Unless you are really worried about such a small amount of extra performance gain, and it will be very hard to really notice it and it will be very small.
To be honest, unless you have all the other parts of the equation with power increases with turbo engines , just fit a a more free flowing panel filter in the OE airbox.

just my input from similar usage in B7 turbo.

 

Bare cone filters are also more susceptible to heat soak and warm air in the engine bay being drawn into the Ic's , at least with the OE airbox there is a level of shielding, not a massive amount but some all the same.

with standard or semi modified cars you'll be pushed to get any benefit from a cone, maybe even some negative effects.

 

I've a Stage 1 tune and a 2,5" sport exhaust sytem after the cat. That's about it. Right now I've the lower part of the airbox still in place, with a K&N cone filter in it

 

All down to you really , i don't think you're gaining anything with it the way it is other than drawing in more warm air than you need plus the increased noise level which you dislike .

When audi designed the engine they factored in air flow etc required and fitted the airbox accordingly, I agree it's a safe route but works for most of us on standard or mildly tuned cars for road use.

Yes, the more airflow the better but it's all relevant if you get my drift.

From my experience fitting a free-flowing panel filter in the OE box with the lid is a very good option and you don't get the noise.

Just my input and I'm sure many others will disagree left right and centre.

 

I'd be more inclined to be keeping the intake charge temp as low as possible over a slight gain in airflow which has a questionable effect at your level of tune.

 

Yeah, guess it's a matter of taste. Only downside, I'll have to pay about £60 for the airbox :lol: Didn't come with the car.

 

There is allways a downside.
best of luck with it.

 

Here's something from the forums "resident Guru" that may interest you...https://wak-tt.com/mods/inductiontests/ ... ntests.htm

 

Nope still not convinced to be honest, maybe on higher stage tuned engines it will help noticeably, on standard and stage 1 lumps etc i doubt you will notice any difference at all, it may say 5-10 but that's ECU, not actual driving, stick one in and drive, any difference to the driver, very unlikely except in his head.

Over on the a4 B7 forum the same questions gets asked all the time, wack in a cone filter and you get XX extra ponies,
you don't, it may say get extra power etc, been there done it and if there is any gains you don't notice it.

Are you really going to notice 275bhp over 270BHP, no, we all like to think we do but that another story...lol
graphs are all very well but seats of your pants is what we're all after.

still, we're all different have different expectations from modified parts, whatever works for the individual.

 

Typical.....I had a standard box in my Garage for a year - tried selling on ebay, facebook etc for £30 with no takers. Junked it a month ago in a garage clear out. :? For my 2p worth, I have a cone filter on a mapped 225, and I love the whoosh/dump sound. Horses for courses I guess.

 

indeedy, all down to personal preference which s the most important part really.
have a good one.

 

Even with Data that says a panel filter in a oem box does nothing.... your not convinced and prefer to run by assumptions and conjecture. :lol:

You can not do any more that take a single car and try some back to back tests to offer a real world samples and actual data, yet want to not believe it.

Panel filters in an oem airbox alone, do virtually nothing as the restriction is the box design.
Wak box does something better than oem
Open cones even more so!

If you understand how the air mass meter works, you'll understand that the flaw in the heat soak argument the interweb loves to propagate.

You dont like the open cone noise, try the Wakbox as more silent but less effective option but the facts are open cones ideally with a velocity stack base are better than the oem airbox and heat soak has never been a problem in cars Ive tested as, if that were true then the air mass reading would drop and in all cases they havent.

I''d only consider that if you spend a lot of time in traffic then bay temps will get higher and recovery from airflow as you speed up may be marginally longer but overall gains have been measured going from oem to open cone tests. I also have two temp probes in my engine bay measuring temps at the air filter and near the brake fluid resevoir permanently installed to see whats happening if that gives you any confidence that I'm trying to have some science behind the recommendations.

 

So on a standard or stage 1 tune ,on our roads without driving like a racer there is going to be a significant and noticeable improvement in output and performance.
I don't doubt your data, looks really good to be honest but i question its effectiveness in a general driving situation, not driving like a track day god on normal roads.
Is it worth it on a road car and will it be noticed that much ,i don't think it will, but hey Just my opinion and we're all entitled to one data or no data.

 

I'll try the wak box and see what occurs.

 

You are of course entitled to your opinion and....

Without a remap custom stage 1 / generic stage 2 etc, I doubt you'll get an increase in maf g/s.. I know the B5 TIP has been known to increase by a few more g/s without an accompanying map.

But to be honest, these ECUs are so simple to remap, you'd be a fool not to accompany a Map Update with a decent Cone with a B5 oversized TIP, 3inch Downpipe, decent FMIC - mine actually reduces AITs as the car speeds up WOT (even at over 30psi), others increase the Temps and are no better than stock dual SMICs the AITs shouldn't exceed 30°C otherwise ECU intervention will retard the timing = no power.

