Love your signature mate.

I think we all know that. Perhaps the next graph can better explain why torque is king. One engine makes more horsepower than the other. But which accelerates faster? Again, I think we both know the answer. Here's another one. Same engine with just a manifold change. The long-runner manifold...

Now, now. You know he can't read that because he put you on ignore. Until he takes you off ignore because he's too thin-skinned to contemplate that people are talking about him while he has them on ignore! Happy to dish it, but can't take it. That's weak.

LOL! I didn't "misunderstand" anything – I read verbatim what you originally wrote, which is a little bit different to what you have just posted. But still . . . If you would like to answer the following question, I'd be grateful. Which car accelerates faster: the one with peak HP or the one...

EDIT: Double post

I get everything. (Sigh, here we go again . . .) What does a dyno actually measure? I don't want to hear that it measures power, because it doesn't (only by proxy). A dyno measures torque and RPM and then converts that on a rolling graph to power. I repeat: a dyno measures torque and rpm...

The vector of torque can hardly be "meaningless" when that's exactly what torque is – a rotational force (that acts at 90 degrees to the centre, just like the opposite of centrifugal force). I also fail to see how it is "meaningless" when every single Power equation is based on it. And you're...

Thrust is a force the same as torque is force. Thrust is not "one rotation", just as torque is not "one rotation". That was the point of my analogy. But we're all good now. rpm = v because torque has a rotational vector. But again, torque is the force that moves, and rotation is simply the...

Well . . . there are other ways of multiplying the force. You could have a lot of torque at a low rpm and still produce a lot of horsepower. V8 vs 4-banger for example. There's also a reason why torque and weight are credited with breaking parts and not horsepower . . . because torque (force)...

Now you're on to something. So we agree that combustion produces a force which produces acceleration?

Answer: combustion (a force) What moves a car? Answer: combustion (a force) What causes acceleration? Answer: a force Is horsepower a force? Answer: No. It is a measurement of how often a force is applied So horsepower doesn't move the car? Answer: No. The force (torque) moves the car. The...

What moves a rocket?

So how does a rocket produce thrust?

Sorry. That's rocket science. If you truly believe that torque is "one power stroke" – as your signature attests – and not the force (combustion) that causes that rotation in the first place, then I can't expect you to understand rocket science. You already have combustion engines wrong.

A rocket engine has no moving parts – how do you explain acceleration of a rocket?

It's OK, I kind of figured this was going nowhere from the start. The earth revolves around the sun – it is moving – it is not accelerating. You confuse movement with acceleration just as you confuse Force with Power. No. Increased TQ made it go faster. HP is simply a MEASURE of the increased...

The reason I can't accept it is because the greater amount of force (TQ) being applied at any given rpm will accelerate the same mass faster. OK, my final attempt . . . You are in a turbo-charged car and you are travelling at 100mph holding a steady 5000rpm. To go faster, do you need to...

You were saying? Do please put me on ignore. It's a measure of the man who can't face reality.

Mate, seriously. Heat is just a measure of energy transfer. Potential energy is potential energy. It doesn't change. You can't create it nor destroy it – you can only transfer it or convert it to mass. I'm not trying to be a smart-arse, I'm actually trying to help people understand why torque...

Great memes. No-one's ever used those before.

I'm tired of explaining basic physics to people. You know the answer, I know the answer. Everything has been explained 10-fold in this thread. A 1000kW electric engine is a simple equation that disproves your theory of time. V x A = 1000kW. No rpm, no dynos, no amount of elapsed time. If you...

Oh dear. Put the car in top gear and went nowhere! Not.

Fastest accelerating production car in the world. Has one gear. I've said it already: you don't understand even basic physics. https://en.wikipedia.org/wiki/Rimac_Nevera

Oh dear. 400hp is available at all times, is it? Please explain this to us: How can an electric engine be rated at 1000kW regardless of RPM??? We all know 1kW = 1.34HP so how does that work? Explain. EDIT: It doesn't matter. We're just going around in circles now. There's nothing else I can...

And the Cummins could power the Duster. However the Cummins has a narrow torque curve and you would waste more time changing gears. If the Duster had an electric engine with a linear torque curve with no gears, it would go faster than both!

LOL! The difference is the weight.

Dude, you really are trying to confuse matters. It doesn't have to be this hard. Optimal gearing for an electric engine with a linear torque curve is what? Can a single piston two-stroke engine produce torque over one revolution? Yes Can a single piston four-stroke engine produce torque over...

Torque is a force. That force is provided through the transfer of energy. If we know what the potential transfer of energy is, we can know the force that will be applied. Potential force – just like voltage – can be measured without application. That means you can measure it without time...
