Hello Folks I just got a 2012 Mini Cooper S,
This is my first post so please don't shun me if I have posted in the wrong area.
I am looking into both the Forge Blow off valve, and the GFB DV+. Does anyone have any experience with both of these valves? To my understanding they both achieve the same end result but that the Forge BOV will give me more noise under the hood, while the DV+ is possibly a better engineered product but I won't get as much of the woosh noises. I do not want to deal with Limp Mode and a dash full of CEL's and that means if I decide to go the Forge route that I would be paying a lot more money for the full kit rather than just the valve itself. I sure wouldn't mind the woosh noises but the Forge system appears to be twice the price.
Could someone let me know if I am correct on any of this? I am mechanically inclined and just getting into cars as a hobby so I apologise in advance if my lingo is incorrect.
I have already installed the AEM 21-721C Cold Air Intake system on my own without any issues. I thought it would be louder in the cabin but I really don't notice any difference.
My plan is to install a blow off valve next, the the Burger Tuning JB+ then eventually a catback exhaust. I picked this order on purpose so that I have the diverter/bov installed before the JB+ so it doesn't stress my system too much.
Thanks in advance

I just st installed my GFB DV+ today and can say you don’t get any more noise but you do get boost that holds for a bit longer and I’m running 22lbs of boost and I don’t get any blowoff at light throttle. So far it helps with the issue I had. I also have the AEM Intake along with NM exhaust, front mount intercooler and 40mm turbo,

 

No we won't shun you, but we will move your thread to the right place. Welcome!

Plenty of threads here on the topic. On the N14 and N18 engines (you have the N18), the turbo has a recirculator valve - NOT a blow-off valve. The ECU expects that when the turbo has been providing boost and the throttle is closed, the diverter valve opens and the high pressure air is recirculated instead of being vented. So expect that if you put on a blow off valve, you'll get a CEL along with the whoosh noises. Some people say they don't get a CEL - some say they do. Research and read.

The GFB valve doesn't fit on the manual transmission R56S.

There's also an updated part for the stock diverter valve that doesn't have the failure problem of the original part and has been reported to hold much higher than stock boost without any problems.

 

Thanks folks. I will let you know what i decide to go with.
