The SF-901 engine dynamometer was a workhorse in engine testing from the day it was released in 1982. Thousands of SF-901 engine dynos were produced and hundreds if not thousands are still in use today. The problem, the data acquisition system was designed in 1978 so it lacks features and capacity to adequately test modern engines and the majority of the electrical components required to service the data acquisition and control system are no longer available.
To help, we’ve developed a conversion kit to replace the dated SF-901 electronics with our WinDyn 3.2 data acquisition and control system. This upgrade allows SF-901 owners to keep the functional mechanical portion of their dynos and upgrade to the WinDyn data acquisition and control system making the dyno perform like new for less than half the cost.
