Why DPS Cummins Twin 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 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 is cooler).
  • It has more complete combustion in the cylinders because there’s more air in the cylinder to burn all of the fuel.

Head Studs Recommended For Cummins 475 Twin Turbo Setups:

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
Our Compound Turbo systems are all capable of over more than 55 psi, but are adjustable depending on truck.

    I had the compound kit on my 5.9 Cummins for 4 years now. It made a huge difference in towing trailers. It spools up quick for when I need to get the camper or the trailer moving from a stop. Also, it does not take a lot of effort to make a pass on someone when I'm in a hurry. I would recommend this kit to anyone, whether they want to play or work.

  • Hello, I 5

    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.

    Best thing I could have done sooner was do compounds for my 6.7Cummins! Stock fuel with some items not on the truck and it tows awesome. Steep grades and EGTs issues are a thing of the past! Great kit

    I put one of these kits on my 04 Cummins probably 5 or 6 years ago. I have nothing but good to say about it. It has towed loads that do not belong behind a pickup, on a regular basis and has never once disappointed.....
