Strange High Pitch Wistling Noise When Spooling

[D_I_F]

Hi Guys..

Just before new years a friend and I installed my fmic.. its a R34 GTR front mount..

Ever since then when the turbo spools up I get a very high pitch wistle sound..

As my friends would put it.. it sounds like a truck turbo.. Its extreamly loud!

Any Ideas on what it could be??? All the piping is clamped on pretty tight.. and im not losing any power..

I just dont want my turbo blowing..

Cheers,

Corinne

z0mg turbo?!

Umm.. whistling would suggest that perhaps it's either a gasket or one of the pipes leaking air. I'd be leaning towards gasket

Check the blow off valve as well if you're running one

Stock bov.. Havent touched any of it except fm and exhaust pipes.. which it only started when the fm went on.. Other then that my mechanic does all the engine work..

Pretty common problem

Tighten up ALL your hose clamps on the intercooler piping. Not hard, won't take long, costs nothing.

If that doesn't work start thinking about gaskets.

Hmm.. Im pretty sure we did them as tight as they would go! But I will take a stab at it..

double check all the pipes and the intercooler for cracks

Sounds like a boost leak and it could even be a cracked pipe or intercooler or lose clamp or even a hole in a hose joiner.

does it sound like a vaccume cleaner thats blocked?

Boost leak for sure.. check the cooler it could even be cracked

One easy way would be a smoke test but I don't know how to do that at home without a smoke machine.

smoke test.....how about using the decarboniser? $20 from subaru. i had the same noise and when ever i used the that de-carbon spray thingy the smoke would come out of my exhaust manifold. broken studs and buggered gaskets. all fixed and problem solved.

oh no. you need to tighten up your turbo. the bolts are loose. and it will fall off. well not literly. but if you get it now. you can save the gasket.

[paulr33]

do you mean the kettle whistle noise?

mine does that, since the fmic went on

its a crappy chinese core and it just whistles away

Yesst thats what it sounds like..

how is it mounted (in terms of the front bar)

my front bar (series 2 one) was cut up a fair bit

and was a bit of a hack job install

i think the whistling may be coming from the cutting

and air passing arround the core / air ducting etc..

the easiest way to check drive along at say 50km/h

clutch in, let the idle engine

if you can hear whistling, its probably the core / front areodynamics making it whistle.

my 33 whistles quiet a lot, very audible

somewhat amusing as well

its the kettle car
