confines of the Mini N18 engine bay. Less space surrounding the factory diverter valve on
the N18 engine means the current Mini DV+ (Part T9352) cannot be used. Instead,
the T9353 kit splits the DV+ into two parts, the valve, and the solenoid, (which are joined
by hoses), meaning the solenoid can be mounted lower in the engine bay out of the way.
Other manufacturers’ products involve replacing the entire system with a traditional
pneumatic valve. (i.e. no electronic control).
This approach is really a step backwards in technology (a bit like replacing fuel injection
with a carburettor) resulting in slower response and effectively removing any control the
ECU has over the valve operation.
GFB’s DV+ solution on the other hand is more responsive,offers better boost recovery
on gearshift, retains ECU control and doesn’t cause compressor surge/ turbo flutter. Oh,
and it doesn’t require different springs or frequent rebuilds either.
