Note: These are true numbers measured on Dales in-house Dynojet 150 Dynamometer with the "Win Pep" program and then reformated for the web.

The Holeshot compound is about 200 feet above sea level and the dyno room stays at a constant temperature between 70-80° F. These results were also achieved with Dales tuning, which is a bonus. Dale uses his dyno as a measuring tool for development and testing only.

Be aware, that dynos, dyno operators, conditions and bikes can vary 3-8 hp, so this should only be used as a reference for before and after results.
