Hks Gtrs Whistle?

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 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:

Sounds just like mine mate. What was your boost and power?

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 ;)

      Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.

      I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.

      No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.

      Can you mount the ATTESA pump in other locations?

      Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!

      You think its the AFM? I know its a common issues on R32s. I find it coincidental how this issue raised right after cleaning the fuel system. As everything except the fuel system was fine before. I tried running it with the IACV unplugged but did not notice a difference and still stalled. However, the RPM gauge is not in the cluster right now, so I will need to connect the laptop again and use Nistune to check the RPM. I will check this weekend.
