The Detroit Tuned Bypass Valve

[180motorsports]

The Detroit Tuned Bypass Valve is a re-worked brand new OEM valve that is modified to eliminate the "Yo-Yo" in early year ('02-'04) Cooper S's, but is available for all year Cooper S's. This BPV uses a stiffer return spring, resulting in quicker boost generation, and thus quicker throttle response and transitions. The butterfly assembly is also adjusted to close fully, allowing for maximum boost. Perfect for the aggressive driver or racer. Expect a very minor loss in fuel economy, and a great improvement in throttle resolution and smoothness.

Every valve comes with full how-to instructions with great photos. Easy to install in about an hour.

I did the VGS mod, which does some similar things as the DT BPV. After living with the VGS for a while I've found I don't really like it and will be going back to stock soon. The DT BPV is probably a better solution than the VGS mod though.
