The Turbosmart TS-0304-1001 & TS-0304-1002 Diesel Blow Off Valve System is an all-in-one kit for adding a Blow Off Valve (BOV) to protect the turbocharger on your high performance diesel. This kit includes the Turbosmart BOV controller, which is an electronic device that controls the pressure signal to the BOV. It works by detecting a negative voltage change in throttle position. It then energizes a solenoid to vent all of the air out of the BOV cap, causing a pressure differential between the piston of the BOV and the cap which will vent pressure from the intake system. 

Large diesel engines with larger turbochargers can experience compressor surge when coming off the throttle. The deceleration of the engine can be a restriction on the outlet of the turbocharger causing compressor surge. This can be disastrous on a turbo system which is producing high amounts of boost. The BOV controller can vent this build up of pressure, protecting the turbocharger. This can reduce the amount of rebuilds on your turbocharger as well as improve acceleration between gears. 

Kit includes: BOV Controller, Specific Race Port BOV, Wiring loom, Solenoid and bracket, Reinforced pressure tubing, Hose clamps and mounting hardware   

  • Includes Turbosmart BOV Controller
  • Vents Buildup Of Turbo Boost Pressure 
  • Electronically Controlled Through Turbosmart BOV Controller
Application Notes: 
Older models without a factory throttle position sensor such as the 12-valve Cummins, an external throttle position switch is required. This must be sourced and installed by the end user. This product requires welding, cutting and fabrication for installation.

Turbo smart blow off valve 2019 6.7 power stroke
(Massachusetts) | November 1st, 2020
Purchased the turbo smart blow off valve for my 2019 6.7 power stroke order number 1250534. I recently had one for my 2018 Ford raptor and loved it. The turbo smart 6.7 power stroke blow off valve is more practical then most upgrades as it can save you a very expensive turbo replacement. Installation is easy as it comes with an alloy well on flange. I personally needed the stainless steel flange for my stock hot side intercooler pipe that was stated it came with but was not in the package. After using a magic marker and the flange I marked out the locations where I needed the blow off valve NPT fitting to reside I drilled them out 2” and 7/8”perspectively and had a welder weld my Amazon 50 mm stainless steel flange and NPT bung to my hot side intercooler pipe. Looks and sounds great. XDP is a great resource for diesel products!
