I am new with audi's, recently brought a new b7 and saw that Forge have a new diverter valve for it, vag approved, i was wondering if anyone has one already installed and how loud is the sound.

with stock airbox i didn't hear a differance...install was pretty straight foward, i ended up breaking a nipple on a seneloid (oops) so the install took two days cause i had to wait for my dealer to get a replacement seneloid. But intall is very straight foward.

I just installed mine today, kinda hard with not enough hand space there, but, i'm not sure if it blowing rite, it seem to phssssssssssssp when i shift, but it makes phssssp, phssssp, sometime after i shift and speed up,it's like a vibration of sounds, is that normal? Thanks for the feed back.

i think i know what you mean...it's like as if the sound comes and goes but at a fast past right? if so that's normal

yeah i agree with space....it's deff not a easy spot for large hands

got mine installed this week (you guys are more patient than i). similar sounds coming from my stock airbox.

Let me know.

i just installed mine not impressed at the sound. you cant hear it in the car at all with the radio on low( has to be off)

i work for audi so when i was at work i tapped the holes so i could put screws in it and i tried the sound with one hole open ( sounded liek a sneeze) then i tried with 3 holes open ( was louder ) then i went and took all them out and it was loud when i was at a standstill buton the run it wasnt loud at all



so tomorrow at work im going to put back in the 3 screws and try it out!! hopefully it will be better if not im going to make a bigger hole and put a horn on it like a regular BOV and ill report back to you guys ( i also weld so i can weld the horn on)


then ill put a duck caller to it so when i shift it goes QUACK!

of coarse this is on a stock car with the APR 93 oct flash no air box or exhaust yet!

I just installed mine a few days back and I was impressed by the the sound of it... but the space I could agree with it too...

Where does the blow off valve go exactly? Does anyone have some instruction for the instllation of one?

Just curious, why install a BOV on nearly stock setup. Unless your running an agressive setup (e.g., larger turbo, high boost) there's no need to upgrade. This holds true in the Subaru world as well; I have a 06 STI making 376 whp @ 19.5 PSI (now a track car) I didn't upgrade the stock bypass valve until I went to a larger turbo.

I assume that this would hold true for the Audi tuning world which, I am new too.

In many instances after market BOVs release to much boost pressure on a stock or nearly stock setup and cause a loss in performance, possibly even causing stalling issues at idle or they may not open enough because, the springs are to stiff resulting in damaging compressor surge.

Personally, I will upgrade BOV until I hit the stock one's limits.

i am new too, got the 2007 a4 2.0T convertible 5 days ago, does anyone have like a DIY pictures of how to do that ??
