Title: filters, cai's, just want it to be quiet and smooth
Post by: Dalo Harkin on 01 May 2013, 21:11: Hi guys,

Right, long story short I must have tried every variation of cai and induction setups

I swapped from a filter on the MAF and heat shield with cold air feed to a pipercross and dsg setup last month, the pipercross seems very restrictive, it's fine when going fast but when going slow <30 its a little stuttery and not happy, swapped back to the cone and heat shield and it's fine again at all speeds.

Any help, because I am sure other people on stage 2 run airboxes

Thanks

The filter is fine. It just has to suck through the pipe, behind the light then up to the slam panel.

The DSG upgrade is better, but the intake tract is tract is too far.

Post by: paultownsend on 01 May 2013, 22:31: Ps. The wak box is OTT. I took a hack saw blade to the intake corner , and opened it by twice the size. The DSG tube will still feed cool air, but it won't choke and can suck in more if needed.

VCDS proved a 4g/s maf increase and no increase in intake temps. With a silicone TIP it sounds ace without being OTT.

Post by: Dalo Harkin on 02 May 2013, 11:40: I've got the DSG intake on it already (soon to be for sale by the looks of it)

I prefer the car quiet, but you can physically feel it being starved of air at lower speeds

Post by: paultownsend on 02 May 2013, 21:12: It's starved because of the tiny inlet on the box itself. Then it has to suck around the airbox.
Disconnect the DSG pipe from the box to the headlight. See how it is then.

as you can see minimal restrictions!
i went OTT as at first i just did the corner with the air intake is. then i had a few ales.............. (il get another airbox soon and remove half as much next time)

IAT's however are not effected but MAF mg/s are improved. with a forge TIP it sounds subtle but purposeful.

i see this as being better than a Jetex type induction filter. It has the same if not better filtration, it can suck as much air as it needs, and it sucks in minimal warm air. the OE intake still feeds to it.

Post by: Wazzzer on 03 May 2013, 17:49: Bloody hell that's a lot to cut out. I might go with the cut outs on the wak box
Title: Re: filters, cai's, just want it to be quiet and smooth
Post by: paultownsend on 03 May 2013, 19:05: Yeah I went OTT but it works!
If just cut three ribs either side of the inlet
