Mini Cooper Blow Off Valve Upgrade Gen2 R55-r61
$290.95 Mini Cooper Blow Off Valve Upgrade Gen2 R55-r61
Description

MINI Boost Bypass Valve Upgrade - recommended for the MINI Cooper S with increased boost, and for unmodified MINIs in warmer climates.

The factory engine uses a bypass valve to bleed off the excess boost during throttle transitions. The factory unit is made from composite plastic which can be fragile on modified engines or in warmer climate. The Boost Bypass Valve Upgrade is an upgraded bypass valve that is made from alloy and uses a piston instead of a diaphragm.

Fits the following Cooper S models:

2007-2013 R56 Mini Cooper S Hatchback
2008-2014 R55 Mini Cooper S Clubman
2009-2015 R57 Mini Cooper S Convertible
2012-2015 R58 Mini Cooper S Coupe
2012-2015 R59 Mini Cooper S Roadster
2011-2016 R60 Mini Cooper S Countryman
2013-2016 R61 Mini Cooper S Paceman

These products vary depending on the engine:

  • 2007-2010 Mini Cooper S models with N14 engine
  • 2011+ Mini Cooper S models with N18 engine

Model years are different for JCW models:

  • 2008-2012.5 JCW models with N14 engine
  • 2013+ JCW models with N18 engine

Make selection based on the engine in your Mini.

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. 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.

NOTE: Some states (like California) have ever tightening requirements for emissions testing and inspections. Always check your current state regulations on compliance for street use before you order.
