Well have a look at the induction hose to start with that may help

Check the hoses for any splits ,any that may not fitted or clamped down properly.

Is it just when you cruise or does it happen if you give the beans through the gears

harrisonl84

yea you got a good point lol, nah only really happens when cruising for a few seconds or put my foot down in like 4th or 5th to pick up a bit of pace.. is really annoying not knowing what it is tho..

I've the same problem, only happens when crusing and just on boost, let my foot off accelerator and it goes away

harrisonl84

yea exactly same as me!

harrisonl84

doesnt effect power or anything tho

Nah doesnt affect power, i've always thought it was the induction like, nowt serious like turbo on way out as thats a much more noticeable whine, more high pitched.

Mines a 1997 WRX nd all

yea your right about noise i thought it could be turbo at first but been the same for 2 mnths now no probs. Although my car is tappety how about yours mate?

Nah, mines quiet as a mouse (except for the whale of course).

So it should be like, i've just had it into Subaru for a £600 service, belts and all!!

Aye only had mine about a month or so like, whats your plans with it like??

harrisonl84

I had mine for about 7 weeks now, runs fine although is tappety when cold but quietens when warm. What mileage is on yours? and is it an import? Not really got any plans just want to fit some nice wheels and colour code my skirts.. yourself?

harrisonl84

alright guys drove around a hundred miles yesterday and the whale under the bonnet lol is getting annoying, I decided to have a look thismorning. Seems there is a gap from where there the tubing connects onto my induction kit. would this be a likely cause?

harrisonl84

Hi mate did you ever work out what the noise was??

M4RKG

iTrader: (22)

Nope, but since we last spoke i've fitted a FMIC and Induction Kit with ali pipe leading to MAF/Cone (not silicon hose)... and the noise has gone.

So chances are it is going to be your induction kit, have you still got the standard airbox etc? Why not try swapping back and see if it makes a difference. Would defo look at sealing that gap whatever you do as your induction kit will problies be doing more bad than good if its not as air tight as possible

harrisonl84

good to know thats the problem, by the way what is fmic? and unfortunaltely dont have the original pipes as car came with induction which i want gone really. prob just guna go for green panel filter.

Front Mount Intercooler... induction kits are fine aslong as you keep it in a cool part of the engine bay, or in the drivers side wing. I've had to keep mine in the engine bay but have made a box out of ali sheets to shield from the heat so takes in nohing but cold air

harrisonl84

ahh i see, nice 1. yea fair enuf making a heat shield good idea. May have to see if they sell them any where.. take it easy good luck with the car.
