Why DPS Cummins Twin Turbo Setups Work So Well

  • 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 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 is cooler).
  • It has more complete combustion in the cylinders because there’s more air in the cylinder to burn all of the fuel.

 

Head Studs Recommended For Cummins 475 Twin Turbo Setups:

  • 1988-2002 engines over 48 psi boost, and fire rings for over 55 psi boost
  • 2003-2007 engines over 55 psi boost, and fire rings for over 65 psi boost
  • Our Compound Turbo systems are all capable of over more than 55 psi, but are adjustable depending on truck.
