Here are some suggestions and links to free plans and drawings for building your own low-cost do-it-yourself dynamometer frames, stands, dyno test-cells, etc.

      "These plans are made available on an as-is basis – without warranty!"

Before you begin, review some of these Tech-Talk articles below. They may help you decide what parts of your project you want to handle yourself. Note: many of the required specialty components: absorbers, data acquisition, deck plates, rolls, software, etc. may be purchased as separate components form Land & Sea.

*Note: These free, with the purchase of any of our data-acquisition systems, plans are not for the same designs as the DYNOmite models Land & Sea manufactures and sells. For example, they feature more simplistic construction methods and utilize more generic components (where practical) to allow for local fabrication.
