Banks engineers dramatically improved the V-10's airflow and optimized engine efficiency. Best gains: +53 hp and +69 lb-ft, and 7% more MPG. Although the 6.8L V-10 Triton has two more cylinders than Ford's discontinued 7.5L V-8, its nominally 10% 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. That expertise earned Banks the record for World's Fastest Motorhome: a PowerPacked Ford 6.8L V-10 Class-C Chinook that blasted past General Motor's record at 99.7 mph! Banks' stainless-steel PowerPack unleashes best gains of +53 hp, +69 lb-ft torque, and 7% more MPG. Important: Some vehicle configurations require an extension kit for proper fit. Motorhome Power. Gasoline: Ford 6.8L (V-10), '97-02. 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. 2004 and later Fleetwood-Powerplatform and National RV-Duraframe models - product does not fit. Note: excluding the 2004 and 2005 model E-350 van with an engine test group of either 4FMXT06.8TP5 or 5FMXT06.8RH4 and any truck equipped with a close coupled catalyst.
