Yes, I realize that air passes through the intercooler before it reaches your throttlebody/DV's, but are IAT's post intercooler lower then intake temps from ambient air? They very well could be, I have never tested them, but I wouldn't think that they were. Also, I realize that if you want to play devil's advocate you can just say that you are going to compress it again anyway, but its always better to start with lower temps regardless.

Just cause the MAP sensor entitles you to run a BOV doesn't mean that it work as well as a stronger aftermarket DV, I am sure a whole new DV system will come out in time and not just the aftermarket Valve...........

Doesn't every factory FI car have to reroute that air for emissions?

The RS6 Race Cars use a Divert Valve. Why?

Honestly, I have no idea what an RS6 race car uses and why.

Listen, stop dicking around and put in the Forge units. Then go out and buy one of these for the extra sound. You'll have the best of both worlds, more hp and better sound.

Here is a idea of what I'm talking about, sounds AWESOME!



ELECTRONIC NA BLOW OFF SOUND GENERATOR
Once the accelerator is stepped off, the NA Blow Off Valve will generate a sound like a turbocharged vehicle's blow off valve. The sound from the NA Blow Off Valve can be adjusted to be the same as a turbo blow off valve. The NA Blow Off Valve sounds like a real blow off valve in turbo applications. You will not be able to tell the difference on the sound generated between the NA Blow Off Valve & the turbo blow off valve. The sound generated is conspicuous, and will not make one have a second look to ensure if it is genuine.


how can you not buy the NA noise generator 2000 plus after that explination.

Lol


I ordered them then I canceled the order because I was like oh the stock units are good for 20-21 psi.

Then I a few weeks ago I realized how much i beat the shit out of my car and said to myself how much would that suck if my DV's gave out right now. And bam! good bye a couple days ago when I ran those AMG's.

Then today I had time to order them and I called and they were sold out. So a few weeks ago I got an offer to be sponsored by a BOV company and today I actually thought about it...

Hence the whole thread. lol

Lol ya but im trying to convince myself they are the same. hahah

Who knows maybe they are tho

Which BOV were you thinking of getting?


Nobody wanna listen to me when they install their BOV, it runs crappy because it leaks at the part where the intake temp sensor goes into the charge pipe. You have to find a rubber gasket to ghetto rig it in there, make sure all the couplings are super tight and the vacuum valve are on tight and you'll see what that does.

Might be placebo, but i notice turbo spools up faster, and in between shifts the car didn't lose boost like most say, car kept pulling...this is with an HKS kit btw

[HyperM3]

I will answer this because unlike others who just want to give opinions, I have had both on my car.

I had the UR Tial BOV for a while. I really liked it but in all honesty, you need to be pushing some good boost to get any sound out of it. I didnt feel any loss of power between it or the stock DV's.

About a month ago I switched to the Forge DV's. Immediately I noticed that boost was held better between shifts(on my car which is a manual, on an auto I doubt this would be an issue). I dont hear any woosh sounds any louder than stock. They make the engine bay just as pretty as the BOV in case you were wondering.

I would say go for the forge dv's if you could go for one in the first place.

what was wrong with how your sensor was fitting....what size of a gasket are you talking about did you rig??

All the hole that the temp sensor goes into, is made a bit bigger than stock, so slight boost escape from there. So you have to rig ur own gasket to keep the boost from leaking

sherwin my forge dv's just arrived today so if you wanna install em and maybe try em out (take a ride in my car afterwards? ) let me know when i can

[tek818]

you know my opinion already... dv's!

[luca335i]

Noticed no decrease in performance at all with my AA BOV, and the ladies love it.

I love AA BOV cuz u can only hear it when your at full throttle.

[Neema]

DV's

[sambonator]

Personally I don't think it makes much of a difference... BOV or DV... its not like DVs can create boost in the pre-turbo intake area anyway... if it did, it would get blown back out through the air filter to the atmosphere.

It probably does reduce vacuum a bit during shifts pre-turbo, but that's all, but at the cost of the air being hotter. Its going to be a lot hotter than the atmosphere...after all its the atmospheric temperature air that the intercooler uses to try and cool the intake charge.

I just installed the Forge DV and so far results have been outstanding! JB2H feels stronger and more linear now... but could just be the placebo effect.

I'm testing JB2HR with race gas later.

Sam, sorry if you have mentioned this in another thread but what spring did you go with?

I was running green, but I JUST installed yellow, to see if I feel a benefit. I haven't started the car yet with Yellow. I may go back to green later again if I don't see (feel rather) any benefit from it. I'll be testing again in a few

[Walked U]

Ya Im going to have to wait a couple weeks to get those forge DV's, they are going quick like hot cakes.

Yesterday I called up to see how many they had in stock and they had 3. Today I called to order and they were sold out, and I called super early PST.

every stock turbo car i'd seen diverts excess air back into the intake... are u saying no car should have a bov?

Are you talking about the sensor near the throttle body? If so, I don't think there would be any leaks because when I installed my AA BOV, there was a rubber O-ring around the sensor when fitting it into the aftermarket unit. I'm pretty sure it's a snug fit because before I put the screws on to hold it in place, the sensor didn't even touch the housing on the pipe due to the O-ring.

I don't know if that makes any sense to you, that's the best way that I know how to describe it..........

I never had an AA BOV so i couldn't tell you, but my kit was leaking right there because i can move the sensor in and out of that hole without any resistance so i knew it wasn't sitting snug...
