From carburetors to fuel injection, our team has the experience to tune anything brought to our facility.
With some of the most experienced engine builders in the world, the refined techniques used to perform all processes of the engine build are found right here at Gray Engine Development.
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. Visit www.revolutiondyno.com for more information.
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.
