Reasons Why Our Compound Turbo Setups 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 typically over 100 deg. 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 ratio cools the jets.
  • It has more complete combustion in the cylinders because there’s more air in the cylinder to burn all of the fuel.

Diesel Power Source compound turbo 5.9 Cummins turbo kits 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 drove without them.

"Hello,

I don't 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's 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 it's 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.

Thank you,

Greg"

Not that Larry Bird.  Your Add A Turbo Kit for my 2012 made a huge improvement on towing with my truck.  Great power and helped with my EGT temps.  Once the stock turbo goes out I plan to upgrade with the Turbonator.  Thanks for making a great fitting kit
