Turbo air filter

TLindley · Post by **TLindley** » Mon Nov 28, 2005 4:19 pm

Hi all, i have a quick question about air filters.

When I bought my 480 turbo recently, it already had one of those 'universal fit' cone shape air filters, which has been fitted directly onto the air flow meter.

I know that where it currently is, the Air filter is probably losing power rather than gaining it, as its right next to coolant pipes and when the fan comes on, all that lovely hot air blows straight onto the cone.

Because the box has been removed (and i dont have it), theres a load of room behind the battery , where i could put the air filter. Problem is I dont have a pipe or anything to connect it to the Air flow meter. Anyone have any ideas or done anything similar?

Thanks,
Tom

I think your better off going to the scrap yard and getting the volvo kit which should (prob fallen off) the air ram pipe to some nice cold air.

otherwise your keep sucking hot engine warmed air up.

Yeah, i thought that might be best. What do most turbo owners here have?
Does any1 have a spare air box?

Tom,

ANC Salvage in Bolton are currently breaking a 94 440 Turbo which should still have the air cleaner assembly in it.

I'd get them to ship you this part,put a standard Volvo paper air filter element in,as the K&N high-flow panel filters are just a waste of Â£50.

Then,use some flexi ducting to your front grille.Martin Holmes cut a hole in his grille and poked the ducting in there.I just have mine sitting close behind it.

It works very well,noticeable on hard acceleration.

Those cone filters are shite indeed for our cars!Sound nice but thats about it!

I believe Pipercross's replacement filter is supposed to be quite good-i'm sure someone on the forum has one? Just replaces the standard panel filter...>>>Filter<<<
Quite reasonably priced too imo.

I didn't want to faff around with cone filters etc, so i'm debating the above filter, but i've already given it a cold air feed that pokes out behind the grille. Not a massive difference, but noticeable if you know your car well...

Could (if money is not a problem) get a CDA induction kit the filter is inside a carbon box and has a cold air feed to I think the kits start at about Â£150 but worth it, my mates got one on his C2 gt and sound good and increased power by 7 bhp (we rolling roaded it) and thats on a normally aspirated engine.

Check out e-bay or search for carbon dynamics/CDA

Yeah ive seen those cda things beforeand there's one called a viper or something. Well expensive but they do actually improve bhp (more-so if you have a straight-through exhaust).

On mine, the previous owner has attempted to put a cold air feed pipe through (fed it much like DT480M has done) except A. its plastic, meaning it will get hot and B. the diameter is about the same as a 50p coin (i.e tiny) meaning it probably does nothing. He's cut a hole in the front bumper (the black bit) for it to go, so i'll have to keep this now if i dont want a huge hole there, but i need to get some new ducting

Ive seen you can get aluminium ducting at halfrauds or motorworld at rip off prices, but its pretty much the same stuff you can get at any hardware store or plumbing centre. Whats everyone else used?

Hardware store/plumbing stuff. It's a lot cheaper and same stuff

I got mine from B&Q, half a metre, only Â£2.99. Same, for only 8" in my local 'Car Centre' would have cost about Â£9

what diameter you use?

I think it was somethin' like 3 3/4". Sounds alot but isn't really. Not massive, but not oo small. Just big enough to fit over the black Volvo piping that goes to the airbox.

Indeed!

And make sure you can shape the pipe so it ovals as that bit on the air box is oval

Gotta a proper one fitted and had to move the battery into the boot but it worth the hassel got it wheel spinning in third gear in the wet. By the way it's for sale, after the engine gave way, i think, it just sounded really rough!!

Really simple solution here guys.....search for 'carbon induction' on eBay. There's some cheap ones with a carbon body and a chrome horn. Attach ducting to the chrome horn and you have a viper for about Â£40....job done! .....well, on the cheap at least.

A cone will always be better than the std airbox as long as it is shielded. If it isn't it will not.

I'm currently making a universal carbon airbox for my GT4 that would probably fit the 480.....ill look tonight. This is going to be totally carbon and allow any 3" intake cone.

i personally would leave the filter where it is and just 'box' off the area where it is with summit like tin sheet. this will keep the air feed cooler, and keep the intake lass restrictive, best of both worlds.

hope this helps
