Reasons Why Our 6.7 Compound Turbos Work So Well

  • The air entering the cylinders is cooler, because dual compressors work together within their most efficient zone. The boost air is typically over 100 cooler 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.

** 1-Year, Limited Warranty.

** This kit is capable of over 70 PSI, head studs are highly recommended for boost pressure over 45 psi, fire rings over 55 psi.

Free shipping to the lower 48 states. When shipping to anywhere outside of the lower 48 states, additional shipping fees may apply.

*Note: While the EGR and DPF can physically remain intact, most trucks will need to have already been emissions deleted. Diesel Power Source does not provide any emissions delete components.


They are towings best friend, I tow a 20 thousand pound trailer everyday and will never go back to a single, and boost psi is a more complicated question, mine go anywhere from 40 to 60 psi , but if you have stock fuel then 30 to 40 depending on truck. Justin Alamo

"My 09 6.7 with Diesel Power Sources add a turbo. This is my max egt on a 12 1/2 hour tow of 17k, pulling my camper from Gettysburg Pa to Nashville TN. It runs cool no matter the challenge!" Marcus Weeks

    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

    Great choice for an aftermarket turbo, or even compounds! My DPS add on turbo kit is amazing, completely changed the truck, from EGTs, to spool and psi. Completely recommend y'all!

  • Stocker 5

    I bought this add a turbo kit for my 2005 Cummins and what a difference it made towing. I live in the west and travel some good mountain passes with a travel trailer. No issues with the EGTs and no down shifting. I already want to replace my stock turbo for their Turbonator turbo. Great kit! and everything came in it to install.

  • Stocker Kit for Ram 5

    Posted by Greg Hillerby on Feb 19, 2020

    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.
