Weird noise over 3500 rpm
 

I dont know if anyone has experience this...
when i accelerate over 3500 rpm,,i start hearing a noise like
a louder version of HPFP sound, or a very small loosing metal moving so fast. It is noticable from the steer wheel/dash area. It is not the high pitch sound.
When I let go my gas,,the sound stop. When i press the gas over 3500rpm,,it happens again. I just had my service 3 weeks ago, and everything is fine.


Does any one experience this? Is it a big problem? Because i have a invidia N1 exhaust and i still hear it.

I am sorry if i post on a wrong section. I dont know where i can post this.

I bet it's the clutch return spring inside the master cylinder. I could not figure out the noise, sounded like engine to me and actually had me pretty worried until I stumbled onto an old thread.

Next time while it's doing it, tap the clutch pedal a little. Should just quit -poof-

so you mean next time when i gas over 3500rpm,,tap the clutch pedal and its over?!

If that's what it is, yup. I yelled out "sonofabitch!" when I discovered it for myself.

I will try to do it now. I hope it will fit like that....because it only happens occasionally....
Do i hold the gas over 3500 and tap the clutch, or gas over 4500, let go of the gas and do it??@@
Noted: but it doesnt have the sound before 3500 rpm

many thanks.

I'm more confident now that you say it happens only occasionally. It's about the right frequency too - 3500-4000 RPM.

Just tap the clutch pedal a little while it's loudest. If that's what it is, it will be obvious. It's like finding any old rattle, touch it and it disappears.

Are you sure it ain't the turbo spooling up? Or possibly VTEC?

Update: well seems like its happens occasionally again,and i tried to tap the clutch and it doesnt fix right away =/.

it only happens on 2nd and 3rd gear,,3500-4000rpm =[

It's called...

lol....i wish

i have an invidia n1,,and i still can hear the noise...

It's probably a metal piece vibrating. Have the car on the lifter and see if something's not fasten properly. What was serviced 3 weeks ago?

Damn, well, it was a shot. Can you record a clip?

I have a creak like noise in that rpm range. Generally 2nd and 3rd gear. Maybe present in higher gears as well, though everything gets pretty loud. I first noticed it last summer, driving with the windows down. IE, I bought the car new (150 miles) in February.

It only happens when I dip into the throttle. Just a creak/squeak sound. It can also be with a rev match downshift in that range with the clutch fully depressed. It happens every time. I kind of just figured it was something mechanical in the engine. I reckon I ought to set up an appointment at some time or another. The nearest Subaru dealer is like an hour away, thus me putting it off.

i will try to find a empty place and record...i cant do it around the neighborhood with N1 noise....

you are not along bro,,keep me update after u visit subaru.

for my case,,it doesnt happen on high gear tho,,
only 2nd/3rd 3500rpm +

Yeah. It very well may not happen above 3rd. Things just get loud enough that I wouldn't be able to detect it either way.

It was a 22500 mile service. Everything was green =[

it's the noise of VICTORY!!!!

What do they do for 22500 mile service in the States?

I believe this is normal. It is the variable valve timing (VVT) kicking in, so sort of like V-TEC. On a stock car it is probably fairly quiet but if you get a tune it will make it far more aggressive and it sounds like a tin can shooting around in your engine. Kicks in around 3500rpm-4500rpm where the dip is.

I complained in the past about this when I got my OFT but people seem to be OK with the tradeoff.

I had this. Interestingly, it was loud with my old OFT tune, but I just flashed to the tune released in February and I'm not getting it anymore.

check all fluid level,,brake,,tires,,basic electrical check, and floor mat @@ ....

well i didnt have this before or..i didnt notice it, it only happens occasionally. i got this car 3 months ago...
i didnt flash anything yet....unless my previous owner did...

i hope its normal. I got this car pretty stock,,unless the previous owners do something crazy stuff and OFT.

anyways to find out if he flashed or not?
