Ducting

digitalwolf · 28 Oct 2007 at 21:31

I need some ducting to run to the airbox on my car. Basically I've pulled the resonator out so it makes a nice noise.

Problem is, it just sucks warm air in from the engine.

I've got a K&N panel filter in the box anyway so any ideas where I can get some from?

I've tried wickes & b&q but they only do it for tumble dryers etc lol.

I'd like some 76mm ducting for my airbox. A small scoop to sit behind the grille would be great too. Just something to force air in rather than the standard angled intake that sits in a random place behind the headlight.

Check out raceland induction kits. It's an open cone, but sits underneath a scoop. Can be very effective on the correct car.

That golf looks and sounds rather nice!

It looks like hoover hosing ha!

but wouldnt you have to be doing very big mph to get any sort of ram air benefit? lol

as long as its breathing from somewhere cold youll be doing alright. whats your intake system look like without the resonator?

Mines got a gaping hole in it. Hence air escapes before it reaches the filter.

what diameter do you need ?

Got a feeling it's 2.5 inches.

what about getting a another hose and putting it into that hole where the resonator used to be, glueing/sealing it into place then running that hose to someplace cold?

is it possible to get a pic of a (focus, innit?) with the resonator gone?

Thats what I intend to do. Install a second pipe either underneath the current one or down by the foglight. Just need to remember about it being low when going through the odd flood lol.

well stuff like that aint too dear, i got mine (as per this pic) from a local ducting place on an industrial estate (about £4 for 2m, it was an off cut)

seal it to the airbox then run it to somewhere cold, much better than a drilled box (ive measured the intake temps..)

Arrhar, great stuff. What did you use to seal it?

Cheers.

my airbox has a 'warm air intake' that goes to the exhaust manifold... it is of no use to me any more so that was modified and the longer 50mm grey hose added so make it breath from somewhere cold.

the hose is held on at the back with a jubilee clip.

as for sealing yours on, id imagine most silicons/glues would do the trick

Ok thanks. I was thinking of using self amalgamating tape haha.

That CAF duting is more than I paid for the K&N air filter!

My original panel filter was clogged, don't ever think it has been changed.

It seems to pick up nicely on freezing mornings.

Relatively clean to be honest, throttle body was clean too. It did have a strange looking stain on it though, possibly sucked in from another car belching carbon?

Do you have a saxo mate?

Mine is a dirty grey colour ha!

I do indeed mate - 52 plate VTR.

I think the filter was changed on the last service and it's only done ~3k miles since then. Dunno about you, but my airbox was pretty much full of dead bees

Yeah, Saxo complete with insect graveyard haha!

The sound is quite good actually, makes me giggle a bit when I floor it

Well, just to inform you that I still cannot locate an air hose/ducting for the air box. I went to three places yesterday, none seem to have 2.5" just 4 inch plus!

Speaking to Paul/GT3, he reckons that there isn't a great deal of heat soak due to the resonator hole being quite low down.

I'll monitor it, atm i've seen no difference in performance or mpg but i'll be keeping an eye on it.

digitalwolf · 10 Nov 2007 at 18:57

Paul, what mpg did you used to get out of your VTR with the missing resonator?

digitalwolf · 10 Nov 2007 at 19:08

About 240 miles to 30 quid. Round town mileage as thats what I used to only do.

Was that giving it beans taking advantage of the lack of resonator?

It all depends what car you have. You could go out an spend £150 on an enclosed BMC induction kit and see no difference e.g saxo vtr.
Put a bmc enclosed, green cotton or raceland with a cone an a scoop on a vts and you will see a difference.

As for mpg, ive just got 58 miles out of a 5'er , mainly extra urban, a bit of foot to metal and a bit of urban.

Thats why id have another saxo again. Great on fuel, cheap to insure and hasnt been much hassle *touchwood*

Oh p.s. the ducting is stupidly priced on the bay also.
