Unleash your Cummins true potential with the Turbonator® VGT  S300 & S400 Turbos.

Unmatched spool-up and turbo performance with the Turbonator® VGT—the ultimate upgrade for your Cummins Diesel pickup. Whether you're towing heavy loads or looking for a boost in mileage, power or responsiveness, our Turbonator® VGT Upgrades are engineered to maximize the performance of your diesel engine.

Turbonator® VGT for Dodge Cummins 5.9 & 6.7 Cummins is brand new patented & patent pending variable vane turbo technology, NOT a modified Holset vgt.

You have never seen this technology before!

On 6.7L Cummins Trucks, this is NOT a factory replacement.

What is the Turbonator®?:

The Diesel Power Source VGT / VNT are performance S300 & S400 Based Variable Geometry Turbochargers, the turbo vgt designed with aerospace-grade stator technology making it extremely robust and durable. The patented/and patent pending stator housing can be clocked independently to fit multiple applications. The ultra efficient stators on the Turbonator® improves spool up time by 200-400 rpms, lowers EGTs and improves fuel mileage. When our variable nozzle stators were CFD tested against sliding style VGT, like the Holset VGT's, the testing showed that our turbine housing is much more efficient at putting exhaust energy into the turbine, and flows much better overall.

On the low-end the DPS Turbonator® spools up quickly like a small turbo and on the top-end it the open stators allow maximum airflow and performs like a much larger turbo. The Turbonator will help you get that heavy load moving and keep it moving even when you hit a grade, while keeping EGT's in check. It will reduce low-end smoke, improving low end torque. It reduces smoke because it burns more of the fuel in the cylinder, translating to more power and better fuel mileage.

The Turbonator® comes in the pneumatic or electronic option. Unlike the Fleece Cheetah VGT, or the BD Screamer VGT, that are merely modified stock He300VG VGT turbos with the small stock housings and stock parts, our Turbonator is a completely new, from scratch, innovative VGT / VNT made for performance applications. It is unique enough to receive more than one patent. Because the Turbonator® is based on the S300 and S400 turbo platforms they flow much more air and exhaust, keeping down drive pressures, and allowing a greater than 1:1 exhaust drive to boost pressure ratio, which is virtually impossible with other turbos.

Turbos will spool differently in every truck. DPS S300 turbos for 5.9 & 6.7L Cummins are an excellent choice for the small charger in compound turbo applications.

  • 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!

  • 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!
