Upgraded power is sometimes needed on a vehicle to ensure that it can easily do the job that is asked of it. Sometimes the upgrade power is also wanted by the driver to Improve the driving experience.
The best outcomes for power upgrades are those that give a valuable increase in power and torque and also that keep engine integrity and longevity. Improved fuel economy will often come with increased power. You do not need make your vehicle a ‘race machine’ just for the sake of power, But you should ensure that your vehicle performs the tasks asked of it with Air/Fuel Ratios, Boost and Smoke Emissions that can be sustained safely.
On any diesel turbo engine the process of making power involves a ratio of air and fuel with boost calling on the fuel delivery as the engine comes higher onto boost. Power increases require these ratios to be lifted and then continue to match the boost from the turbo.
The modern common rail is vastly different from the precombustion diesel engine and there are distinct differences in the methods of tuning for all of the types of fuel systems. Mechanical injector pumps are tuned by manually adjusting and occasionally adding parts, the electronic injector pumps require tuning boxes to enable any changes and the current common rail engines can either be tuned directly into the ECM or by a Tuning box (both have a place and can be set up to be safe for engine integrity).
You can also enhance the exhaust system, particularly if the vehicle tows or carries permanent weight. Changing the size of an exhaust can allow the turbo to spool up somewhat quicker. This does not in itself increase power, but will improve the driveability. In any case, the job of the exhaust system is to move the generated heat efficiently off the piston area of the engine.
Extend your engines life
Diesel Engines are not indestructible and it takes correct care and maintenance to keep these vehicles running. One way to maintain your vehicle is to monitor the excessive exhaust gas temperatures (EGT) that your engines emits.
EGT levels are especially important when towing or carrying loads as this can cause stress without any warning for the driver. An EGT monitor can alert the driver to dangerous conditions before damage occurs to the vehicle.
Why Install an EGT Monitor?
- Monitors Engine Stress when underload
- Keeps engine out of EGT trouble
- Acts as a guide to optimum fuel economy
- Reacts faster than the water temperature gauge
- Spots problems sooner.
Ensure your vehicle is able to warn you of dangerous conditions before the damage occurs.
