Yes you can!!! Keep reading...............

The following pages will show you how to build your own dyno, which will give you excellent results in accuracy, repeatability and economy. Unfortunately this is not a $100 project, however depending on how many of the pieces you have around and the resources you and your friends can come up with, you should be able to keep the total cost under $1500. Granted this is not an insignificant amount of money, but if done properly you will have a dyno that will give you the same and many times better results than commercially available units costing $4000+. Make it a club project, get a bunch of your friends together build it up and share it, you may even be able to make some money. Take a look, your questions and comments are welcome.
(This dyno was intended for Go-Kart racing engines, however it can be adapted to almost any application)
