World’s First Lego Tachometer, Torque Gauge, and Horsepower Gauge that runs realistically

This video is about a fully functioning tachometer, with power and torque gauges that correspond to each other. I explain the torque and power curves relate to the RPM's. My gauges run as a typical gas engine would, where as the RPM is low, the torque spikes up. As the RPM increases, the horsepower gradually increases, and the torque decreases. This is the world's first fully functioning cluster of tachometer, torque, and power gauges. Thank you for watching.

Very amazing bit of machinery! It reminds me of the centrifugal governors on old steam engines.

Thank you!

really cool lego project! One thing to note is that Horsepower is simply torque * rpm / 5252. This means that the horsepower always equals torque at 5252 rpms, and the horsepower graph is simply dependent on the amount of torque made as well as the rpm; whenever the torque is constant, like your curve from 4k-7k rpm, the horsepower would be increasing. .

Thanks for the observation. I didn’t think of that. I was just trying to see if I can get the general motion of the gauges as I had seen in a bmw sport display. I’ll try to work this in if I do another one. Thank you!

Getting a torque curve out of this was awesome, you made yourself a great project!
