Hks Gtrs Whistle?

[green 33]

Hey Guys

I have just purchased and installed the famed GTRS and it has this loud whistling noise, when at idle and then reving the engine it will whistle through the air filter around 3000rpm onwards, but when you drive the car as you are accelerating it will produce the more whizzing sound (best described as similar to the engine noise sound you get through your speakers) does anyone else have the GTRS with a pod filter fitted that can tell me if theirs makes or doesn't make this noise or if it is normal.

i have tripple checked for air leaks, gasket leaks - and can gurantee it is not the fuel pump.

any help would be much appreciated

Cheers

Yes the GTRS makes a loud whistle/sucking sound because of the little slots on the intake (anti surge things).

It shouldn't be whistling on idle though

Cool thanks, was not expecting the turbo whistle to be so loud

yeah sorry should have been more specific, i meant when the car is not under any load and you rev it once it gets up around the 3000rpm range it will start whistling

Ahh ok. Yeah that's all perfectly normal. They sound sweet as

Yes i have a GTRS on my S2 Stagea auto, and when under way when i back off in say 2nd around town, (backing off only a little) and then holding the revs i find i can hold the whistle noise and can produce a rather loud whistle. But under full load it seems to be like any other turbo noise. Infact i reckon it is slightly quieter under load than the last turbo gcg that was on the car.

My HKS GT3037 makes a sweet high pitch whistle just like a jet engine starting up.

The old hybrid was more of a lower whoosh noise.

I will try and video it next time its on the RR from the front to see if I can catch the noise.

Yeah i might try to see if i can get the sound on camera as well,

I get the noise as soon i start accelerating.

Its the anti-surge housing. My GT30R does it too:

Done 280rwkw on its last run on a hub dyno at 1bar of boost. Not too surprising it sounds just the same, its basically the same as an HKS GT3037 Pro S
