Description
Forge Motorsport Atmospheric Dump Valve kit for the BMW Mini Countryman Cooper S 1.6 Turbo R60
FMDVR60A
This Blow off or Atmospheric Dump valve is for the Mini Countryman R60
that has the electronically controlled bypass valves (Cooper S models
). It is either recommended where the boost pressure has been increased
by an ECU software upgrade or simply for those wanting a loud Blow off
sound or simply as a solution to the many failures that have occurred.The
most common complaint on the OEM solenoid valve is a split diaphragm
preventing the valve from opening fully, or not at all. This doesn’t
always result in a check engine light as the valve can still be blown
open by the boost pressure. We have seen many valves with this problem
(see image below). The other problem is that diaphragm retaining ring is
made from very thin plastic that goes brittle with heat cycles, and
eventually fails. This prevents the diaphragm from sealing with the same
problems as mentioned above. This particular failure also results in
the valve falling apart upon removal from the turbo, though in extreme
cases bits of plastic can enter the turbo and destroy it. (see image
below). Our alternative is a fully engineered solution offering
both significantly improved reliability .Our valve is piston based ,
with no diaphragm to fail, and of all aluminium construction, it
replaces the original unit with a pressure/vacuum operated piston valve
that still also retains the desirable OEM ECU control over valve
actuation. The valve has been proved on the VAG scene for many years.
The spring is interchangeable for different levels of boost, and the
solenoid is plug and play with the wiring harness which is included.
