Adding turbo efficiency and environmental responsibility.
The Baja Bomber with its Cummins turbodiesel engine needs to breathe cool, pollutant-free air for optimal performance and reliability. Unfortunately, the dusty silt beds of Baja California, for which this rig is being tuned, provide little more than fine baby-powder dust, which quickly clogs most OE air filters. These bottomless beds of powder are also known for caking dirty grime to any exposed fluid or residue present under the vehicle. In this segment we will tackle these issues.
Everyone knows that increasing the amount of filtered air available to the engine can result in increased horsepower and torque. However, for a turbodiesel engine the benefits of such upgrades are increased because the turbo is compressing the air on its way to the intake manifold. This creates a vacuum effect at the filter element. So it makes sense that by increasing the surface area of the inlet filter, one can expect better turbo performance.
A larger inlet filter will result in quicker turbo spool-up and cooler intake-air temperatures. This is a good thing because less heat means the compressor wheel is compressing more air with each rotation. In effect, the difference in pressure from the negative side of the turbo to the positive side is decreased. That's called turbo efficiency, as it relates to the cold or precombustion side of the turbocharging process.
