Horsepower, and torque are increased from 22% to 28% depending on your turbo selection.
All of our Compound Kits are excellent for towing. But for our best Towing Compounds Twins any of the kit using the 62mm compressor wheels, or the Stock Turbo.
Reasons Why Our 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.

Head Stud Recommendations:
- On 3rd Gen 5.9L trucks, head studs are highly recommended for boost pressure over 55 psi, and fire rings recommended for boost pressure over 65 psi.
- On 2nd Gen trucks and 6.7 L Trucks (3rd and 4th gen), head studs are highly recommended for boost pressure over 48 psi, and fire rings recommended for boost pressure over 55 psi.
- All or our Compound turbo systems is capable of well over 55 psi, but is adjustable depending on truck.
*Typically S300, ATS Aurora, Industrial Injection, or Garret PowerMax, HTT, or other turbos can be used in this kit.
**On the Stocker, or add-a-turbo kits a few modifications are used to make your stock turbo 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.
1-Year, Limited Warranty.
***On 2nd Gen trucks with automatic transmission. The trans oil heat exchanger on the side of the engine block may need to be removed or relocated, by using flexible hydraulic lines.
***Only 2002 and older kits come with a downpipe, 2003 and newer kits bolt right to the factory exhaust.
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.
"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....."
"Great choice for a aftermarket turbo, or even compounds! My DPS add on turbo kit is amazing, completely changed the truck, from egt, too spoil and psi. Completely recommend y'all!'
