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.

  • Efficient Heat Management: Extra air molecules in the cylinder retain heat.
  • Exhaust Downpipe: 1989-2002 Trucks come with 4" exhaust downpipe.
  • 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.

    Hello,I do not normally comment on my truck part purchases, but I felt the quality of your kit was worth taking the time for. I recently purchased one of your stocker / S475 kits for my 06 ram. I have to say I am very impressed with the quality and packaging you guys do. This is my first compound turbo set up. I looked at many kits before purchasing yours. I looked at cheaper and more expensive. I had nearly talked myself into buying a cheaper kit. After receiving your kit I was immediately satisfied with spending the extra money on it. I opened the kit and was very impressed with the packaging alone. I thought to myself, if it performs half as well as it is packaged, I was going to be very happy. I had one issue after installation, but it turned out to be my fault for assuming. I assumed the tube from the output of the S475 to the input of my stock turbo was molded to the connector that uses V band clamp onto the S475. I had one extra clamp once installed and I thought it was odd, however I took the truck for a test ride and was very impressed with the faster spool up but the system got very loud and not as much boost as I had anticipated. I found out very quickly where the extra clamp went. After that mistake was remedied, the system is performing flawlessly. I am very satisfied with this kit. I look forward to putting it to the test towing in the Colorado mountains. I will be purchasing your intake for this same truck as well as probably upgrading my stock turbo to one of your new ball bearing turbos in the near future. I will not hesitate to recommend you guys to anyone who asks.