I dont believe a stock TT panel filter can manage much more than 210g/s this is why REVO say you need a decent oversized Silicone TIP, Air Filter, downpipe, FMIC for a stage 2.. and state that stock TIPs collapse under boost... as if the filter restricts flow something else needs to give.

I do understand people's expectations with a new extra flow filter, gives nothing extra.. but that'll be either N/A engines or unmapped low boost engines.

The worst case is when someone maps a car with a Filter restriction... then changes the filter when they get home.. the remap'r made so much effort to get as much air as possible, as soon as a Cone filter is added it goes into overboost limp mode.

REVO STAGE 2

highlighting that you can spend 1500 to 2000 quid on a V6 3.2 TT engine for virtually no more power.

Full exhaust for a VR6 is going to be 800+ isn't it and a cold air intake for a N/A another 250+

And to change gear a bit quicker and rev a bit higher.. another 300... it's lunacy...

 

Great reply chap and exactly my point.

 

Again there is a bit of conjecture ......

Ive mapped many cars and I do pre mapping logs (where possible) and pre mapping leak tests.

FACT - Every healthy 225 I have logged with a B5 TIP and an open cone filter
Logs to a fairly solid 238-245 bhp, and I did one this weekend as well

Its almost a certainty you can get to QS power levels with those two mods alone ( midrange torque stays at 225 levels)

You will get better than a few HP with good mods on a stock map.

 

Great reply chap and exactly my point.

The only thing for you to do is do your own research/data logging as it's clear that don't believe anything that you can't understand or prove yourself.

That's interesting... I do recall Tuffty etc saying 'it's been known that a B5 TIP can add 10bhp on its own' I assume it is just getting to 6800rpm instead of running out of steam at 6200... which I expect is where the HP is coming from if the Torque is the same..

Far from it, the original post stated any noticeable improvement.
Forget all the data and number chasing, numbers can be crunched all day long but the question asked was, is the difference between a cone and an oem setup really going to be that noticeable on a standard or stage 1 tune.
from a seat of the pants driving standpoint, i doubt it will but if you want to just workaround based on data then it will be a rocket ship if you want it to be.
Different game altogether if we are talking serious tuned setups which i agree need increased airflow to get the BHP returns etc, but I'm not talking about that.

Is it worth it, depends on your viewpoint.

cone on my tfsi with 034 intake pipe plus remap , uprated IC, HPFP , HFC etc
Cone accounted for about 5bhp on the scale of things and up to stage 1 it made pretty well no improvement at all.

Anyway, I'm going to be shot down in flames whatever but everyone is entitled to there view on a subject.
There is driving by hands on experience and driving by numbers , sadly the two do not always equate to the same results.

 

I don't think the 'seat of your pants' is a good enough judge.. you get used to speed and acceleration, and so many other contributors come into the seat of your pants, from environment, road surface and even clothing.

Why do you think so many YouTube videos have 'taking my mom out in my GTR' one is screaming and the other is driving one handed looking out the window.

That's why people start with a 600cc then move to a 1200cc a year later.

 

So Rob is not wrong is his perceptions but I can say this from my own stats.......

8-9 out of 10 cars I see have leaks these days .... they are old and lovingly modded but lacking in application of experience and good checks.

So only 1-2 out of 10 people can add a TIP and induction and genuinly say the car feels more responsive even if its a 5-10 hp gain they generally will feel a lift in the car staying on boost as opposed to dropping off as much.

However that 80-90% of cars out there that will do their mods over an already flawed setup and not feel they have gained much.

I get it all the time , this weekends was no exception,... cars running fine..... but you have 3 major leaks and are aound 0.2 bar down on boost with a "boost change only!" mild remap thats trying to compensate on the air dropping out the pipework... and your N75 needs renewing.

Leaks and ebay map, bad n75 were the foundations over which mods were added to the car. And this is very very common... 80% of peoples opinions may be based on bad foundations so you really have to understand the basis people are posting over before making conclusions on web posts .

The Minority really know their car is sound, the majority just believe it is because their mechanics friends dog can sniff out a pipe leak and he didnt woof at the last service. :?

Shot down in flames for having a different opinion nah, nothing wrong with expressing a different view on anything, it's always going to be difficult on a forum due not knowing whether some one knows there onions or not let alone what opinions are based on, it's a rabbit hole with many variables

 

Sort out your top quote tag

Otherwise, it just looks like your having a monologue moment.

 

Interesting read this thanks covering the common debates Ive had - cones sucking in hot air ruining performance etc..

My TT came to me with a REVO map and standard hardware except a 'performance' panel filter.

I've fallen into the hardware mods post software map category unfortunately but will be looking to WAK to hopefully sort that ASAP. My first mod changing to the B5v3 TIP had a noticeable effect on acceleration/pull.
