Why our Cummins Towing Compounds Work So Well

• The air entering the cylinders is cooler, because dual compressors work together within their most efficient zone. The boost air is typically over 100 cooler than from a single turbo.
• The air entering the cylinder is at higher pressure, bringing the boost pressure and exhaust drive pressures near a 1:1 ratio.
• The intake stroke can actually produce power.
• There are additional air molecules in the cylinder which do not get involved in combustion which carry the heat out of the cylinder (similar to how a jet engine works with its bypass ratio). Much cooler EGTs
• It has more complete combustion in the cylinders because there’s more air in the cylinder to burn all of the fuel.
