Reasons Why Our Compound Turbo Setups Work So Well

• More cool air goes into the cylinders because the dual-staged compressors work together in their best zones. The boost air is typically over 100 deg. cooler per pressure made than from a single turbo.
• The air entering the cylinder is at higher pressure. This causes the boost pressure and exhaust drive pressures to become nearly equal. The intake stroke can actually produce power.
• Extra air molecules in the cylinder don't carry heat out of the cylinder. They carry heat away from the cylinder, like a jet engine's bypass ratio cools the jets.
• It has more complete combustion in the cylinders because there’s more air in the cylinder to burn all the fuel.
• Diesel Power Source makes turbo kits for 5.9 Cummins engines using CAD/CAM Software, and CFD (Computational Fluid Dynamics) Testing. Our Cummins compound turbos give a factory-like fit with the highest performance possible. Everything fits like it was built from the factory, and it performs so well. You’ll wonder how you ever drove without them.
