The VAG Type 5 Smart Port Diverter Valve features innovative new drive-by-wire friendly staging technology. This eliminates compressor surge at both low throttle and high engine load while smoothly integrating with factory engine mapping. Plus a new hard-anodised, lightweight, aluminium piston provides better valve response and prolonged piston life.
The new Smart Port piston is made from aerospace alloy, reducing the weight of the piston, and improving the response of the valve.A new military-spec coating technique is applied to the surface of the piston. This low-friction material also helps make the BOV more responsive than any previous Type 5 BOV, plus has excellent wear resistant characteristics – extending the working life of the BOV.
Smart Trumpet Design
Turbosmart’s new Smart Port trumpet allows the use of a softer spring in the body of the BOV to aid in valve response to the plumb back port, while still retaining the ability to vent to atmosphere.
