DIY Dyno (Dynamometer): Part 4 - Proof of Concept

This is Part 4 of the Do It Yourself (DIY) dyno build. In this video, we discuss improving the sensors used for detecting the rpm, modifying the display for a more modern look, how to range the gauges for the signals that we measure then we'll do a power run and examine the output. See Part 3 - Software (link below) on setting up the Dyno parameters.
Correction: When looking at the output curve, the X axis should be RPM1 and not time. I was so busy trying to get it to work, I overlooked that dynos measure power and torque against rpm.

how would you make this large scale, i have various engine sensors and engine parts i could use < fly wheel < crank gears etc
i want to tune my car and street tuning is dangerous

The mechanics of it would be a big undertaking. You could use a big drum and lots of math. The biggest I've seen was one made for a motorcycle. czcams.com/video/XUX_YWsECWs/video.html
