Couldn't you just leave the recirculation hoses off of the Valve side and plug them?

Yes you could do it that way too. This way seemed safer to me. The only thing I was worried about was the plug being sucked into the charge pipe. Plugging the dv hose allows for the plug to fit tighter bc it stretches a little bit and also it would be nearly impossible for the plug to be sucked in bc it cannot fit all the way through the bung on the charge pipe.

Wow! Is this a joke??
This really looks like sh1t!!

What's wrong with just removing the hoses going from the DV's back to the intake and plug them?



And here's how it sounds on my car:

Correct me if I'm wrong, but did you really plug the pipe before the DV's??
In that case you do not have any DV's working any more!
NOT very healthy for your engine...

What's the purpose of this besides to make noises for other 18 year olds to take notice of?

Actually any person of any age that is not deaf or hard of hearing would notice it.

I can't imagine this mod doing anything other than creating a "whoosh" sound. If that's the case, then to each their own. I prefer to err on the side of caution when it comes to, what I consider, a very nice car.

Seems a strange thing to do to such an expensive car. I still have a HKS SSQV sat in my kitchen as I'm not sure I have the balls to fit it.

What do you think a BOV is? It's an atmospheric release of the pressurized air from the turbo. It's either go back in the intake, got into the atmosphere, or go back into the turbo. You are basically making a BOV.

I don't think there is anything unhealthy about it.

This mod can help you troubleshoot if one or more diverter valve is leaking.

So I think my DVs are leaking bad atm.. Should I remove the circulation ***** w/e and cover up the plugs? Let the DVs shoot into the atmosphere?

That's how mine is set up right now, venting to atmosphere and plugged intake *****.

I would like to know how to test or know if the stock diverters are leaking? I've been wondering if I have a leak or weak diaphragm.

What did you use to plug the the intake pipe? I would like to try this. I also think my DVD is leaking. It has some built up residue around it....

I did the same thing over the weekend, i went to our version of home depot, got some 25millimeter chair plugs and used this with a worm clamp . Then a pair of 25mm filters on my forge dv's....

the filters actually help to muffle the sound better in my honest opinion

Why filters on the DV side? I don't understand. Is it to help with oil being blown out?

Have no idea why anyone would put filters on the hose endings unless your car shoots a **** ton of blow by oil and sprays oil everytime you let off the throttle under the mildest conditions to WOT....And if that IS happening, you would DEF need to check your PCV valve/system since its not suppose to have really any oil in there in the first place.

IMHO this is something that can actually help keep your intercooler, intake manifold, chargepipe ect.. nice and clean since the small amounts of oil residue that most NORMAL N54 motors produce just slowly drip after it being built up onto the belly pan under the motor. I would much rather have it there than oil going into my intercooler or intake manifold when its not suppose to.

On the other hand, this should just be a temporary fix until you can afford a Tial BOV setup or HKS BOV setup ect.. Yes the stock diverter valves do the same thing a BOV does but wasn't designed for it nor was it designed to handle almost double the horsepower from the factory yet some people making over 500rwhp still have the stock DV setup and aren't complaining about them leaking ect....

Instead of putting filters on the endings of the piping, you should save the money and invest in a BMS OCC. By far best one on the market IMHO since its literally as simple as reading the directions on how to do it. Still, I would FIRST replace your PCV valve with a RB PCV valve which is way more durable under higher power outputs and hold up 10X better than the factory unit....Plus its extremely cheap...infact its cheaper than the stock ones lol...just checked really quick. You can order it from Rob directly, or go to burgertuning.com and Terry sells them for the same price on his site and they look to be in stock.

By the way, it is EXTREMELY easy to install/uninstall your PCV valve once you have your cowl and cabin air filter off so I def suggest you ordering one first, then the BMS OCC, and then a proper BOV setup to handle bigger power numbers than stock 8psi of boost that the car in stock form produces

sorry for the long response but just my 2cents on the subject. And a BOV sounds 10x better with the car being a manual 6-speed,******* ********* back exhaust (delete secondary cats=less backpressure) and your choice of muffler. I personally have tried just about every setup there is but nothing is better than 3"******* *********, secondary *** delete/resonator delete, to a BMW Performance exhaust! You can literally hear your turbos whistling which sounds so damn good
