DIY Hub Dyno: Introduction [1]

[@ericmiller4285]

Very cool! I hope you continue to document this project. I too have been researching this exact same project myself. It would be "easy" to just simply order a Mainline hub dyno, but you know all too well its easily $100k for a base dyno shipped to the US... just not possible for myself to pay that kind of money to test and tune my vehicles as well as some friends...

You are a smart dude!

hi, I am build a couple of dynos a hub dyno 2wd with electronics from yourdyno and a small dyno hub for go kart and the roller dyno is true all you comments about of it for my is very dangerous the roller dyno deformation of tires and some times the car take direction for some side and the disaster

Super 👏

I don't know if anyone's mentioned this in prior comments (disclaimer, I haven't read though them), but if I were to build my own dyno, I would consult with someone like Steve Morris (who's openly shown his DIY dyno on his channel).. More over not so much for the principles involved, but for real world cost info on how much you might spend vs buying a turn-key type. Edit* provided you're open to a non-chassis based dyno.

Yeah I have worked through the cost a good bit in detail. Of course there are some unknowns, but not outside the realm of estimating. Some of the cheapest hub dyno systems I have found are still starting above 70k. I will be around 17k with this system. It helps I have machinist friends and work with engine dynos for a living. Steve Morris has some great videos.

@@carsandengineering2022 yeah after watching more of your video, I realized you're after an electrical breaking type dyno, where as Steve's is your typical water-brake (eddy) type dyno, while also more so specific to direct flywheel measured power.
