Assembling a new chassis dynamometer 

why did you put second cylinder and not one for the measurment?

What is this flywheel off of? Do you have a parts list for this?

how many kilogram wight of roler?

What optical sensor for measuring the rotation did you use and where did you order it from? Also the disk with slots in it. Nice video. Thanks for sharing.

Donde conseguiste el rodillo y que medidas tiene

Hola que programa usa ??

chain lubrication ?

1:27 is that steel wheel welded together or purchased? I am looking for exactly the same thing to make my own dyno for a car. Low budget so can't afford a commercial one. Could you share some info? Thanks!
