Only Yesterday is the proud owner of a "Dyno Dynamics" chassis Dyno. This machine was specially constructed for us with specifications far above most other chassis Dyno's. Our Dyno can road test rear-wheel drive cars up to 2500 horsepower and consequently we have had everything from a toy truck with 8 horsepower to Formula One race cars making nearly 1500.

Our Dyno is a very valuable tool to help us get any car to perform to its optimal specifications to provide maximum performance, low emissions, and the best fuel economy possible. Our Dyno operator was hired specifically for his expertise in using this machine. Once he was hired, we built our machine and its enclosure around him. Car clubs and high performance vehicle dealers have all used our Dyno and raved about its results.

Enjoy a 2 minute Quicktime Video of a customers' 1966 Chevelle on the Dyno, doing a variety of pulls. The numbers are reading a little over 400 horses at the pavement; on the graph, visible in the video. All the data is recorded for later analysis, and documentation. Shot in HD.
