The Banks 7-liter Supercharged Twin-Turbo Duramax is back in the Dyno Cell! Last summer, the engine was rolled out of the cell, torn down, and inspected. It makes its return to the dyno for a specific purpose: to tune our new AVL dyno itself. Since its installation in 2021, the AVL engine dyno has been calibrated using a stock, yet slightly de-tuned Duramax L5P. This allowed our engineers to calibrate the dyno at levels up to 350 horsepower accurately. However, to ensure the AVL equipment is dead accurate at higher levels, an engine is required that will produce over 1,000 horsepower for extended durations.
Automation plays a key role because perfect repeatability is mandatory. The engines must be taken through specific ranges and conditions for prolonged periods and repeated over and over for as many as 800 hours. Although the relatively new dyno has seen a variety of configurations of the L5P, none were powerful as the Super-Turbo. As such, the dyno needs to be calibrated (or “commissioned”) to read accurately. To do this, we must install a calibration arm on the dynamometer and the controls are set to zero torque, followed by placing a series of weights to the end of an armature. The torque value will be the length of the armature multiplied by the total weight. This value will be inputted into the dyno controller to ensure the load cell sensor output has not drifted. The point is to ensure the dyno can hold power accurately under all conditions; sweeps, low speed, high speed, and quick whacks of the throttle. Stay tuned for Gale’s upcoming video!
