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 Add the Ball Bearing option?
Improves spool-up approximately 150-200 RPM's.

- Balanced Exhaust to Boost Ratio
Reasons Why Our Compound Turbo Setups Work So Well
- More cool air goes into the cylinders because both compressors work together in their most efficient ratios. 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 has a full engineering staff, we make all compound kits 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.
Head Studs Recommended For:
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
2007.5-2018 6.7 engines, over 45 psi boost, and fire rings for over 55 psi boost
Our Compound Turbo systems can easily reach pressures of 55 psi or higher, and can be adjusted to suit different trucks.
