hey guys, was at a mates house today and decided to put in a manual boost controller, went for a drive, put my foot into it just a little, it spiked... so i pulled over, wound it down... got back in the car, cruised for about 2 minutes then got onto a straight bit of road and gave it another squirt... it almost choked up, coughing and spluttering and so on, took my foot off... when i went to put my foot down again, i hear a noise like a siren, i look around only to find the sound is coming from my car... so now i cant make boost, no matter how hard my foot is on the accelerator, it sounds like its coming from the inside the pod filter... so i go back to my mates house and pull it apart, all the way down to the turbo blades, checked it and nothing caught in there or any of the piping, put it all together again but still making the noise... i took the boost controller off but still it makes the same noise...

SO... was just wondering if any of you guys have ever had this issue or know what it is at all... just lost my job two days ago so cant really afford to go and get another one... any help would be greatly appreciated...

Cheers

Guy

maybe, was a bit dark to finish the elimination process... so tomorrow morning ill check piping and all... spoke to hyperdrive and they reckon might be a leak on the manifold or exhaust somewhere... not sure, but the noise is really loud, like almost copper siren loud... just odd!

Be careful. If its the bearing then the turbo will be spinning out of alignment. Hence the fins are spinning into the housing. Slowly feeding ur engine small metal filings. Did the boost gauge move to like 10psi? or nothing? Blow IC piping = no + boost

yeah it did before it stopped... now it just sits on 0... wont go past it

If it was blown turbo, wouldnt there be smoke?

i dont think you would blow the turbo off that small amount of spiking unless it was already on the way out....

i put my $$ on IC hose or even a problem i had, with a intake gasket getting a pin hole in it...

^^^yeah i dont think ur exhaust wheel blown off will make that noise

check all ur piping for ur intercooler but even then, i dont think a leaking intercooler piping would make a loud whistling noise

      The housing it self made minimum differences, while the exhaust manifold made a difference. 6 Boost T3 divided will do fine. ATR43SS3ProR model in T3 .82 rear (TS optional) from March 25th will be more then capable of 450whp with excellent response.

      The boy crashed his Patrol a while ago, so he is now driving his mum's ASX and she is driving my Honda I initially said he could have the Honda to drive around (he's a good kid currently training at the police academy), but, his mum was quick in saying that he "will" take the ASX and she will take the Honda, he was a bit upset with that, he rates the manual Honda more than the automatic ASX (mums taxi), and I'm getting the feeling she enjoys thrashing the manual Honda around In other news, I'm looking at a MX5 NB series 2 on Saturday  I always loved my NB series 1, but after stripping it down because I'm a idiot it wasn't fun cruising or driving around daily, and Jackie refused to drive it, which was an issue if we went out, because her refusing to drive it meant I lost my designated driver if we went to a party, or dinner, or...... basically anywhere where I could get a glow on Yes yes, I may need a new job if I decide to buy https://www.seek.com.au/apprentice-hairdresser-jobs/in-All-Sydney-NSW Plus giving the Honda to the boy, which is my cunning plan, will give me enough wifey type credits to turn up in another car Meh

      Yeah I've just been checking it out on GTR registry and its the emerald green pearl (DS0) and only 610 made for S1 RS-Four V (if i'm understanding correctly) so I feel obliged to restore the paint to as close to original as possible!
