Customers generally look to superchargers for the instant throttle response, not fuel economy.
Superchargers are synonymous with making horsepower, especially in drag racing, gaining popularity and recognition as a viable power adder. However, they’re not the best option for saving fuel.
While most automakers are currently fascinated with employing turbochargers to make up for lost horsepower due to lower-displacement engines, do superchargers have a place in the current automotive climate? Indeed, this power-adder is more commonly found in the performance arena, because it produces power at lower rpm and comes in a smaller package than a turbocharger. But there are some downsides.
Variable-length intake runners change the length of the intake passages depending on engine speed and load.
Before removing the driveshaft, check for play in the yoke and slip joint. If the u-joints are failing, you should be able to see movement in the shaft as you apply leverage.
In the case of a direct fuel injector where the tip is exposed to the combustion event, carbon can stick to the nozzle and cause a bad spray pattern, because carbon searches for other carbon.

No matter the symptoms or damaged parts, the root cause of the failure must be diagnosed and resolved.
Known for their versatility and toughness, diesel engines are the first choice for many truck owners—and among those engines, Dodge®/Ram® Cummins® turbo diesels consistently rise to the top of the pack. Since 5.9L engines produced between 1991 and 2010 provide reliability you can count on, don’t trust their repairs to anything less than top-quality service
