Theres nothing wrong with 'dosing' and it won't wreck your turbo, as long as you're not being like a VL driving dickhead and deliberately stuffing around with your intake piping to get the most ridiculous noise possible.

I had a Turbosmart Atmo BOV originally fitted on mine, which got a lot of cop hassles, so went for a standard BOV blocked off, and it sounds a LOT better than a standard recirc BOV, which again sounds better than one of those utterly gay need for speed style SSQV's.

i have a 2835 with a stainless induction setup, but in a cold air box with a CAI.... when i blocked off the bov to rule it out as a possible leak, it made the full on VLT dose.....

put that bov back on REAL quick....! :)

dude... the Polarizer was the part which made the HDT's so special! That and having to run 22psi in the tyres for it to work, and not tampering with or removing it, so that the positive vibrations could flow throughout the car and turn a family sedan into a track warrior! I'm still hanging out to drive a Polarizer equipped HDT to feel the awesomeness :blink:

I dose all day all night on 18PSI, haven't seen the turbo die yet. Stock intake pipe, stock crossover pipe, GReddy TypeS BOV wound in so hard I might has well not have it there.

and no, I didn't use a HKS SSQV, that has no effect to dosing, unless the piston snapped and the BOV is now not functiuonal

dose ftw.

no BOV, big front mount, steel pipe off the turbo. the loud high pitched dose is normally curteousy of a 2.5" straight pipe straight off the turbo, when you start adding bends, and go to bigger pipes, the sound normally gets deeper.

the AFM being moved to the cooler piping is to stop stalling from the air reverberating through the AFM

What the hell is that noise? I've heard it twice now, both times from VLs. Is it some tricked out BoV?

If you ask me I think it sound ridiculous. My girlfriend was in hysterics for about 10min as we drove beside this thing.

Thanks.

i dont see how its so funny? it sounds mint

To the ignorant it sounds like a really wimpy/silly sound to come out of what looks like a tough car.

Like WRXs and EVO's, except they look like a girl's ride with girly ricey sneezies.

Do agree though, that fully hektik sound doesnt match the VLs. Something you'dexpect from Jap imports?

lol they are morons then.

+1

if that's all you're buying the car for then... fail.

ive had mine blocked off for a while now, doesn't make high pitched noises, just a clean whoosh sorta flutter. reason why i have it is that i noticed through hills/track, when changing gears it holds more pressure in the pipe and you get faster spool in to next gear but only high up in the revs as the air gets trapped and not released straight away.

lots of people say different things, this is just form personal experience.

here is my old car fluttering and doing its thing.

fluttered the entire two years that i had it. absolutely no damage to the car/turbo whatsoever. it fluttered so loud because of numerous induction mods and very high boost. factory blow off valve gave up but replaced with an aftermarket plumb back.

    • My thought is if you were just moving it forward and the upstream geometry remained the same, then no difference at all. But because the current one has the filter direct into the AFM inlet, you effectively have the best chance of a completely symmetric air flow profile upstream, and in, the AFM, whilst the aftermarket inlet thingo has a (small, to be sure) bend between the filter and the AFM. That would bias the flow to the outside of the bend (downstream of the bend) which might well reduce the size of the signal seen by the AFM, for the same total flow rate. Having said that: If you're proposing to make your inlet look like a hybrid of your existing one and the aftermarket one, such that there is no bend where the filter is clamped on... then I say it will be just fine. If there is going to be such a bend, then, if you can align the insertion of the AFM blade such that it is at right angles to the plane of the bend, then there is a better than even chance that the centreline velocity where the blade is will remain more or less the same, and the velocity will just be a little faster to the outside of that, and just a little slower to the inside. **This is not professional investment advice and you should consult a suitably qualified ouija board, tea leaves or the intestines of a goat for more accurate prognostication.
    • Hi Tao, Thanks for your reply.  It's been a while and I managed to get the valve stem seals replaced with the head on the car.  Unfortunately this didn't solve my issue, the car still smokes a lot after idling (to be honest during idle you can see a bit of blue smoke from the exhaust), same after deceleration. I will try disconnecting the valve cover breathers, do I leave the PCV valve in? By engine oil drain pipe, do you mean the turbo oil drain?
    • What about if you just give it direct 12v and earth?
    • Hi guys . Can someone help me  I bought an Android screen for my Nissan fuga but it won't turn on   
    • My guesstimate, with no real numbers to back it up, is it won't effect it greatly at all.its not a huge change in position, and I can't see the air flow changing from in turbulence that much based on distance, and what's in front of it. Johnny and Brad may have some more numbers to share from experience though.
