Purely after noise, but hopefully no loss of performance. (chipped)
Better judgement doesnt change the facts.If you make a less restrictive path for the air to flow through it is better for your turbo.
If the air is colder you will make more power,albeit only a tiny amount with an air filter change.
You also get a filter that does not need changing and doesnt clog up as quickly as a paper one therefore loosing power,the gains are not just bhp/torque.
An engine is an engine and they need cold air for better combustion,or is the S3 engine special?
Wasnt Glens a smoothed/modified airbox with a big cold airfeed?
Purely on performance gains you are not going to get much,might get a faster spool up time if your lucky.
I do have one for sale if you want it,guaranteed +25 bhp gains
And yes your right my GT4 is the mutts nutts in comparison,never been beat by an S3 and doubt it ever will.
Just out of curiosity what power will flow through the airbox,standard or modified?
But at £100+ vs a new VAG filter every 6 months...is is better?
If i wanted an S3 i could buy one tomorrow,but i dont so i wont.I was actually going to buy an S3 when i sold my A4,but couldnt find a nice one and then when i did find a nice one i went to look at it in my mates 330ci which totally blew the S3 into the weeds,so i brought the 330ci instead and was so glad i did.
It amazes me why people think others cant afford an S3 just because they dont want to own one.
.
And incase you missed it the original poster was only after noise,which you will get more of with a cone and only loose power if it is a crap design.
280-300 BHP seems to be no problem. Standard.
I'll say again, modified will add nothing to write home about on the dyno, as there is nothing restrictive about the standard airbox.
Strange,i have just brought a nice big cone filter rated at over 500bhp for £39.95 from K+N,so yes it is better.
How much airflow does a 6 month old paper filter loose compared to a brand new one?
Better, how exactly?
Because it's bigger, shinier, more bling and has K&N on it?
Because it absorbs more heat?
Because it makes more noise - therefore the car must BE faster?
Nothing.
Not even anything noticable over a year.
They can last 18 months and loose no more than a BHP or two - less than a cone looses in heatsoak in fact.
Change them every 6-9 months and you'll have no losses at all.
Even at 280 BHP/330 lb-ft.
Proven.
Dyno's are nothing to write home about at all.
In one week i tried 4 different dyno's with 360hp,330,365 and 301hp.No changes were made to the car and there was no drop or increase in performance on the road,dyno's are not the be all and end all.
What filter would you use on a 400hp S3?
Bigger and allows a shielded straight intake to the turbo
allowing the turbo to spool up nearly 500 rpm earlier making for a faster car and removing the battery to the boot for better weight distribution.
Even at 280 BHP/330 lb-ft,wow that much.
Shielded...not sealed. Good plan.
Bigger is better is it?
Again, for the hard of understanding: If the standard inlet is not restrictive, fitting a cone filter the size of Manchester isn't going to give you any gains!
Why is that so hard to take in?
Spool up earlier...not on an S3.
Tried it...didn't work.
Battery to the boot - done that on my GTI for weight distribution purposes...where you actually get a benefit.
On a lardy S3...come on!
Sp ypu have more power from your nasty Jap cratation.
I'm impressed.
Stop the petty penis waving and counter the points ditectly with your experience of S3s...oh yeah, you can't...because you don't have any.
How did you manage to get a straight intake on an S3?
And actually yes bigger is better as my old filter ran out of at 340hp and the standard airbox earlier still.
Nasty Jap creation which makes me smile every time i drive it.
Shielded,sealed.You say potato.

Thats not a straight intake,thats straight to the maf not straight to the turbo?Shove length of MAF sized tubing onto the MAF and have it hanging over the wing whilst you dyno, to see if you get any gains - with a big cone filter on the eng, in the airflow of the cooling fans.
And the gains were?
Nothing.....
Shove length of MAF sized tubing onto the MAF
An insulated and sealed system - like standard - makes sure only cold air is ingested, and that it stays cold as far as the turbo...which is important where the S3s poor ICs are involved in then cooling it down, post compression.
Potato vs Sprout, really.
How heavy is the battery on an S3?
Right up front behind the headlight and infront of the front wheels,or just behind the rear seats?
Must be better even on a lardy S3.
Thats not a straight intake,thats straight to the maf not straight to the turbo?
Which is not the way to do it even if that was a straight intake,you should have the pipe going to a larger diameter upto the filter like a cone shape.
And if you are going to do it right the cold side boost pipes should also be insulated from all the heat under the bonnet.
Battery is heavy...but even when removed you have to leave the connection box in place that normally sits on top...so sure you can loose 5kgs or more.
You could say the same for the 4.5 litres of water that sit in the same place on the other side. You going to remove that too?
Have you ever actually looked under the bonnet of an S3 before giving us your tuning advice?
The TIP reduces the size...so you do indeed have a reducing bore as the air approaches the turbo.
If you have a big cold air duct (say 4") going to the Maf, TIP, turbo you will see that in that set-up you are again reducing the bore, technically increasing air speed as you do so.
You can't do a proper straight inlet to an S3 K04..
How exactly did you try this?Spool up earlier...not on an S3.
Tried it...didn't work.
You can't do a proper straight inlet to an S3 K04...but I still don't believe that with the size of turbo fitted, it would make a bit of difference, so well designed is the standard set-up for the standard engine.
As does re-locating the DV take off to the cold side to not dump hot air back.
...which I had also done.
I know what DID and DID NOT work based on me actually buying parts ant trying combinations of what IS possible.
There are alot people on here and on other forums who base their entire arguements on other peoples findings some of which are correct and some are complete crap as the tests were done WRONG in the first place so could NOT possibly be accurate.
I agree people should make their own minds up but if you do actually get a gain from something incorrectly tested by an expert on a forum dont post it up because no one will believe you and refer you to the said WRONG tests that they like to believe as gospel.
either way you learn by listening to others that know more than you do, in this instance I put my faith in Glen and a few others on here because they actually back up what they say with facts which any level headed person can make sense of....
on another note, it will be good to see what sort of 1/4 mile times your Gt4 puts out this coming summer.... purely for you to back up what you preach
James, maybe go and read through all of Glen's previous posts? He has some great stickied threads posted around this forum that backs up what he did to his S3.
At the end of the day, every S3 will be different. Something that worked for Glen may not work for me, or you. But if it worked for him, don't slate him for it...
I think people were genuinely listening properly until you mentioned the fact you don't own an S3 and are only comparing it to your experience of a Golf and your GT4. Shot yourself in the foot with that one I think.
What I would be interested in, and sorry for hi-jacking the thread but it seems relevant after this argument, is what are the best mods to do for the smallest cost?
From my limited knowledge, and reading up on other peoples experience, a remap and a milltek exhaust would be the best upgrades?

james0808 said:I was impressed until he tells me something i know to work doesnt work because HE has tried it and it did nothing only to then be told how he actually did the test,the clue is in the name "straight intake" not just shoving a piece of pipe on the maf and bunging a filter on the end.
Ferrari mechanics are trained to work on Ferraris. Are you trained to work on Audi's?
Do you own an Audi?
...and you clearly didn't read the rules on language and attitude to other users.
Goodbye.
I trust that's perfectly clear?
