Reasons Why Our Sequential Turbo Kits 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 much more efficient entering the cylinder than from a single turbo.
  • The air entering the cylinder is at higher pressure, bringing the exhaust to boost pressure at 1:1 ratio or better.  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 is more air in the cylinder to burn all of the fuel.

Diesel Power Source Sequential turbo kits are all designed on CAD/CAM Software, using CFD (Computational Fluid Dynamics) Testing.  Our Cummins Compound Turbo Piping kit give a factory-like fit with the highest performance possible.  Everything fits like it was built from the factory, and performs so well.  You’ll wonder how you ever drove without them.

  • 2003-2007 engines over 55 psi boost, and fire rings for over 65 psi boost
  • 2007.5-2018 6.7 engines, over 48 psi boost, and fire rings for over 55 psi boost 
  • Our Compound Turbo systems are all capable of over more than 55 psi, but are adjustable depending on truck.
