Diesel Engine Performance Part Can Really Increase POWER!It is possible to add a simple diesel engine performance part and dramatically increase both horsepower and torque. On a gasoline powered vehicle, getting a comparable increase in HP and torque could take $1000's and $1000's, and a LOT of engine work (or more money to pay for the work to be done by a professional). Even if you spend BIG money, a street driven gasoline engine will rarely be able to experience an increase in power and torque comparable to a diesel. The diesel engine is different from it's gasoline burning relative in that more fuel equals more power. Up to a point that is... at some point you will get a black cloud from diesel performance parts that overfuel the engine excessively. In other words, a diesel engine will continue to make more power as you add more fuel, up until you add so much diesel that it is unable to burn it all during that combustion cycle. The partially burned fuel is what causes the black cloud of performance diesel trucks.
Blowing a Black Cloud at the Drag Strip Another big factor that limits how much fuel you can dump into a diesel engine is the Exhaust Gas Temperature (EGT). Adding more fuel raises combustion temperatures. Too much fuel can result in too much heat that can cause engine damage. This is quite different from a gasoline engine where adding extra fuel (richening the mixture) often lowers engine temperatures, and it is the excessively lean mixtures (not enough fuel) that can cause damage in a gas engine. Yes, both are 4 stroke internal combustion engines, but there are some unique properties of diesel engines that make it very easy to add a diesel engine performance part and substantially increase power on newer computer controlled diesel engines. It is possible to add a single diesel engine performance part and gain as much as +150HP and +300 ft-lbs of torque!! Often installation will just take a matter of minutes! Sounds too good to be true doesn't it?!?! What is this "magic" part that makes huge increases in power and performance?? Well, the diesel engine performance part is simply a computer chip or module that plugs into the computer engine management system of modern diesel engines. The chip or module tells the computer to inject more diesel fuel. Remember, on a diesel MORE FUEL = MORE POWER! Up to a point, of course. At some point, you can meltdown your engine from excessive EGT's and before that you will likely be blowing a black cloud of diesel performance overfueling. On gasoline engines, performance chips will often add only an insignificant amount of power that is hardly noticeable to the driver. Not so with the diesel engine!
Diesel Performance Chip In order to keep an eye on Exhaust Gas Temps, installing an EGT gauge (also known as: pyrometer) is highly recommended if you intend to install other diesel engine performance parts. What good would it do to get a short burst of unbelievable power, but destroy your engine in the process! A temperature sensor known as a thermocouple is installed in the exhaust system as close to the cylinder head as reasonably possible. This measures the temperature of the combustion gases and gives an indication of combustion temperatures in the cylinder. Typically, it is best to keep EGT temperatures under 1300F in order to be safe.
Exhaust Gas Temperature Gauge Another diesel engine performance part that is a popular upgrade for enthusiasts is the exhaust system. Don't expect the same sort of performance gains as you get with a good chip upgrade, but a larger diameter free flowing exhaust can help exhaust gases escape easier and lower EGTs. This in turn can allow more fuel to be safely burned. A performance exhaust can release additional horsepower and torque, but it's just not as noticeable on the seat-of-the-pants. On some systems, you'll notice it more with your ears with a more aggressive diesel rumble.
4" Diameter Performance Exhaust System There are many other diesel engine performance parts available like bigger turbochargers, twin turbo conversions, propane injection, nitrous oxide injection, larger intercoolers, free flow intakes. Aside from the intake systems, most of these upgrades are very expensive. So, if you are looking for the best bang for your buck in a diesel engine performance part, then you might want to consider a good performance chip. Don't forget the pyrometer to check EGT to make sure you are safe. And if you want to release a little more power potential, there are 4" and 5" diameter performance exhausts that help uncork some additional power and torque and help to lower EGT further. Also, remember a black cloud on diesel performance chips may be possible with more extreme calibrations that add a lot of extra fuel. For some people, this smoke might increase the fun factor, but you also might draw a lot of attention to yourself (some maybe from law enforcement!), so keep that in mind when choosing a diesel engine performance part. If you choose wisely, the increases in power and performance on a modern diesel engine can be AMAZING and for a relatively small price!
