Funny sound coming from my wastgate... is it serious?


Recommended Posts

Hi,

I had the temporary piping & welding (needed for VIC Roads RWC certificate) removed from my wastegate to exhaust on Friday last week. B4 work was done the noise level on boost was high, but similar to the sound of turbo spooling... with pipe fitted not much different. Now when on full boost it really does sound like my car is doing a fanny fart. Why is this so? Only the pipe that went from wastegate to exhaust was removed and then hole in exhaust filled and welded shut. I can’t notice any lack in performance and the cut on pipe is straight, not jagged or squashed.

I would like to get it sounding better than it does now. Any explanation, thoughts would be appreciated.

Oh… BlindElk I have your front brake lines if you see this. PM me and I will meet up with you and return. Thanks for your help. Much appreciated :P

make a sound file robin and post it up...

You reckon hold a mic out the window getting on boost and record? I 'm serious it sounds like a long loud whoopy. I will attempt after work and post tonight.

ok, Im not really following what you man mate... so some questions

Do you have an ext wastegate?

The wastegate was plumbed back into the exhaust... and now its externally venting (or a screamer pipe in other words)?

if so... then thats the noise they make man.

I have an external wastegate.

Screamer pipe yes...

But B4 I had the work done it screamed but not like it does now. It's like it's singing out of tune if you know what I mean? Maybee all I need is to cut again above weld where sleeve was placed and maybee thats causing the funny scream. It is pretty off putting and I bet would scare the shit out of a driver with his window down if was not expecting it... even better if done past an undercover >> ass ram!

LMAO

robin - dont need a mic if u have a digi cam of some sort... just whind the windows down and put it on the seat so its sheltered from the wind and let it record... then put it through movie maker and remove the video so u just have sound... or leave the video in if u want :P

    • So I'll put filler past the repair area a bit to make sure I don't miss anything. Then I'll block it until it's almost level, put the guidecoat, then keep blocking until it's gone. Then it's still wavy.  In regards to hitting the panel, I saw this video might give more context - Skip to 0:47 he knocks it down. But yeah I'm sanding until the guidecoat is gone then checking because otherwise my filler is still well above the bodyline. Unless what you're saying is I should put guidecoat around it early, surrounding the filler then stip once it's gone?
    • I refreshed the OEM injectors with the kit and connected it up. It now ideals okay even with the IACV removed. Driving still has the same cutoff issue like the 550cc injectors so the issue is somewhere else. I bought FPG's Fuel Pump Hanger. I will be installing it next, but it is not as straightforward as I thought it was with my limited wiring knowledge and no instruction on the specific model I purchased (FPG-089). I also got the incorrect billet clamp as I could not find info on the OEM sizing.
    • Stop looking at the garage floor, and turn the radio up a bit louder if there's any strange noises...
    • No. Turbo shuffle and surge/flutter are not the same thing. Specifically, on a GTR, turbo shuffle has a definite meaning. On a GTR, the twin turbos are assumed to be the same thing and to operate the same way, exactly. In reality, they do not. Their exhaust sides are fed and exhaust a little differently, to each other. Their inlet sides are fed and exhausted a little differently, to each other. Consequently, when they are "working" they are often at slightly different points on the compressor map compared to each other. What this means, particularly when coming on boost, is that one of them will spool up and start producing extra flow compared to the other, which will put back pressure on that other compressor, which will push the operating point on that other compressor up (vertically). This will generally result in it bumping up against the surge line on the map, but even if it doesn't, it upsets the compressor and you get this surging shuffle back and forth between them That is "turbo shuffle" on a GTR. It is related to other flutter effects heard on other turbo systems, but it is a particular feature of the somewhat crappy outlet piping arrangement on RB26s. There are plenty of mods that have been attempted with varying levels of success. People have ground out and/or welded more material into the twin turbo pipe to try to prevent it. Extending the divider inside it works, removing material doesn't. There are aftermarket replacement twin turbo pipes available, and these exist pretty mush purely because of this shuffle problem.
    • You can temporarily* use lock collars to keep it in place until you can do the bushes, back the nuts off, slide them in, snug back up. *temporarily is often for ever
