BD Turbine Diverter Valve

  • Allows for a "Big Single Turbo" with less lag.
  • Quicker spoolup lowers EGT's & smoke levels
  • Increases launching boost!
  • Quicker 1/8 mile times
  • T3-T4 Option allows use of stock sized manifold
  • NOTE: This product CAN NOT ship to California due to CARB regulations.
Using larger turbochargers to increase horsepower results in slower spool-up response and could leave you lagging at the line. The new BD Track Master Turbine Diverter Valve will solve this problem by diverting all of the exhaust energy through one turbine volute (passage) which increases air velocity to the turbine wheel (the same principle as variable geometry), spooling it up like a smaller turbocharger and dramatically increasing low end power and torque.

As boost pressure increases and reaches a preset level, the valve will open the second volute to balance the drive pressures. Valve, flap and shaft assemblies are precision investment stainless steel casted, and, available in T4-T3 and T4-T4 mounting flange configurations.

Similar to the Holset Variable Nozzle, the Turbine Diverter Valve directs the exhaust gas into one volute which speeds up the turbocharger at lower engine rpm. Once optimum boost pressure has been reached, the valve will open up to direct flow through both volutes.

When tested on a 2006 Dodge with non-waste gated R850 primary turbo (Borg Warner S400 w/74.6 inducer and 1552 CFM), Smarty programmer at Level 1 and 120 hp injectors, dyno results showed an extra 130 hp and 330 lbs. ft. of torque!

With the Turbine Diverter Valve, your turbo will spool up quicker while reducing your 1/4 mile times, exhaust temperatures and smoke levels.
