Choosing Your Compounds is easy!
Determine your horsepower level at the wheels, keeping in mind our compound turbo kit will add about 25%.
If you have 400 HP, multiply 400 x 1.25 = 500 hp (this will be your power after the compounds).
Using this horsepower number, determine what Stage Level of kit you want from the list above.
Decide if you want to add the Turbonator® VGT exhaust housing option for faster spool-up and/or exhaust braking.
That's it! Select your kit from the drop-down.
Why add the VGT/INT option?
Improves spool-up approximately 200 RPM's.
Increases low end power and responsiveness.
Allow for exhaust braking within the turbo.

Why Diesel Power Source 3rd Gen Cummins Compound Turbos Work So Well
A lot more cool air enters the cylinders, because the staged dual staged compressors work together within their most efficient zones. The boost air is typically over 100 degrees 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 bypass cools the exhaust).
It has more complete combustion in the cylinders because there’s more air in the cylinder to burn all of the fuel, cleans exhaust.
DPS compounds for 5.9 Cummins trucks are all designed on CAD/CAM Software, using 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 performs so well. You’ll wonder how you ever lived without them.
