4464 was put onto the load box this week to do the final tuning and rack settings on the engine.
Our friends from Drivetrain were present to perform the testing along with our old mate Col Parry.
4464 was hooked up to a portable load bank and when run at full power was making 1800 horsepower.
4464 will soon be performing mainline trials. We expect to announce the first tour soon.
