It's a metal vent to atmosphere blow off valve manufactured by Bailey Motorsports in the UK and sold here by Roadster Performance. It comes with a 1" silicone hose for installation.

The Bailey is great as it can be hooked up to the stock crossover very easily or attached to custom piping with no problems. I have mine on the stock crossover pipe for now. I attached it to the resonator box pipe. I used a 1.25" plumbing adapter to attach the BOV to the pipe. Works very well.

I'm very happy with the blow off valve. It doesn't leak at idle, it vents very quickly, helps keep the boost up between shifts and of course sounds cool =) It appears to be very well made and is of high quality. I bought the anodised blue version and it looks great in the engine bay. For $135 for the vent to atmosphere model it's a steal. Highly recommended!!!

Bailey BOV sold to be a replacment for the Mitsubishi valve that comes with the BEGI/FM kits. It can be used on any turbo setup though.

The valve was put together pretty well, except that one of the ports was loose and had to be screwed back on. The body is all metal (comes in colors or polished) and the piston is a type of plastic. The recirculating valve works very well and vents quickly and completely. It does make a noise that is commonly referred to as the "Darth Vader noise" since it sounds like Vader's breathing. The non-recirculating version of the valve vents very well, but flutters a lot. If you want a valve that vents to the atmosphere, there are better choices than the Bailey. If you are looking for a recirculating valve, the Bailey DV30 valve is a very good unit. It is also priced very well from Roadster Performance.

I decided to go with an all-metal valve (an AVO) since there have been failures of other valves that use plastic pistons and metal housings due the different expansions rates between the non-similar materials.

A high quality Blow off valve from England imported and sold through Roadster performance. I got the Recerc model, but they also sell the vent to the atmosphere unit as well.

I recently got the Bailey BOV from Roadster performance as a replacement for the low quality Mitzubishi unit that comes stock with the Bell turbo kits. I was very pleased at the quality of the unit right out of the box. It is polished aluminum body as compared with the plastic mitzu unit. I got the Recurc model since I wanted a direct replacement for the one that came in my turbo kit. The Bailey fits in the "near the turbo outlet " position better then the model it replaces since it is a bit shorter. The diameter of the inlet and outlet is 1' so I had to make a collar out of a bit of the high quaility reducer that it came with and used, the Bell hose over it where it goes into the intake. As of this writing Scott will have two reducers shipped with the valves, so you won't have to do this, but I have several hundred miles on the valve now and it has not leaked or blown off.

This BOV is very high quality, I tested it back to back with the mitzu unit it replaces with my mity-vac. I wanted to see how fast both opened and compare. The bailey started opening at 10inches of vacuum, and was fully open by 11, and then fully closed by 9. The Mitzu started opening around 14 was fully open by 18 and didn't fully close up until around 9. What this means is that the Bailey's about 3 times faster in response. Also the bailey doesn't leak at all at idle unlike the mitzu. I just chose to get the recurc model as a direct replacement. Which by the way it does superbly. It actually fits better in that spot then the one that comes with the kit. These valves have been tested on cars from 6psi to full race cars in excess of 40psi (they have been around awhile in the UK) I would highly recommend them, they don't leak, they hold the boost and they vent extremely fast! All the things that I would require a BOV to be. and they look great too. RumNHammer
