We all want more power. Heck, even the OEs realize this as the torque wars are in full effect when it comes to trucks. However, many times, an increase in power results in failed emissions testing. If you have a 2007 through 2018 Cummins-powered Ram, your quest for emissions-friendly power has just been handled with a compound turbo upgrade by the folks at Diesel Power Source (DPS).
DPS is proud to announce the availability of an emissions-friendly, add a turbo kit for 6.7 Cummins. This is a compound turbo upgrade that utilizes the stock turbo and adds an S475 turbo (larger turbos are available). Adding a second turbo offers serious help with towing, lowering EGTs, and a serious boost in power — all while (according to DPS), being emissions-friendly. The DPS 6.7 Cummins twin turbo kit using the stock turbo works with or without factory emissions. The EGR, DPF, and exhaust brake can remain intact if desired.
The Diesel Power Source Add A Turbo Kit 6.7 Cummins Twin Turbo Using Stock Turbo includes everything for installation. This is a direct bolt-on compound turbo kit with no fabrication required and includes a two-piece 4-inch downpipe to clamp to the factory exhaust and a high-flow air filter.
DPS claims horsepower and torque are increased throughout the entire RPM band, and are significantly increased in the mid and upper range. Typical increases in horsepower of 22 to 26 percent are expected.
The twin-turbo kit using stock turbo is specifically designed for engines making up to 600 horsepower. If going beyond 600 horsepower, DPS recommends using the S480 turbo, which is good to 700 horsepower.
The Kit Includes:
- Air Filter
- Exclusive Cast Hot Pipe
- Support Bracket for S400 Turbo
