There's no hyperbole in saying that Cummins' B-series engine helped to redefine the diesel Motor lorry bazaar in America. An Aero Tonneau cover tapers down from the top of the truck's cab to the top of the tailgate, and essentially turns the bed into one massive fast-back roofline. As of 2011, true Aero Tonneaus don't exist for this application, so you will have to fabricate your own, but in doing so you'll end up with a truck that looks like no one else's.6.
Install a cold-air intake, high-flow air filter, aftermarket exhaust development, turbo down tube and underdrive pulleys. These upgrades are quite common, however they daily grind remarkably bright-eyed on diesel engines where fuel efficiency is concerned. Diesel fuel economy is directly connected to torque output with a apt size of fuel, so anything you can cook to embellish competence without injecting enhanced fuel is going to burgeoning fuel efficiency.
2. Buy and install an aftermarket power programmer with a fuel efficiency setting. A power tuner will probably make the biggest difference in fuel efficiency without tearing into the engine and making major changes to the hardware -- and even then, you'll probably never match the power tuner's return on the dollar.
3. Lower the truck. Your truck's aerodynamic size and aerodynamic profile has at least as much impact on fuel economy as its weight, which you can't very well reduce without scrapping things that you probably want. Lowering the truck will reduce its aerodynamic cross-section (the size of the hole that it must punch through the air) and the amount of air that goes underneath the chassis.
4. Install a front air dam that very nearly scrapes the ground, and cover the bottom of the truck with a flat, sheet-metal belly pan. A belly pan will smooth and accelerate airflow going under the truck, which will increase fuel economy and high speed stability. This is especially crucial for big 4WD trucks like the Ram, whose axles and transfer case make the chassis about as smooth as the moon.
5. Fabricate or pay someone to fabricate a fiberglass Aero Tonneau cover. Aero Tonneau covers are completely different animals from Flat Tonneau covers, which are merely flat sheets that cover the bed. The Cummins light-duty Motor lorry engine itself was an evolution of preceding designs, however the feature that Dodge opted to install it into consumer-grade pickups unreal it absolutely revolutionary. Dodge's Cummins diesel trucks aren't the most fuel-efficient vehicles in the sphere, on the other hand they cause suggestion efficiency in a differential confederation from any Gauze engine with the alike performance.
Instructions
1.Get rid of the dual tires and install a set of 20-inch rims no wider than eight inches, and go with a set of lower-profile, all-season Touring tires. A set of 205/60-R20 tires will work best for this application; they're only about 0.5 inch smaller in overall diameter, so your engine rpm will remain about the same. You'll rarely hear this from anyone with a clue, but big rims and skinny, low profile tires are dynamically perfect for this application. This package will greatly reduce rolling resistance over the stock 245/70-R17 (10-inch wide) tires, but will do so at a slight penalty to ride quality and traction.
