Fuel Economy was tested on the Mustang dyno using the OBD-II fuel flow rate and vehicle speed data, as well as the Banks emissions analyzer to measure fuel economy calculated from tailpipe emissions. The dyno was calibrated to simulate a 7,500 lb vehicle with an engine output of 30 HP required to maintain a 50 mph steady state speed. The truck was warmed to operating temperature then held at a constant 50 mph for a fixed length of time to procure an accurate average fuel consumption. The test was repeated for all covers as per their respective manufacturer’s fill level specifications.Features and BenefitsBanks cools 5X better than flat-back covers in on-road towing tests over the same road, same weather, operator and vehicleBanks cools 118% better than flat-back covers in controlled 200hp 60mph sustained dyno testsNew patented design features Ram-Air scoopsForces air up and into massive heat radiation fins providing the fastest cooling on the marketProvides cold high velocity air, overcoming “dead air zone” behind differentialEngineered to break-away if snagged on an obstacleInternal heat absorption fins transfer heat through the cover to the external finsDry-mount high-pressure silicone O-ring seal.
