Is whatever is on the turbo good enough. I'm sure some one might call me an idiot or something for asking but if I dont ask I wont know the answer.

If you have a stock turbo in your bugeye, then it is internally gated and is sufficient. However, you can upgrade your uppipe and go External Wastegate. This coupled with a nice aftermarket boost controller will give you some hp and tq gains along with better boost control. It will be very loud though if you don't plumb it back into your exhaust.

thanks, my car has a bad cat so I was going to order new headers w/up pipe and catless downpipe along with a tuner which I havent actually made up my mind about but was curious whether or not to mess with the wg.

Has anyone had any experience with the Turbosmart Dual Port BOVs? I know its a 50/50 but I just like the look of it and it sounds good as well. Just wondering if it is considered a "quality BOV" just because obviously the manufacturer talks like its the best thing since sliced bread, but I just want to know if any one knows whether they leak bad or are a **** product?

I have tuned dozens of cars with the Turbosmart. Its a good valve.

Thanks for the writeup!

Solved.

damick · 12-08-2010, 12:05 AM

what up yo'all! first time subie / wrx owner here..

after reading this 200 plus post thread, i have to say, my head is spinning.

all and all, i'm sold on the BOV, i got an HKS (which in did not get to fully exprience yet as my engine started knocking after just two days of me driving my very first subaru (wrx)

), but seems to me that BOV is not a such a bad thing. ( yes i did read throught he whole thread

)

I got mine purely for the sweet sound that it makes (although the descriptions of the products made me think that it actually makes the other parts of the engine last longer be releaving other parts of the pressure build up) which also seems to be one of the main reason they came up with the BOV idea according to that youtube video posted new posts earlier.

i'm sure I'll have to check back once i get me wrx running again..

I know Clark Tuner already answered your inquiry, but I can also vouch for the quality of this valve based SOLELY on my own experience. It's nice to hear someone with technical background confirm what I feel about this valve.

The valve is of sound quality, and when properly adjusted, never leaked for me. I fully intend on purchasing another one for use on my '11 REX. You won't be disappointed.

lillie18soriano · 12-31-2010, 04:31 PM

very helpful. <3

duffy94 · 01-01-2011, 01:37 PM

I just installed this in my legacy last night and the directions in it were for a wrx, also it didn't give me anything to block or shut the recirculating hose that puts the air back in to the system. will it hurt anthing to leave that open?

1. That valve is extremely obnoxious and you're gonna get made fun of for having it.

2. The car is not driveable until that hose is blocked.

duffy94 · 01-01-2011, 03:25 PM

Ok thanks for the help so how should i go about shuting this hose?

LGT/STi · 01-07-2011, 08:35 AM

Great post, good info

noonagon · 01-07-2011, 09:46 AM

I lo r my aps 50/50. Not sure if people.have been bashing or praising it yet but it keeps me.vented to intake on light everyday driving and vents when im on it hard. Not noisy or ricer

nighthawk06si · 01-10-2011, 04:30 PM

has anyone experienced or heard anything about the new cobb bypass valve?

Im picking up my first Subaru '11 wrx premium so new to the whole wrx scene and not sure what's good or not brand wise.

New02scooby · 01-10-2011, 08:15 PM

I have one on my '04 wrx and it works great. I have it set for full recirc. I'm also running 20psi of boost. You will be just wasting money buying any aftermarket BPV and installing it on a stock wrx. The stock BPV is great and should stay on your car unless it's broke. Don't go for the pppssssttt sound. You will damage your car.

Be creative, I once used a bottle cap that fit in the hose snugly, just make sure the clamp is tight...
