Turbos will spool differently in every truck. Injector size, timing, camshaft, and other mods all affect the spool-up, the above table is the typical spool-up RPM's.

This Diesel Power Source compound turbo 5.9 cummins is perfectly engineered to offer remarkable driveability, while making a huge drop in EGT's, and large horsepower gains. Spool up is slightly slower than stock, but very reasonable on a modified truck. Whether BD, High Tech, Industrial Injection, ATS or other brand, these are all based on the same base turbo platform, with modifications. The compressor wheel flows approximately 1190 cfm.

This 5.9 cummins twin turbo kit is designed for a Dodge Cummins with larger injectors, chip/programmer, transmission mods.

Comes with a 1-year limited warranty. Easily bolts right on, we offer turbine housings in both 2nd and 3rd Gen sizes (4.0 inch and 4.4 inch), standard HX40 Style 4.0"v-band style outlet included.

12 & 24 valve engines, need a 4 inch exhaust downpipe.

Outperforms other S300 based turbos up to 66mm size.

*Turbonator ® VGT/VNT Option

3 Stage Mechanical Actuator VGT Included

  • Improves spool-up by 200-400 RPM's
  • Improves turbo performance and output
  • Hold the veins better at every position throughout the RPM range

Hybrid VGT Upgrade - Allow Exhaust Braking

  • Improves spool-up by 200-400 RPM's
  • Improves turbo performance and output
  • Adds Exhaust Brake to Turbo

Exhaust Braking Function with the Turbonator® VGT- will always increase exhaust pressure while braking, however, Diesel Power Source does NOT guarantee a specific Exhaust Braking force as every truck and application will be different. We mainly recommend the exhaust brake (hybrid) option for trucks built in 2003 or after.
