Is More Flow Better, Is The Smallest Intake Port That Flows The Most The Best

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 change resulted in an extra 39hp. But was the car any faster? Can you tell by looking at these dyno figures which car is faster?

Trick question! They were almost identical because the average torque (and power) are almost identical.

Drag StripHigh Torque / Low HPLow Torque / High HP
60-foot1.691.69
330 – foot4.874.90
660- foot – 1/8th mile e.t.7.487.51
¼ mile e.t.11.6411.69
¼ mile mph118.7118.3

OK, so that 39hp was worth an extra 0.05 and 0.4mph. Now, which of these engines – considering they are just as fast as each other over the 1/4 – is really the better engine?

Who talking peaks only, yes it about the curves the hp curves.

Here's a tesla dyno chart, see why it don't need gears it makes enough power from zero to 127 mph and able to turn enough rpm's to do so. At 8 mph it's making 67 hp at 4 mph about half that more than enough power. If you wanted to go quicker you'd add a couple of gears to get in the 250-300 kw quicker between zero-55 mph.
