I'm tired of the stock plastic ATI vlv. I have a P1 @ 9.5psi. Now I know that the ATI Race is overkill for my application, but that it'll work fine regardless. I honestly just want more sound! That being said, my car is a DD and I've heard that the ATI Race is quite loud. I would just like to hear how loud it actually is I only found one vid on here and it was poor quality and couldn't really hear much. Thanks for any help.

i believe that there is a metal bypass valve in the newer kits that sounds better/ louder for cheaper and might be easier to install

My kit is about 2yrs old. Newer than that? Because mine has a black metal vlv in it already that came with the kit. Also, I'm really looking for that WOW factor. That's my main reason for considering the ATI Race vlv. I just really want to hear/see some videos of it so I can try to decide if it'll be liveable for me, the driver, on a daily basis. She is my DD.

V-Series Tech on here has the race bypass on his P1 setup....it is sick.
Not sure if he has any good sound clips...actually, he's supposed to be posting some videos of him racing this weekend....

Either way, let me assure you..the sound is sweet. Whistles at part throttle, and whooshes like mad when you slam the throttle shut. Do it.

See, this is obviously what I want to hear. BUT, this is going on my daily driver. And I DO take the family in it sometimes on the weekends and once in a while up to South Carolina (2hr drive) to see family. My only concern is it being "overwhelming" when trying to carry on a normal conversation when at a stop light, cruising in town, or driving on the interstate. I'm fine with OTHERS saying "WTF IS THAT SOUND!!". That's what I want I just don't want to be saying that too followed by "Jesus, that's driving me nuts!", haha.

Here is a video clip of my car when when it was just about completed.

HELL NO! I guess im getting old, but the F1 im getting will make all of the noise I can handle. I think thats great for a wow factor when you pull into a car show or something, but you would get real tired of it in your dayly driver. my minds made up, recirculated mondo

Actually inside the car it's not bad at all. You would be surprised.

Well, I ordered it up today (atmosphere vent) from Bob at EPP. Will go on next week. What I'm going to do just to be safe, is CAP OFF the original bypass vlv flange. That way, IF the Race is too much I can just cap IT off and put the original bypass back on. I'm extremely anxious to see how it's going to sound. That vid you posted sounded SICK when you revved it up. I'm at work and our comps have only the tower speaker so I could hardly hear anything other than that. I'll need to listen to it when I get home to hear it at idle. This is the pipe mine will be going on...

Is that how they commonly sound when you rev them up??? If so, that's SICK. That's the "blow off" sound I'm looking for!! I'm sure it'll be diff. some though since I'm only at 9.5psi as opposed to 22!!!

Are you calling my car a lady? Actually my car was given a male personality when I bought it in 1995.

well I just got one too, after talking to procharger and some other experts in the buisness they advised me that if I did not have a valve that could move enough CFM I could actually damage the unit by pushing seals out of it. I guess if you hear any fluttering when you let off full throttle thats sending backpressue right to the blower and stopping the impeller or actually reversing its direction. so a little bit of noise is not worth damaging my 3000 new head unit.

I'm most likely going with this BPV ("Big red") as well. I would like to hear a few more sound clips though if someone would like to share. Thanks!

Put it on this afternoon. Turned out very nicely. And quite stealthy too...visually Believe it or not, it's NOT loud at all inside the car. As you can hear in the video though she def. makes herself known now. It's quite loud standing in front of the car. I love the way it sounds when "blowing-off" when shifting at/near redline. Shifting before redline or near it, you get some of the sound, but just not as pronounced. I'm wondering if the sound inside, or lack thereof, is due to the location of the valve? Or if it's just that it's on a setup that doesn't necessarily "need" it. Regardless, the horror stories of it being too noisy, at least in my case, are completely unfounded. It's damn near no louder than the the stock ati vlv. But the blow-off is SWEET I'm extremely happy I did this. She's gonna turn more heads now I can promise you that. I'd really like to get some vids while cruising and maybe some WOT driveby's. Those will come when I can get them. For now I have just one, which I'll put up here ASAP. Plus pics, pics, pics.......enjoy!
