I had the same question and was sooo confused with all the recirculating and what not. What you may be interested in is a splitter valve, it recirculates half and blows the other half off giving you that nice pssss sound it isn't as loud as the full bov but it's still nice I got one called a stealth splitter valve had no problems and it sounds nice! It also comes with an easy screw on/off adapter to change it to fully recirculating. 221258653406 paste that number into eBay brings it strait up you can also get forge alternatives for a few more squids. Hope this helps

For anyone that cares ive beem running a baileys dump valve on my agu for nearly a month now with no drop in fuel consumption no loss in throttle responce and no engine problems. Infact i think the forge was dumping red hot ait into my intake. If u have a agu running a dump valve will. only make noise not cause problems

Is you agu mapped? I ran forge split r on my mapped agu and i clearly felt slight boost loss due to it. Changed it to a 007p and was ace..when car was standard never noticed the boost loss. Yh it will not throw fault codes but its defo no where as good as a 007p  :wink:

no standard mines blowing off all the boost and i can say the cars just as quick and responsive. if you go for a drive then try and change your 007 it will be untouchable. it def pumps very hot air into the inlet but on a 150bhp car i dont think changing dv matters too much lol

maby on a highly modded golf a cold side relocation kit might be a better idea
