Trozzle

Ours are aftermarket .60 A/R. Mine blew my cooler piping. I'm cool. lol

we all know VL turbo owners don't do it for any mechanical reasons tho tutututututututu

Let's not forget about being able to play Sonic the Hedgehog on your car's stereo via an xbox 360 controller!!

Of course I'm not doing calculations, and I admit I'm merely making assumptions. If it weren't for the (very small amount) of exhaust gasses still turning the turbine when the throttle is closed, then the stress would be even less in my mind. Of course they're on bearings and can be accelerated at any rate in any direction, but it's still a decent force acting on parts that shouldn't really cop it...so if it's avoidable then why not avoid it just *in case*

I'm sure that on a steel wheeled turbo the blades wouldn't take much stress at all, but for a stock 15+ year old nylon wheeled turbo it might just be enough to snap fins.

Your opinion is invalid as you have shown mental instability when you sold that absolutely amazing R34 of yours. Shame on you. lol

farken hell stop hosting on imageshack. www.imgur.com so I can see it at work lol....or just upload it.

It's only annoying because this certainly isn't the first time he's said a BOV is pointless (or words to that effect) Automatics wouldn't have it due to the TB not closing between gear changes...but throttle off when slowing down would still warrant one I would have thought...ah well. I'm not saying that NOT running a BOV will definitely cause damage to the turbo, hands down...what I am saying, is that surely it will cause extra stress, potentially causing damage. It's fitted for a reason - to relieve pressure when the throttle is closed. Removing it might not have any adverse effects. People have also pushed 20psi through a stock RB25 for years without issue, yet people running 10psi experience problems. Doing something to the engine that differs from how it came factory is asking for problems.

You're getting annoying. Tell me, in as much detail as you can (with references), WHY Nissan among other companies installed a BOV from factory on cars. If there is no need whatsoever in releasing the pressure in the intake when the TB is closed, then why did they bother? If it's not going to do any potential damage or cause undue stress on components, are you saying that the engineers designing this shit are retarded? Perhaps once you're done justifying this once more for me (us), you should get onto contacting them (among other companies like Borg Warner who have gone as far as to integrate the recirc valve into their turbos) and tell them you think what they're doing has 0 benefit. fark.

If your missus actually works for Centrelink, then maybe it is. I could have sworn it was a 15 tho lol

Funnily enough, as of last night I'm also having boost issues. Induction doesn't sound much different, and no other loud hissing sounds, but I'm not making more than ~7psi. Even with the hose to the actuator disconnected, it doesn't want to boost... Time to rip apart all my piping etc.

Good to hear mate!

Kinda small compressor housing imo

I could have sworn he said it didn't make boost :S EDIT: I missed the 4psi part...only read that it drives normal off boost lol... Yeah boost leak imo. Unless you've somehow munted enough exhaust fins in the right way that it simply won't spin fast enough regardless of how much exhaust it flows

unfortunately not even like that Just ended up having to give her a lift home coz her night of study ended early, then cbf going out again and she suggested watching movies (oh joy)

I'm shit. Caught at home with the missus >.> plus just not feeling up to doing anything. I really need to get more sleep during the week

Nylon compressor breaks fins/completely shattered when throttle off after redline (maximum airflow), no bov makes all the air stress the bejeebus out of the compressor fins. The sound he heard was probably pieces of nylon wheel finding their way through his intake piping and through the engine then out the exhaust. This would explain why he doesn't make boost now. BUT!!!! He could also (and hopefully) have shattered the ceramic exhaust wheel instead. Would also explain lack of boost, as well as the "ting" sound as the ceramic found it's way down the dump pipe and into the cat. Unfortunately not running the BOV would make it a little more likely the compressor wheel died, but perhaps it's the exhaust wheel. Do you hear the turbo whine as you increase throttle, but without the sucking sound? this might suggest it's still spinning as the exhaust wheel is intact. Otherwise no sound at all could also suggest exhaust wheel goneskiz.

if induction sounds different (quieter) then boost leak more than likely wouldn't be it....

Also, running no BOV could potentially weaken the (nylon) compressor wheel of the stock turbo

ok, I don't know where you work lol. There's a VERY similar looking one at my (Centrelink) building's carpark.

Either the exhaust or compressor wheel in the turbo has shit itself would be my guess.

I thought R32 GTS-T ECU could be reflashed. Not real-time tuning, but can be flashed.

hell yeah nice!

should be "VR38DETTTT"

fark it's 403 forbidden here at work. Yeah quad turbo R35. That would be some seriously scary shit.
