newly installed Hi Flow results???

[SKYBEE]

hi all just wanting to pick some of your brains

i recently have just upgraded my car these are the following mods:

Hi Flow Turbo wont mention who off just yet

Gtr Fuel pump

ARC Front MOunt

3 inch dump back zorst

hks pod or a k& N

stainless twin dump pipe

power fc to go in but not in

and z32 meter

now the car was running fine before i did the hi flow stainless dump and fuel pump

but now i have put this turbo on i get a really annoying whirring noise as well as the normal induction sucking noise now i first thought boost leak but i have check and re tightened all clamps

second i thought turburlance at theh new dump but to no avail with standard on it stilll makes this noise its hard to explain what it sounds like very much like a hair dryer goin flat out really hi pitched whine?

the car makes boost fine doesnt fluctuate or any thing

i have check both compressor and exhaust wheels to see if they are touchin housings or are dammaged but nothing found

shaft play is wat you expect for a new turbo NONE

so what the hell iis this noise

because i want to get it sorted so i can take it to get pfc tuned!!!

any thoughts would be great

dude that sounds a bit like an unbalanced turbo. the play in the shaft wont seem like much when you check it but when it comes on boost your impeller/turbine wheel will be geting ramed against the housing. who did the hi-flow for you

Dont shoot me for asking but the whir isnt coming from the boot is it...new fuel pump?

How would you tell if the turbo is unbalanced?

I had a HKS 2540 installed on my car and it makes the noise that skybee describes but after the car been driven for awhile the noise seems to die down alot

The problem is you've installed a number of things at the same time. Makes it a bit harder to diagnose.

[DRFTR33]

its not that hard to diagnose an un balanced turbo the sound is very distictive. it is a high pitched ring that is only present when your on boost and you will hear it over your induction noise. you will want to work this out fairly quickly because if this is hapening on the intake side you can cause alot of damage to your engine due to the small metal filing from the impeller wheel, if its on the exhaust side it wont do any damage to you engine but you can take you dump pipe off and shine a tourch into the exhaust housing and you should see really small metal filling in the carbon. the reason why i ask who did the hi-flow is because i know of a certain company that makes mistakes like this all the time

Who a good turbo specalist in sydney? and how much would they charge to check it if the turbo is on the car?

[SKYBEE]

nah problem isnt i installed too many things cos i put every thing back to stock dump and air pod and like i know what a fuel pump sounds like and sheesh i aint that stupid

mechanical noise verses electrical noise to totally different sounds yeh well ive only done probly 150 kms max so hopefully i hasnt done any damage
