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. 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!


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

    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 $.

    Wow! A very noticeable difference in throttle response. I can really feel the difference at lower rpms, I now make full boost over the whole power curve. It pulls so much harder out of corners now.


  5. The Forever Valve 5 Star Review

    Posted by on 9th Nov 2015

    The stock valve in my '03 Cooper S was borked. Car ran like an asthmatic with pneumonia (I am an asthmatic and I had pneumonia more than once, so I know). It had no boost. The Detroit Tuned valve gave my MINI its lungs back. And I know it'll last practically forever with its reinforced spring and upgraded valve thingy. Awesome!

  7. Do you drive an 02-04 Mini Cooper S? 5 Star Review

    Posted by on 11th Aug 2015

    If so, this is a must have. I bought my 03 MCS about a month ago. I thought that it was a gas saving little turd. WRONG!!! I installed this Bypass Valve in about an hour, reset the ECU, and went for a drive. Holly smokes, my car hauls a$$ now. Must buy, must buy, must buy. Did I mention yet, must buy!


  8. Instantly noticeable improvement... 5 Star Review

    Posted by on 19th May 2015

    ... in both performance (acceleration response) and intake noise tone. Installed on my '02 R53 (w/ 107k) mainly because I had a budget for mods and wanted to address certain "common problems" /before/ they cropped up. To be honest, didn't believe it would make that much of a difference - I can admit I was so wrong.
    Highly recommended.
