Engines first go through a break-in process, then all valves are adjusted to cam manufacturer's specifications.

The oiling system we use is a remote Oberg Filter and HP6 Canister Filter. After break-in and during engine tuning, the Oberg is observed for any abnormal wear (metal, bearing material, etc.).

The Accusistion System consists of the Wyndyn software, air and fuel turbines and the Innovate lambda sensors.

Engines are tuned for maximum torque and horsepower output. Timing is adjusted and recorded, as well as carburetor jetting. Customer is allowed to view process, if wanted.

Our dyno room has been certified by Superflow and our staff have been trained and certified on-site.

All printouts are available upon request. Also, engine pulls can be burnt on a CD for customer to replay on computer.

All engines are leak down tested before removal form Dyno to assure complete break-in using a dual gauge leak down tester.
