Title: Calling all gti 8v with induction kits or panel filters
Post by: lukesgti8v on 25 May 2009, 18:15
Hi people, ive tried searching for my answer but cant find one  :cry:

Ive got a agg gti 8v with the standard filter on at the moment but can't decide what to do.

Ive been looking at the pipercross air filters and panel filter as mainly i want to increse the performance abit more. So basically what im asking in terms of performance which is better a induction kit with a air feed or panel filter with a drilled airbox?

If anyone could tell improvements or losses they got from fitting either I would be very grateful.

thanks

I have a panel filter (Pipercross) with a drilled air box. I like it, sounds good and you can feel it slightly  :smiley:

I got a Green Cotton Filter with a drilled airbox and it does the job. Remember this is a cool air feed attached to the airbox.

hi you no when you drill the air box do you drill the bottom half of the air box

I only drilled on the drivers side of the airbox

i have a pipercross panel filter and a drilled air box

i cut the 90 degree angle trumpet off the air box and attached some duct going to a vent on the front bumper:)
works well

i drilled the box at the bottum and the drivers side

I'm gunna get a panel filter, not sure which one tho.... but does it sound alot nicer?? p.s. why would u drill your box? would it then allow crap to get in..

all performance panels will be the same so get whatever you want, drilling allows the air in faster and makes it sound much better.(as for letting crap in, a cone filter is completely open to crap....)

looks sick them holes lol, I will get a panel filter just not sure bout them holes, the idea of a filter is to stop sh!te getting in, but with the holes drilled, whats the point of a filter at all, you'l draw all sorts of crap in. hmmmm

is it just me or do you not understand the concept of an AIR FILTER

umm how do you think the sh!te is going to get past the filter?

i agree shep i think he is missing the point of a ( AIR FILTER ) ie to filter the rubbish from going through
Title: Re: Calling all gti 8v with induction kits or panel filters
Post by: christomk3gti on 26 May 2009, 13:17
now now lol.... just checked my box, the air inlet pipe is at the top, so ok i agree it will stop the crap from goin through, i knew that, but as your drilling at the bottom (ie under the filter) crap can still get in through them holes? right? just confirm i'm wrong and i'll do it when i get the panel filter.
Title: Re: Calling all gti 8v with induction kits or panel filters
Post by: mumbles on 26 May 2009, 13:20
yes the crap will come through the hole but......

air goes in through holes - then through air filter - (clean air) goes through to engine.

sorted, now go do it!  :grin:

ps. khare, that pipercross filter looks badass!!

nice one, wheres cheapest place to get the panel filter from.... as i got an 8v... are the 16v's the same for the panel filter? I'm thinkin of a piper cross one.... cheers and sorry for been bit dumb, just got up lol anyhow goin 2 work :-( 2 til bluddy 10.... or is it 2 - til when? hmm cya guyz

Sound level increases obviously vary massively depending on how much of the LOWER section you remove, experiment with if by drilling a few smallish halls on the lower wing side of the airbox and increase until you're satisfied with how it sounds.
As for allowing extra crap into the sytem this shouldn't ever become an issue if you're only drilled the lower section as this is before the actual airfilter. Just make sure you don't drill the upper section of the airbox unless you liek you engine breathing pure dirt!

I've got my pipercross panel filter at hand, going to drill some holes in the airbox on the drivers side, one question.... Do i need a cold air duct or is this optional? if needed wheres the best place to route the duct. many thanks.

Cold air duct is optional, but beneficial ofcourse.

I'l get a video clip of my induction set up sounding sweet so you can hear it  :smiley:

looking forward to it, one more thing khare.... Can i leave the original air intake pipework in for now? or will i need to remove it... if i remove it do i need to block the space...? if this makes any sense :)

yeah you can leave everything as it is, but the pipes that come with the airbox restrict it, so its best to get rid of them, both the one going from airbox to wing, and the one inside the airbox, on the top half.

just drilled bout 25 7mm holes in it gunna whack it on and test it  :laugh:

can i make a few suggestions here,

although drilling the airbox is great for noise it really doesnt give much extra performance. due to the heat in the engine bay all you are doing is drawing hot air in. if your only after a nice grunt then fair play.

performance panel filter with a cold air feed is the way forward. its pretty straight forward to rig up. ive done various testing on this and the heat generated within the bay is incredible.  also smoothing out the air box and removing sharp edges will make a difference, seen a few mods in the past where a home made heat sheild is used to protect the airbox to.

dont get me wrong i previously drove round for a year with a drilled airbox but now im after more horses solooking for all the gains i can get!

Do you think hot air will make its way to the airbox at motorway speeds? Agreed that possibly on a dyno, even though it was a big fan infront of it, but at motorway speeds the radiator and airbox is blasted with nice cold air.
Drilling the airbox improves the performance, and thats a dyno proved fact.

Blazin.... I gunna get a cold feed pipe, have u or anyone got any photos of how it is routed? or explain :) Just went for a lil spin, think it wants more drilling :)
Title: Re: Calling all gti 8v with induction kits or panel filters
Post by: BlazinGTI on 04 June 2009, 15:57
alright mate,

obviously at higher speeds there is more air flow passing through the bay so in a way you are correct. problem is (well not really a problem) most people dont drive at motorway speeds all day! dont get me wrong im not slagging people off who drill there airbox just pointing out that greater gains are had from a cold air feed.

blazin - where the best place to route the duct? thanks pal

haha, being an 8v as you know there is plenty of room within the engine bay to fit some ducting, im lucky enough to work for an engineering company so got myself some heat resistant flexi-pipe. it runs down to a flange in the front bumper which i made out of alloy. obviously you want to drill a hole in the base of the airbox the same diameter as the ducting, make sure its sealed and then find a suitable path to free flowing air (front bumper) , no pics to hand mate but ill try to dig some out.

if your suggesting people drive slower more then there is less air flow into the engine bay a cold air feed is going to do not alot more... if you want real performance and not just wanting to be a cheapskate then buy a closed induction system with cold air attachment so it is always sucking in fresh air.

I'm gettin some duct from work, heat proof (from a Dehumidifying Drier) **I also work at an engineering company** Ive had a look and can route the duct from a hole in the airbox (when i get time) with a piece of gauze fitted inside the airbox (to stop birds gettin in) haha, then route the duct to the front checkered grill at the bottom of the bumper drivers side. below fogs/indicators.
ohh and shep - I'll call u sarky from now on.  :grin:

heh, Will my theory work m8? Also, as i'll be probably using the (already cut out) for the original air intake, (removing all pipework) and putting my duct there, would it make it sound louder? **Note i dont want it toooooooooooooooooooo loud** just a nice tone.
