Intake installed and having problems

[inked_up415]

I just had my AFE intake installed and have some issues with it. First, there's absolutely no turbo sound like what I'm used to hearing in my past Audi B5. It's certainly not the reason I purchased it, but it bothers me that the sound isn't there and has me scratching my head trying to figure out why. Next problem is that I think I actually lost some acceleration power. Does anyone have anything to say about this or have any ideas or advice? Lastly, was the air induction pipe supposed to be placed back on after? The pics I'm seeing online of other people's installs dont show it. Here's how it sits in the car now.

Take the intake scoop out and show another pic. Did you damage your maf at all?

Okay I'll remove the scoop and I don't think so

It was installed by a performance shop

Most aftermarket intakes lose power, so that's not a surprise. The sealed stock intake draws much cooler air and is not a limitation at all.

I can't speak as to why you hear less noise than on your B5, though. Maybe your B5 A4 was running higher boost pressure.

I'm pretty sure b5s just have louder turbo spools in general, my friends b5 all stock is louder than my b7 with an intake and exhaust

Hmmm well it was a stage 3 with K04 boosting at 18PSI. I just assumed it would sound kinda the same. The guy I bought the intake from has a B7 with stock turbo and his was loud. I don't hear anything from it at all.

Is your DV a stock one? If you have a DV+ that'll help enhance the sound

What are you basing this on? Numbers I have seen do not agree with this:

MOST WHEEL HP - best wheel HP reading out of the 3 runs
- Carbonio 177.4
- EIP 177.4
- AEM 175.4
- GHL 174.7
- K&N 170.6
- Stock 166.6

Clearly the stock isn't 'sufficient'.

Have you got any basis for your claim? No offence, I just like to confirm my understanding of things.

The numbers you posted are from a MK4 R32 with a naturally aspirated VR6 and could not possibly be any more irrelevant.

I will rephrase my post to say "many" intakes, specifically open element style units, can cause a decrease in power under certain conditions due to heat soak. Is that better? The only reason to purchase an aftermarket intake is for sound.

He's right. Especially an intake that don't have a full housing. If there is more heat soak (hot air being sucked into the intake) there will be less output. I know that APR Carbonio and ECS intakes do a great job of making the turbo spool and if you upgrade your diverter valve that'll help with the lack of power. It sounds like your DV probably has a crack in it which would make sense why you have a loss in power. That's an easy fix and most people would say you should upgrade the DV anyways because the stock ones are made horribly compared to the new ones.

Why do people do this when there is plenty of info letting you know it's a waste of time and money.

^ to each their own................

OP - I would def check your DV and upgrade it if you havent already, as pointed out above. Also take a look at you vacuum lines. One of them might be crimped etc from when the intake was installed.

[z_wrecker]

you can also remove some of that baffle material for more sound

That's an R32 MK4. Isn't it a non turbo V6? How can you even compare the two? It's a fact that CAIs don't provide gains for our cars.

I highly recommend researching setups specific for our vehicles prior to spanning out to other sources. Ive Solved a lot of issues finding stuff specific to the B7 that way.

Theres no point in spending over 100$ on a brand intake for the b7 a4. Carbonio and ecs are charging way 2 much for something that will give u what 2hp+? lol

Here is my opinion on best and affordable setups.

1. Only upgrade the drop in filter. Keep stock air box.

2. Delete the stock airbox, slap a good 6inch cone filter and install proper heatshield like the rare heat absorbing"blinktek" shield.

For best performance:

3. Get a FMiC, Delete your intake box. Route the intake inlet pipe down towards the passenger fog grille vent and sit the cone filter there. It will have direct cold air coming away from the engine.



Heres my 125$ intake setup. The blinktek replica really absorbs the heat from the engine/Cat so it doesn't transfer over to the cone filter. I still use the stock air scoop to direct outside cold air over the filter.

If you have a front mount intercooler you could move that cool air intake to where the side mount intercooler used to be giving you the the best possibility of outside air exposure.

yeah behind the fog grill lol. I still have my side mounts but once i go FMIC ill be rerouting my intake down there.

Drop in filter and call it a day FTW.

After driving around this weekend I've noticed a few things after the intake was installed on Thursday. The power loss is most noticeable when really applying throttle and can be felt around 4K RPM. Accelerating on the freeway I felt the car bog down almost and there was an inconsistent amount of acceleration. The car used to give a noticeable amount of pull when in the turbo band power range but now it feels like it's an NA car that's lacking any boost.

[inked_up415]

Such noticeable power loss seems unlikely coming from an aftermarket AFE intake. It seems like something else is going on here. But the likelihood that something broke or failed on the same day that the intake was installed seems like too much of a coincidence. I'm taking the car to my mechanic (not the intake installer) to see what he can make of this.

The claims above need to be backed up by data is all i am saying, there is a lot of people saying it isn't worth it, yet regardless the stock intake is a restriction.

You haven't seen rain until you have been here in the summer. Just sayin'

This very comment is true. we got about 11 inches in one day (that's what she said) last year..... My car had to stay home and I ubered to and from work.

[inked_up415]

Update-
After my mechanic looking at the car he concluded that it's sucking in too much air through the intake and causing power loss. How does that even make sense? I doubt he test drive it or ran an tests on the engine. If it is getting too much air and the engine isn't responding well then wouldn't it have something to do with the MAF? Is there any way to test it?

I grew up in the UK .. Rain is a constant .. and what else would you expect when you are on an island in the North Atlantic ..

Florida is in another level completely . With the water table about 4 inches under the ground and a rain fall that drops as much in 5 minutes as it can in the UK in a week , it isn't long before you are wading ankle deep just to cross the street. you would not want an intake anywhere near this.

[ECS Tuning-Audi]

I have the same intake on my car for the B6 and I have minimal turbo noise as well. My thoughts are that the plastic pipe dampens most of the turbo sounds, where as aluminum, rubber/silicone pipes do not.

Being the results are the same on two different turbo vehicles and both intake kits use plastic pipes leads me to believe that's the issue.

Theres a post on Audizine showing the restriction in air as measured with stock and aftermarket CAI. I think it was an improvement of 12g/s. Ill see if i can find it. Either way, ive read various reports with data that show it is restrictive, as Audi have gone for what works with a preference for what iis quiet approach.
