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

[@tylerwayne1693]

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!

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

Thank you!

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