The Dodge Cummins diesel comes stock with great power and fuel economy and can be tweaked to get diesel fuel mileage in the upper twenties and some even report low thirties in mpg. That is phenomenal economy for a truck. They can also be turned into ground pounding monsters. Today we will take a look at a few of the modifications that can be done to make the vehicle either more economical or more powerful. First the most popular modification for any diesel is a performance chip. These come in chips, modules and programmers. All have the same basic functions although they will all alter the fueling in slightly different ways and have a variety of safety features. Generally for a conservative driver, with almost any diesel chip about three to four mpg increases can be achieved. Most of these chips add about 120 horse power on their top setting. There are some extreme chips though that will add about 230 hp and over 400 torque to the dodge Cummins diesel. Probably the second most popular modification for the Dodge Cummins Diesel is performance diesel fuel injectors. Upgraded injectors can also add economy for a conservative driver. The injectors come in stages that range from 50 hp to 150 hp over stock, and even more extreme injectors can be custom made. 50 hp injectors would be for someone looking for a little more power and better economy. 150 hp injectors would be considered extreme. They also come in complete injector replacements or just nozzle or injector tip upgrades. For any diesel that is being modified, a higher flow exhaust should be added to help it keep exhaust gas temperatures down and to relieve engine stress. Most people upgrade the size of the entire exhaust from the turbo. Others use the Aero Exhaust which is a muffler replacement only. The design of the Aero Exhaust increases the speed of the exhaust like a jet would as the exhaust flows through it. On the 2005 Dodge Cummins diesel the Aero Exhaust adds 19 hp and 38 dyno tested torque by just replacing the muffler. Another popular modification is the cold air intake which allows more air into the engine which helps to combust a higher percentage of the fuel. This gets more power to the wheels instead of out the tail pip in a big black cloud. http://www.articlearmies.com/articles/Autos/ford-diesel-performance.html Ford started it and the aftermarket finished it. The Ford Powerstroke Diesel comes from the factory with a lot of power, nice fuel economy and a serious towing capacity. Ford Diesel Performance has been tweaked a lot by the diesel aftermarket, and the Ford Powerstrokes can really be tuned up. We’ll talk today about a few of the common performance upgrades. The first upgrade that most people do to their ford diesel is the performance chip. Two of the most popular are the Diablosport Predator, and the Edge Juice with Attitude Monitor. These performance chips function in different ways. The Diablosport Predator is a hand held tuner that plugs into the diagnostic port under the dash, and it loads up a new program to the truck. The Diablosport predator has three power settings, on the top setting it delivers 120 hp and on the economy setting can deliver a twenty five percent increase in fuel efficiency to a conservative driver. The Edge Juice is a module that mounts under the hood and the Attitude Monitor is mounted on the dash. The Edge Juice with Attitude Monitor allows you to adjust the power as you drive which is nice when towing. On the top setting it also delivers 120 hp and on the economy setting gives about a twenty five percent increase in economy as well. The attitude monitor also acts as a full digital gauge set up and is used to monitor important engine parameters. These are some of the most popular Ford diesel performance chips. Another one of the most popular upgrades is the cold air intake. A Cold air intake is a large cone filter and is sealed away from the hot engine air. Cold air takes up less space and the more air you can get into the engine the higher the percentage of the fuel will get burned. This puts more power at the wheels and allows for better fuel economy. The other major modification that most people do to their Ford Diesel trucks is a larger diameter and less restrictive exhaust. A less restrictive exhaust is important especially when towing heavy loads. If exhaust gas temperatures climb to high, which can happen fast when towing, damage can be done to the engine. A larger diameter exhaust also relieves back pressure on the engine which allows for better fuel economy as well since the engine doesn’t have to push the exhaust away. The Ford Powerstroke diesel really is built Ford tough and there are many ways to make it even better.
