Banks Power for Workhorse
At close to 500 cubic inches, the GM 8.1L Vortec in the Workhorse chassis is already the most powerful gasoline motorhome going. So how did the Banks engineers figure out how to get 22% more power out of it? That’s 66 more horsepower and 77 more lb.-ft. of torque. They did it the way we always do—by building prototypes and testing them exhaustively to see what really works best in the real world.
