Product Description

The Detroit Tuned Bypass Valve is a re-worked new OEM valve that is modified by Detroit Tuned to eliminate the "Yo-Yo" in the MINI Cooper S's, the yo-yo was more prevalent for the early 2002-2004 cars but could happen in any of the years. What is the "Yo-Yo" effect? It's the opening and closing of the valve around 2500 rpm's so that it feels like your stepping on and off the gas, but you're not. So we added a stronger spring to overcome the vacuum condition that it sees so that it will not open as soon or as much.  Our BPV closes at 6" of vacuum, as opposed to the factory value of 0" of vacuum. MINI tired to fix the problem in the 2005-2006 cars with a ECU tweak but it never really worked correctly for a lot of cars. This was the main reason our BPV was created, but there are a lot of benefits, read on!

The DT BPV uses a stiffer return spring, resulting in quicker boost generation, and thus quicker throttle response and transitions. Most cars see about 1psi total more boost @ redline. The butterfly assembly is also adjusted as much as possible to close fully, allowing for maximum boost. This is done by centering of the butterfly door and adjustment of the set screw that sets the openness of the butterfly. Perfect for the aggressive driver or racer. It is possible to see a very minor loss in fuel economy, but you will see a great improvement in throttle resolution and smoothness.

Full how-to instructions (below) and all necessary hardware is included. Easy to install in about an hour. No core charge so there is no need to return your old valve. This part only fits the gen 1 2002-2006/7 Cooper S with the Tritech motor.

  1. Bypass valve 5 Star Review

    Posted by on 8th Dec 2017

    A must for any R53 running a reduced pully. My car feels more urgent and for a little more money than a stock one it's a no brainer! Also came with a free koozie and bottle opener, How cool is that!!!! I will definitely be making Detroit tuned my first go to for all my R53 needs.

    Posted by on 22nd Apr 2017

    Great service. Ordered this online and it was ready for pickup very quick for a Saturday! Got rid of the "yo yo" at part throttle. Only put a few miles on it but works good so far.

  7. Mini runs strong now 5 Star Review

    Posted by on 3rd Oct 2016

    Great product. At 110,000 miles it was time to upgrade. I was getting the dreaded 1237 code and power loss. Bolted up this bypass valve, erased the code and am happy to report the car is faster with no codes.
    Thank you


  8. By pass valve! 5 Star Review

    Posted by on 9th Sep 2016

    Nice product! Car seems much quicker on the throttle.


  9. Dang! 5 Star Review

    Posted by on 21st Jun 2016

    Well I knew the BPV on my 05 r52 was a tad weak, not bad but it took a bit to build boost so I figured I'd give the DT BPV a try and I'll tell you what, boost hits hard now! Right at 2.5k rpm I'm slammed in my seat and I stay there through the pull. It gives a awesome sound when letting off to shift too, like a nice clean "pop" of air pressure being released almost like a pseudo blow off valve but quite. Well worth your money, a must do mod for any r52/r53!


  10. works as advertised, how refreshing. 5 Star Review

    Posted by on 18th Mar 2016

    This BPV closes quicker than my stock BPV which means more boost down low which means bigger smiles. That makes it worth my time and $.
