Why our Cummins Towing Compounds 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 works with its bypass ratio). Much cooler EGTs
  • It has more complete combustion in the cylinders because there’s more air in the cylinder to burn all of the fuel.

DPS Cummins Add a Turbo Kit 5.9 Cummins is the best fitting towing compound kit you can buy for your 5.9 Cummins. With lightning fast spool-up and huge EGT reduction allows full throttle towing up hills without stress. You'll be amazed how well this kit makes your little stock turbo run.

EGT TEST RESULTS: The following test results were to test different single turbochargers against our towing twins. Each test consisted of a sustained 400hp dyno pull. The test truck was brought up to a 400hp on the dyno, and then loaded to hold a sustained loaded pull, equal to pulling a trailer up a grade using 400 hp. The EGT's were read pre-turbo. The results follow:

  • Test 1 Stock Turbo: Max EGT's reached 1700 degrees, (Test Time: 13 seconds, operator ended test due to excessive EGT's).
  • Test 2 Competitors Stainless Steel Housing Turbo: Max EGT's reached 1700 deg (Test Time: 17 seconds, operator ended test due to excessive EGT's).
  • Test 3 Diesel Power Source Twin Turbos: Max EGT's reached 1290 (Test Time: 1 minute, EGT's did not ever exceed 1290 degrees).

**Exhaust manifold is CARB Exempt, and EO numbered.

** The standard kit includes an S475.

** On 3rd Gen trucks, head studs are highly recommended for boost pressure over 55 psi, and fire rings recommended for boost pressure over 65 psi. This system is capable of well over 55 psi, but is adjustable depending on truck.

***There are a few modifications we have you make to your stock turbo to work with this kit, the modifications will still allow the stock turbo to be used as a stock turbo if you decide to in the future.

    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!

    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

    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.
