What do you get when you combine an electronics company with one that specializes in fuel injection and custom fabrication? In this case you get TS Performance and Scheid Diesel joining forces to bring us an industry first: a compound turbocharger system that utilizes a variable -geometry, high-pressure turbo. Designed for the common-rail 5.9L Cummins, it combines two heavy-duty, OE-quality turbos into one aftermarket application. With BorgWarner supplying its tried-and-true S400 and state-of-the-art VTG S300, TS Performance controlling the variable-geometry turbo, and Scheid designing and building the kit, the marketplace benefits from a well-crafted, dyno-proven, bolt-in system for ’03 to ’07 Dodge Rams.
On a recent trip to Scheid Diesel’s Terre Haute, Indiana, facility, we saw the fit and finish of this system firsthand as it was being installed on TS Performance’s ’06 Dodge Ram 2500. While there, we realized how beneficial the use of variable-geometry technology will be in the diesel aftermarket. Imagine driving the perfect truck: one that spools instantly, pulls great up top, and doesn’t smoke a lick. Whether it’s drag racing, daily driving, or towing, this type of compound turbo arrangement maximizes performance in all areas. Read on to see what the future of twin turbocharging may hold.

OE Concept, Adopted By The Aftermarket
The idea of combining a variable-geometry turbo and a large, fixed-geometry unit in a compound arrangement is nothing new. In fact, BorgWarner already brought this variable, two-stage turbo system (its V2S configuration) to the OE market for the 6.4L Power Stroke. For those who don’t know, the ’08 to ’10 6.4L Power Stroke engine benefited from instant spool-up and lower emissions from the factory, thanks to the V2S configuration. In the aftermarket, the 6.4L’s turbo arrangement, which was thought to be somewhat small in size (a 52mm variable-turbine-geometry unit combined with a 65mm low-pressure, fixed-geometry unit), could support more than 550 hp at the wheels.
A larger BorgWarner turbo from the S400SX line takes care of the low-pressure stage. The l
Although the same principle applies here, the difference with Scheid’s kit is it’s designed to maximize performance for trucks that have already been fitted with items like larger injector nozzles, stroked single or dual CP3 injection pumps, aftermarket fuel systems, and aggressive tuning. And the flexibility the variable-geometry turbo provides makes this system work in 400hp trucks as well as ones making 800 hp. Thanks to the efficiency of the VTG turbo coupled with EFILive tuning, anyone will be able to build a snappy-yet-smooth, smokeless-but-powerful truck that can still tow anything or perform at the dragstrip.
