Is More Flow Better, Is The Smallest Intake Port That Flows The Most The Best
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.
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?
I think we all know that. Perhaps the next graph can better explain why torque is king.

| Drag Strip | High Torque / Low HP | Low Torque / High HP |
| 60-foot | 1.69 | 1.69 |
| 330 – foot | 4.87 | 4.90 |
| 660- foot – 1/8th mile e.t. | 7.48 | 7.51 |
| ¼ mile e.t. | 11.64 | 11.69 |
| ¼ mile mph | 118.7 | 118.3 |
