Do you want to get the most out of your diesel truck? As most diesel owners know, there are plenty of upgrades available. We will go over the ones that we feel are the most important and most effective when it comes to modification
1) Turbo / Superchargers
Turbochargers are one of the most popular ways to increases the power of an engine. A turbo works by forcing extra air into the engine. Inside the turbocharger, a turbine is force fed exhaust gases which are then pushed through a compressor and then expelled out through the intercooler. Turbos from the factory are designed to increase air flow 3 to 4 times more than a naturally aspirated engine, where as an aftermarket turbo can increase air flow 5 to 10 times more. Aftermarket turbos will keep exhaust gas temperature down which maximizes engine performance. The air pressure created by turbos is known as “boost” and measured in pounds per sq inch.
Unlike turbochargers, which use exhaust gas, a supercharger is driven by the engine belt (or chain) and uses the crankshaft for its energy source. The advantage of a Supercharger is there is no lag, it supplies constant boost even at lower engine RPMs. Superchargers aren’t very common for diesel engines since they already run at lower RPMs than gas engines, but superchargers can add about 40-45% more horsepower to an engine and, like turbos, work best at higher altitudes.
The exhaust system in your engine is designed to reduce engine heat and release post combustion gasses. Upgrading the exhaust system will improve the overall performance of your diesel in a big way. Your engine will run much smoother, which means increased horsepower and torque. Most exhaust system upgrades will give you that aggressive sound you’ve been looking for too. Upgrading your exhaust system is also good to start with because it’s an easy installation. Most can be bolted to your truck with common hand tools.
3) Air Intake
If you want to seriously upgrade your truck and change this, you should definitely consider installing a cold air intake kit. Compression in a diesel engine cannot happen without the combination of fuel and air. The factory intake typically impedes air flow by having a restricted opening. This opening contains a sound “baffle” to limit engine noise. Removal of this baffle allows more air to be sucked into the combustion chamber and mix with the fuel. In addition to the baffle most stock air intakes have a paper filter. These are typically poor quality and get clogged easily. Aftermarket intakes use synthetic fibers that allow for greater airflow even when dirty.
Also, factory air intakes usually don’t draw cold air in from the most optimal places. Most likely, the air is coming from the radiator wall or from under the front fender. An aftermarket air intake will draw cold air that is outside of the engine housing. This colder air is much denser and contains more oxygen (the more oxygen in the air intake, the more that can be burned during compression). Upgrading the air intake, you can expect 20-30% increase in power and improved fuel economy.
