A Word About Dyno Numbers
The Motorcycle Garage staff is often asked why we chose a Dynojet dynamometer over all others. Simple, it’s the most accurate platform for testing and EFI map building.
With a motto like “Tuned To Perfection”, it is very important that we be able to back up our claims regarding performance. It is also vitally important to be able to evaluate new designs in our development process. One of the tools we depend on for both of these functions is the chassis dynamometer.
Something that needs to be understood about dynamometers is that the results from one dyno will not necessarily be identical to those from another dyno. Comparing results from different dynos is bound to create a certain amount of confusion. This is especially true with dynos from different manufacturers. However, results of tests run on the same machine can be compared with a high degree of confidence. We can determine, for example if a performance modification increased power or torque, but there is a problem if you expect absolute values.
Motorcycle Garage has chosen to use the Dynojet dynamometer at our Phoenix facility because of the availability of data acquisition options that make these units well suited for development work. There are other brands of dynamometers which are in common use in the performance industry. These dynos will yield very reliable values for comparison, especially when tests are performed on the same machine. However values obtained from these dynos are typically a little higher than results obtained on a Dynojet. Which value is correct? It depends on who you ask.
On our literature and website, we publish dyno results so our customers easily can see how our products and tunes improve performance over stock. However, it must be remembered that these are comparative values, and should not be taken as absolutes. If a similar or even identical engine or motorcycle is tested on another dynamometer, the results will more than likely differ.
