Gray Engine Development has the personnel and equipment necessary to build, freshen, and update any type of internal combustion engine. From NHRA Drag Racing to the circle tracks of NASCAR and the World of Outlaws, contact the team at Gray Engine Development for all of your engine needs.

With controlled air conditions to the engine, the dyno testing process at Gray Motorsports is refined and as accurate as possible. Control of the air temperature, relative humidity, and also the barometric pressure supplied to the engine are just the beginning of the tuning process. From carburetors to fuel injection, our team has the experience to tune anything brought to our facility.

The Revolution Inertia Dyno was installed at Gray Engine Development in 2011. The unique features of this equipment allow for measurement of the natural engine acceleration rate against a known amount of inertia.

The team at Gray expanded their resources and capabilities when combustion analysis became part of the process in their engine building. Learning and applying combustion analysis has taken our team to the next level. Whether the system is integrated into our dyno testing process or used on the track, optimizing the performance of our engines is where we separate our program from the rest.
