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?
