Description

Full Mechanical BOV conversion for all V8 4 litre Biturbo M177 engines

Please note that this is NOT comparable to VTAs or adaptors that still use the factory valves.

This unit completely replaces the leak-prone factory ECU controlled valves with a purely mechanical valve that is only controlled by boost & manifold pressure. An essential upgrade for those with stage 2 and higher tunes where the factory valves can no longer support higher boost levels.


Specifications

Mechanical controlled Turbosmart VeePortPro styla Blow Off Valve, specifically made for ZAC.
Mechanically controlled ONLY from manifold pressure / vacuum. No annoying ECU control venting power.
Comes complete with valve simulation terminals, so your ECU still thinks it is doing its job. NO CEL!
Quality CNC'd from 6061 aluminum and anodized in BLACK.
Replaces both tiny stock electronic/ plastic BOV's with LARGE BOV in about 15 minutes.
Adjustable TurboSmart BOV tunable to your requirements by a simple turn.
Simply tees into factory manifold fitting with supplied tee.
Registered design. Copycats beware.
