Catching Cheaters with Data

There’s much more information on a dyno sheet than just peak horsepower like catching cheaters. On this episode of Banks Entry Level, Erik Reider (Banks Special Projects Lead and Gale’s grandson) explains how a dynamometer works, how to make sure the collected data is accurate, and how to catch someone who’s faking their numbers. Everything you’ve ever wanted to know about the dyno sheet and how a dynamometer works is in this video!

13:49 Analyzing the dyno sheet
15:33 What is horsepower?
16:07 How horsepower is calculated
17:02 Catching a cheater

Erik also explains the importance of sweep time, the direct-drive gear ratio, and the source of RPM data collection for the run. We also discuss steady-state testing and its importance in developing components that can stand up to anything from daily driving to a grueling military operation.

Finally, Erik helps you put this newfound knowledge to work catching cheaters who decide to inflate their power gains by hiding data or taking creative liberties with the graph curve. Be sure to check out all the Banks Entry Level videos.
