Bring the RPM up a little bit.

把RPM调高一点。

Try changing up at 5,000 RPM, not two.

等五千转的时候再换挡 别两千转就换。

Yep. At 3400 RPM. It can cut through steel like it was wubber.

对，3400转每分钟。它切钢就像切橡皮一样。

The engines spin at about 60,000 RPM, producing about 15 pounds of instantaneous thrust.

该引擎每分钟转动6万次，大约能够产生15磅的瞬间推力。

Finally, slow down to 40 rpms or less for about five minutes.

最后，将速度降到每分钟四十转或少于四十转，持续约五分钟。

Then increase your pace to 60 rpms and hold it steady for about 20 minutes.

然后逐渐增加到每分钟六十转，并以此速度持续踩二十分钟。

If you make the stroke of the crankshaft shorter, you're going to lose torque, but you'll be able to gain RPM.

如果你缩短曲轴的冲程，你就会失去扭矩，但你将能够获得RPM。

" You wouldn't believe the RPMs" – the revolutions per minute.

“您不会相信 RPM”——每分钟的转数。

Well, I agree with you, I have great sympathy for you, but we're dealing with airflow devices that go at 120,140,000 RPM.

我同意你的看法，我非常同情你，但我们正在处理以120 140 000 rpm 转速运行的气流设备。

120,000 rpm. That's equal to 30,000 g-forces.

120,000 转/分。这相当于 30, 000 个重力。
