DIY - A3 Throttle Pipe

Sure there is, there just isn't anyone smart/brave enough to actually submit to a test. The cynics out there might assert these modders are afraid to be shown their mod doesn't do anything (other than quiet the little buzz box) but I've remained open to the possibilities. 'Still am.

Not even half of the physics of a pressurized contained filling and emptying has anything to do with volume. The size of any inlet/outlets and the pressure differences on either side are far greater factors. No one has even done a volumetric comparison to illustrate just how much smaller the A3 pipe is to fill than the GTI.

Call me an idiot if you like because I'm content so far with you A3-pipers just feeling good about getting your hands dirty for once. But until one of you starts backing up your claims, you're just as noisy as the stock noisemaker box. Who's the bigger idiot; the guy willing to ask for proof that something works or the lemmings paying twice as much for some part they read about on the Internet that "improves throttle response" with no actual proof?

"The pipe has to fill up..." Boost is a parallel process. We're not talking about serial events that lead to acceleration only one after another. Have you ever seen a boost gauge? Do you understand what it's indicating? I'll leave the ricer comment alone because if your answers are yes and (honestly) no, then we've got a conflict. Most kiddies get their boost gauge for show points and to impress their friends. You may have forgotten I was one of the loud voices naming the Forge spacer what it really is.

You're an idiot. There is no way to prove throttle response. It's been stated already that the pipe doesn't add hp/tq. So when you hit the throttle in your GTI, the pipe has to fill up, make that "cool noise" you ricers like, and then you go. Whereas, in a GTI without the pipe, you hit the throttle and you go....right by your car, but hey, you sound cooler. :laugh:

It should show up on a dyno as a quicker torque build up, when the turbo is waking up. But only if the dyno run is fast enough, if rollers have high resistance it probably wont show any difference.

I'm thinking any real difference will show up sharply on an accelerometer like a G-Tech or Escort G-Timer. You'd be looking for a dyno graph to move to the left, maybe, whereas an accelerometer would show shorter 0-60 times.

That is, if this pipe does anything. :poke:

a simple vagcom block logging of 115 would show something. to compare your boost curve before and after.

just dont get the pipe... theres nothing to it... if you dont believe peoples testimonials, then no pain. just dont get it. modding should be something you are confident with and if thats not the case then why try to get other people to convince you?

Scotaku, no one is scared of dyno'ing it. its rather a waste. we all know that it doesnt give hp/tq and we all know its a waste to dyno a before and after of a mod that has been confirmed to not give sustanial performance gains. its common sense. your argument wins here.

acceleration and response is best proved by math and if anyone is on here that knows how to compute physics, then be my guest. other then that, "throttle response" is just something that one of our senses pick up.

im not sure what you are trying to get from this arguement. to me, its virtually pointless. you know the answers but you keep asking them. leads me to believe that you are ignorant. please believe in yourself, there is no substitute for your own conscience.

What argument? I'm asking for someone to back up the repeat statements with some evidence other than what their ass has to say. If it works, then show me. Or quit saying it works. It's not whether I'll buy it or not because I've already said I'll buy it if it actually does.

And fwiw, I have a friggin G-Timer.

I for one won't stop saying that works, cause if I did then i'd be lying. If it didn't work then trust me, i'd say it didn't. I was skeptical myself, but I got the pipe for practically free, so I had nothing to lose. I was wrong about this pipe, and actually, I was impressed. I am a cynic when it comes to these simple mods, just see my posts on the vortex relating to the evoms 2.0t intake.

I don't have a dyno, won't take the time, and won't waste the money to do so. Why? Because you can FEEL the difference immediately upon driving the car. Thats all the proof I needed.

If you say it doesn't work, or it can't, then you prove that it doesn't.

If you don't want to put this $30 part on your car because it's pointless, then fine, don't do it. But the rest of us who have taken the time and the effort to try and test this part have noticed a difference. We don't need to prove anything. Most, if not all, of the people who have tried this mod have been satisfied that it made a difference.

It's like the "if everyone jumped of a bridge, would you do it too" thing. Except if everyone really was jumping off of a bridge though, then i'd want to know why, not simply assume that they were all crazy. They might be doing it for a reason.
My point is that many people are sharing thier opnions and they are being doubted, and criticized for not providing proof. My proof to you is that this many people aren't wrong when confronted with people who have not even put forth bthe effort to experience the duifference themselves.
Try it yourself, if you don't feel a difference, then come on here and demand proof. Just don't be dissappointed when I don't debate the facts to someone so close-minded.

If you want proof, then YOU need to find it. There is plenty of it here.

While this always seems like a good idea, there are just as many people who will argue that there are too many other influences and variables to prove the difference. In the end, we all have to prove it to ourselves, and no one else. It's just like dynos, most of them make matters worse, and not prove much of anything but all dynos, chips, and engines will give various results.

I won't offer proof, thats covered above.
I offer facts:

I'm 36, not some ricer fan boi.
I work for an Audi dealership, and have driven many A3's.
two of my best friends are Audi tech's who have owned/built modified VW's and Audis. They both currently drive A3's.
I didn't spend ANY money on the pipe to see if it would make a difference.
It took a whopping 20 minutes to do the swap.

I am telling you, straight out, this mod makes an immediate, and felt improvement to boost pressure build. Don't believe me, fine. I'm done here.

Someone wanna send me a boost pipe I'll test it. VAG - Dyno and all.


I'll dyno in stock mode w/EA, stock mode with A3 pipe, revo mode W/EA, revo mode with A3 pipe. The neuspeed intake would stay on through out the whole test though, unless i can find a factory box. Then I'll make all 4 tests with the box and then again with neuspeed intake.

So then we'll settle this debate? yes? Someones gotta send it to me though.... haha I'll pay for the dyno of course.

If you don't want to put this $30 part on your car because it's pointless,

If it was $30 everyone would. Come back to Sept 2006. This part is $60-$70 now. It was $34.95 when I bought it a long time ago.

It probably isn't worth the cost to do the mod. But it can be done without the pipe too.

You can pick up a $5 2" well/pipe plug(and other sizes) at a Marine/pool/hardware store, bolt it in, and acheive the same effect AND have it look factory for the dealership.


Where there is a will there is a way.

The only issue might be the turbulance having that Y and then a dead stop might cause...
