Debating on getting a intake for the car are they worth it ?
Thanks
-
Depends on your plans for the car, if your not going to map it or do any power upgrades then its mostly a noise mod, you will feel some difference but not much
If you're looking to do power upgrades Map/ exhaust ect... Then it is worth it, they help the flow and will give a decent BHP gain and make some very nice noises.

Okay thanks for that, i have had the car remapped already and have a milltek cat back, i will be going back after xmas to get a de cat and down pipe but debating if a intake is necessary.
-
If you've got that lot then I would say do the intake, then maybe a cooler at some stage and get it mapped again. But with the full exhaust you'll get a few BHP out of an intake. Its not totally needed but would be a good addition

Thanks for the advice mate, may wait for a 2nd hand one to come up cant justify paying £300 odd for a new one (cheap skate)
:grin:
-
Haha, it's not like they get any worse second hand no shame in waiting for a good deal.

I'm going stage 2 with just a panel filter. . .
I'm trying to stay OEM as possible and don't really want any whooshing noises entering the cabin.
Intakes also lose you a little torque lower down in the rev range :sad1:
-
Again, I've got just a panel filter. I'm pretty sure I remember all the big tuners say that you're far better off spending the money on a downpipe and sports cat than an induction kit. But this is for a K03 which is a smaller turbo so doesn't need a huge air supply to it. K04 or big turbo kits differ I would guess.

Just taken my mtc style intake off in favour of the oem air box.
My cars stage one. If anything it picks up a tad earlier and quicker. Not felt any difference further up the revs.
I'm hoping the fuel trims come down too.
I used the oem maf housing in my intake and there's a massive debate going on about maf placement as the oe maf is in a oval tube, while aftermarket are round.
Personally I'd spend else where.

Thanks for the advice guys!
I'll spend my money else where and if a second hand intake comes up I'll have it !

That's probably the most sound advice anyone could give you. :happy2:

Not a fan of intakes and I used my oe airbox with oe filter at stage 2+ with no issues. The loss in low down torque was enough to make me switch back. Id spend the money on something else as I only lost peak 10bhp by switching back but gained power back in the low and mid range. With the intake it felt like a vtec and all the power was moved to the high rev range. Great for track days but rubbish for a road car.

Was this on the "TFSI Tuning" Facebook page that Niki setup?
I'm tempted by the intake pipe & MAF housing to OEM filter :drool:
Wonder if a mk7 airbox would work?
-
See, I would like an intake at some point for engine bling more than anything else, but how much torque are we talking about loosing low down, percentage wise?
-
Not sure how people can complain about the low down losses from an intake with such a small turbo my peak torque is about 5k with a big turbo and i feel i have loads of power still low down for pottering about on the road
-
It was noticeable as I lived in a hilly area and I had to use more revs than normal to get the car moving. With a bigger turbo you will produce more power and torque low down than a smaller turbo so cant really compare the two. I believe that some people get lost in number chasing rather than a fast road car. Like the old days when people fitted kent cams with massive profiles; but it meant you had peaky power and had to rev the engine to get any power out of it. There was no flexibility with the power band and that's what makes a fast road car.
-
When I had my Volant CAI I noticed a few hundred RPM difference before the TRQ came in over the standard airbox, doesn't sound like much, but for regular driving I prefer the standard airbox.
I also thought that smaller turbos were better lower down as they spin up faster and the big turbo having all the fun up top?
-
What is it that results in the free flow induction pipes give less torque ? Loss of air velocity ?
-
Does going back to an OE intake get rid of the compressor surge that can occur? Interesting thread this. :popcornsoda:
I had an intake fitted (Revo) and it does what it's supposed to do, very good on track and it's what I asked for...good on track.
I've noticed the torque spread change and also some compressor surge is present if you happen to be in a less than optimal gear for the rpm.

I think with compressor surge is down to the mapping and how aggressive the turbo is allowed to spool. I didn't suffer this with the shark performance map but you raise a good point there. I had boost fluctuations when I had a k&n panel filter fitted; but that went when I fitted a paper filter. I wondeŕ if there is an element of maf sensor readings being sensitive on anything but the oe maf housing.
-
the surge is down to the open intake making the noise audible
and 56octy i understand what ur saying low down torque is what most are after in a daily car which doesnt spend alot of its life getting driven hard aslong as its progressive delivery aswell..
