DIRECT FIT FOR 2003-2007 TRUCKS

DPS turbos combine proven hardware with precision airflow engineering.

The S300 foundation provides a strong starting point, enhanced by forged milled compressor wheels, 360° thrust bearings, and oversized shafts for durability under sustained boost.

Where DPS separates itself is airflow design. They manufacture their own compressor and turbine housings, optimized using computational fluid dynamics.

This engineering approach reduces turbulence, improves flow velocity, and balances efficiency across the RPM range.

Benefits include:

• Faster boost onset
  • Lower exhaust drive pressure
  • Improved thermal control
  • Higher airflow ceiling

Performance isn’t just added. It’s engineered.

Sold standard with DPS wastegated exhaust housing.

• (Turbonator VGT Improves Spool-up by approximately 200-300 RPM’s. See below for details)

DPS Ball Bearing upgrades improve spool-up by 150-200 RPM’s.  Ball Bearing and VGT upgrades can be done together for massive improvements in spool-up and responsiveness.

Turbonator® VGT Exhaust Housing Upgrade

• Improves spool-up by 200-300 RPM’s.
• Allows exhaust braking on all truck years.
• Improves low-end power and torque.
• Improves low-end torque.
• Improves engine performance and output.
• More responsive and drivable.
• Cleans up smoke.
• Improves fuel mileage.
• Allows a larger turbo to be used because of the quick spool-up.
• Options are with or without exhaust braking.

Turbine Housing Info: Most DPS Turbos come standard with a T3 Wastegated exhaust housing, which can be upgraded to the Turbonator VGT/INT Housing.  DPS Wastegated housings flow approximately 22 lbs/min through the wastegate when it is open.  This is the equivalent of having one size larger turbine housing at wide open throttle, with the spool-up and drivability of a smaller exhaust housing when accelerating.  The best of both worlds!  On 5.9 Cummins engines their testing has shown their T3, wastegated, exhaust housings perform superior in all categories compared to T4 housings non-wastegated housings.  Their standard divided scroll turbine housings create boost nearly 100-200 RPM faster and flow equal to or superior to the standard T4 housings at WOT.  DPS also have their Turbonator® VGT housing available as an upgrade on most of their turbos, which improve spool-up another 200-300 RPM faster.

Why our Compressor Housings are better:

• Ported shroud inlet (unique design).
• More compact design for better fitment.
• Triple barbed inlet and outlet prevent tubes coming off.
• Up to 7% airflow increase over standard Borg Warner Housing.

DPS manufactures (designs, casts and machines) nearly all of their own compressor and exhaust housings.  Designed with CFD (Computational Fluid Dynamics) software for improved flow compared to anything their competitors have. Their engineer staff knows how their products flow and perform, They don’t just guess.
