Stinger boosts performance, efficiency and engine life while adding hefty power at a modest cost. It also stretches your driving time between fill-ups! Banks stainless-steel Stinger energizes performance and adds substantial power gains at a modest cost. Stinger-enhanced efficiency prolongs engine life and delivers another +32 hp and +42 lb-ft torque to the rear-wheels, plus 5 percent more MPG. Important: Some vehicle configurations require an extension kit for proper fit - please see application notes below. Motorhome Power. Gasoline: Ford 6.8L (V-10), 1997-2002. Test vehicle: 1999 Fleetwood Pace Arrow Vision. Description: 35-foot with tag axle. Engine: 6.8L Triton V-10, rated at 275 hp. Transmission: 4R100. Rear axle ratio: 4.10. Horsepower and torque measured at rear wheels. Vehicle is EGR-equipped (1999 models only) if a large threaded fitting is present on top of second port of driver's side exhaust manifold. Class-C motorhome is Super-Duty (E-450) if catalytic converter inlet has slip connection. Class-C motorhome is E-350 if catalytic converter inlet has 3-bolt flange. Exhaust extension kit required for longer wheelbases. Measure wheelbase length from center front wheel to center drive wheel. Although the 6.8L V-10 Triton has two more cylinders than Ford's discontinued 7.5L V-8, its nominally 10 percent smaller capacity makes optimal engine efficiency critical to power production. If there's one thing Banks engineers know, it's that engine airflow is the key to efficiency and power. Banks stainless-steel Stinger unleashes impressive power, improves engine efficiency and durability, and increases fuel efficiency - all at a modest cost.
