I had the type H, sound was great, but my car just didn't like it. It was constantly wanted to stall out when i would rev and let go. I dont think this is a txs specific problem, i think its with all atmospheric bov's.

I have one and it works great with no problems. I want to sell it, but I love the sound and the head turns, priceless.

picked one up used for $140 from doogdog.

had 2 washers in originally. car idled fine, but throttle transitions were a tiny bit stumbly (for lack of a better word). most noticable at part throttle, right on the cusp of accelerating/decelerating.

inserted one more washer, and it was much improved. still vents fine... i hear the slightest bit of compressor surge during some transitions at very low throttle angles, every once in a great while, but i cannot replicate it, so it's not worrying me.

in all, my experience with drivability has been so close to stock that i see no need to switch back, other than the noise... and the noise is priceless. i find myself timing shift points to coincide with passing pedestrians on the streets.

what does compressor surge sound like? Is it caused mostly by the bov not venting when it should?

it sounds like a wuff wuff wuff, low frequency, almost like wind puffing. it occurs at throttle lift off and deceleration. it's somewhat similar to the wastegate sound, but the wastegate is more of a whistle (think old v-dub) pulsing in time with the exhaust, and occurs during throttle tip in and acceleration.

yes, it occurs when the compressor is trying to produce boost without enough airflow volume.

Had one, sold it.

I would rather not attract unnecessary attention to my car.

I literally had TWO instances where the men in blue mistook BOV noise for "tires squealing"

Dead serious.

One time I had to pop the hood and showed about 5 cops what it was and what it does, and why I have it (I lied and said it's more efficient, cause Im sure if I said it sounds cool they would have found a reason to give me a ticket.)

pros/cons:
1) it is Really F-ing Loud.
2) if you have a free flowing exhaust, get ready for fireballs

Wow... I've got to disagree with that.

Compressor surge is when your throttle closes but your BOV doesn't open enough to release that compressed air that's in your IC. The air then tries to go back out through your turbo, and it slows it down VERY suddently (About the same instant your butterfly closes). The sound does not repeat, it's a very quick "BARK!" as your compressor turbo screetches to a stop. Imagine the sound a turbine would make in this situation... that MFer could be spinning at up to 140000rpm.

As you can imagine, this isn't good for your turbo.

obviously you've never heard it first hand.

like anything else, surge comes in degrees. i assure you that i am hearing the faint precursor of a surge condition.

i may be stressing it, but only slightly..

Yep they don't call it [R]eally [F]fing [L]oud for nothing, it attracted everyone's attention, wanted and unwanted. I had it on and loved it at first, but it got old and ended up changing it after about 3 months. I too had issues with compressor surge at low rpms, but experimenting with the washers to find the best balance is a cinch..

Dude please throw that **** away. Those are garbage and will only kill your car. Unless you make it 50/50 or full recirc. But those things are a WASTE.

Before you post completely negative reviews with bogus claims, go read Unabomber's BOV thread. I bet every opinion you have about BOV's "killing" your car will be proven wrong.

Ya I've had one for well over 80k on my bugeye. Different turbos, tunes, and adjusting washers on it. 4 years, daily driven hard, dozens of auto-x's. Compression test was almost perfect last month. Noise is awesome and I love it. It sure is killing my car though.... pfft. Get one, tinker with it and enjoy.
