RhineWest utilizes a Clayton Eddy Current Chassis Dynamometer for general diagnostics and performance tuning. It's one a few variable load dynos in San Antonio, aside from those being used in the local research facilities. This dyno gives us an extraordinary degree of precision — up to 20 data samples per second as compared with some accelerometers that take just 10 data points during an entire test.
