Why DPS Compound Turbo Setups Work So Well:
Our turbo allows more cool air to enter 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 or betterh than 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).
More complete combustion in the cylinders because there’s more air in the cylinder to burn all of the fuel in your Cummins truck.

  • Huge S471 Improvement! 5

    Posted by brodlr96 on Nov 13, 2023

    I purchased a 2003 Dodge 5.9 with a Borg Warner S471 turbo. It hit hard when I was at almost 3000 RPM but sucked to drive. I got the mechanical Turbonator vgt. I expected about 300-400 rpm better spool, but I swear it's more like 1000 rpm improvement. The truck is actually drivable and I can tow with it. It would not tow befor the VGt. a big improvement for big turbos for sure!

  • VGT Rocks 5

    The turbonator made my 12V come to life. Before and after difference on my 96 was night and day. noticible fuel savings and power gains, can't wait to see how she tows! BB was very helpful and fun to talk with.

  • DPS will not disappoint 5

    Beyond happy with the install and performance of my SXE366VGT from you guys. The performance is way beyond my expectations! Keep up the good work!

  • 5.9 Compounds 5

    Posted by Lance Dehne on Jun 19, 2023

    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

    Posted by Greg P on Mar 31, 2023

    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

    Hey fellas, did some upgrades after your compound set up. Hamilton stage 1 head, full manual valve body, 125 industrial injectors. Makes 683 hp and just under 1300tq at 7200 ft. Egts never get over 1100 no matter what I’m pulling or how I have my attitude adjusted. Tuned by grand by truck shop. This thing is a pulling beast. Thanks again.Â

  • I love this turbo!!! 5

    Posted by Edward Long on Apr 26, 2021

    I just installed the Turbonator VGT on my Ford 6.0 Powerstroke stage 3 kit. I already had an s300 turbo on the truck that wouldn't spool up worth crap. Since I put the DPS turbo on my truck I love this truck again! Hands down the best thing I've ever put on!
