Why DPS Compound Turbo 1st Gen Cummins Setups Work So Well

• This 1st gen dodge cummins has a lot more cool air enters the cylinders, because the dual staged compressors work together within their most efficient zones.  The boost air is typically over 100 cooler per pressure made than from a single turbo.
• The air entering the cylinder is at higher pressure, bringing the boost pressure and exhaust drive pressures near or betterh thana 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 is cooler).
• More complete combustion in the cylinders because there’s more air in the cylinder to burn all of the fuel in the 1st gen dodge cummins.
