Strange Noise, Sound From Engine Bay

[bevo89]

hi all,

just another quick question as this one has got me stumped.

i have noticed, when i am giving the car abit, sitting up around 6k, full boost, it sounds like there is a small air leak or something aruther, or even i slight scraping noise. it is similar to the noise your hear when your window is down slightly and the air is rushing past, but not so loud. car drives fine, holds boost up high and low and there is no sight of the sound at low rpm.

has anyone had a similar problem and would be able to give me some pointers on wrer to look before i get annoyed and take it to someone to check over.

cheers drew

errm.. sounds like normal induction noise........

agree with strik3r BUT maybe just maybe, its getting high knock levels. its not quite the noise you have described but i thought i should mention it just incase. knock sounds like marbles in a milo tin getting shacked around so if thats what your hearing then go straight to a tuner without going over 3k RPM.

marbles in a tin??? more like an electrical type zapping noise..... lol u go get marbles in a tin and tell me if that sounds the same hahaha

could possibly be a very slight boost leak buddy check all ur connections intercooler piping etc....

yeah will do but i didnt thinkit would be a boost leak due to it holds boost strongly, but will certainly check my piping and what not.. and unfortubatly strik3r, im new to owning a turbo cars but i do know a few things about them and its not my induction noise, its much much quiter then that. maybe ill take it to my mechanic and get him to check the knock sensors for me to see if anything is abonormal. add it deffinatly doesnt sound like marbles in a milo tin.

cheers

what sort of intake setup do you have ? Pod or panel filter ? FMIC ? what sort of pipes are you running? all of these things contribute to the sound your intake makes.... soooo it might sound different to others you've heard.. get a mate to record a video on a phone or something if you want us to give you a better guess.

all im running is a HKS muchroom pod, with a front mount with alloy piping. its not a loud sound like the induction noise is, its only very slight and only at high revs as i said and you can only just hear it, but its just enough to get up my nose because i hate having things wrong with my cars, even though they are really mineute,

marbles in a tin, 'electric zapping', what ever dude! it sounds to me like knock so id be getting it tested asap mate, or you might just blow your motor up. good luck.
