Roller Chassis Dyno VS Hub Dyno - Manipulating power and test variables

While at PRI Show 2019 we caught up with Todd Lewis to talk about Roller vs Hub dyno, and what variables can change the numbers when comparing between them. This also leads to talking about fudging numbers on dynos too, and how you can manipulate the dyno. The Mainline roller and hub dyno use essentially the same retarders and software, the only difference being the attachement to a hub or rollers, so can be compared "apples with apples". Todd has been designing, testing and building dynos for almost 20 years and has been involved with national elver dyno competitions, as well as installed and trained countless top level workshops.
