The Turbosmart TS-0304-1005 Type 5 Supersonic Blow Off Valve Kit helps protect the turbocharger on your higher performance diesel truck. The Turbmart BOV controller is an electronic device which 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. 

Diesel engines 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. 

The mid level type 5 blow off valve is suitable for moderately modified turbo diesels. 

Kit Includes: BOV Controller, Type 5 Supersonic BOV, Wiring loom, Solenoid and bracket, Reinforced pressure tubing, Hose clamps and mounting hardware. Welding and/or fabrication required for installation. 

  • Great For Moderate Turbo Diesel Engines 
  • 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.
