The dynamometer is a great tool for power evaluation but only if it’s used properly. Gale Banks reacts to a poorly executed dyno test of a RAM TRX. With nothing but a tiny shop fan perched six feet from the truck, the RAM's radiator and the intercooler have no hope of performing as they would on the road. Like many misinformed dyno technicians, the shop in this video has attempted to remedy the issue by opening the hood. Since you can't drive with the hood up, you shouldn't dyno it that way. #Am
