At Rossini Racing Engines we offer full dyno tuning service to all our Spec Miata and other engine customers, as well as to anyone who needs it, regardless of engine builder. And dyno tuning is possibly the least money that you will spend to get the best return on your racing dollar. The HP gained per dollar spent is normally higher than any other work you can do on your car.
Our portable DynoJet rolling chassis dynamometer is the industry standard in dyno’s and provides accurate real time measurement of the engine output and a host of variables that we use to tune your engine to maximum output. Out dyno has a full weather station so that we are able to tune specifically for the current weather conditions, or remove the weather conditions from the equation and give you results that will work at any track.
While some cars arrive at our dyno very close to optimum tune, it is not uncommon to find Spec Miata motors where just a few pulls on the dyno and a small amount of tuning will yield gains of more than 10HP and 10ftlbs of Torque. In fact at the recent Roebling National we had three nationally competitive cars which we were able to tune and yield an average gain of around +6HP and +6TQ. Gains like this on cars with only 120HP are significant and make the difference from running near the front or running mid pack.
While the car is on the dyno we are able to observe, set and optimize many parameters that affect engine performance
Remember that dyno tuning is both an art and a science. The data, the science, provided by the dyno computer is just the start. This information gives us black and white information that forms the basis of what we do next, and that is the art. A highly skilled and intuitive dyno tuner, in order to get the most of that engine, needs to add to the data a range of parameters that include
