just wanted to put to the vic boys on what type of BOV sounds the best and whats being able to get a way with the cops, i mean plumb bcak ones or the venting ones (they sound awsome) ?

also can you have the origanl one still in place with an after market one hidden somewhere else ?

I'm assuming that keeping the stock BOV is so that when the cops look under your bonnet you tell them that you can show them that the BOV is stock? Is the stock BOV venting or plumback? If you come across a cop who knows what he is talking about and hears a venting BOV then you show him a plumback BOV then you will most likely be caught. Also if a cop knows his stuff then there is a chance that he will se the aftermarket BOV also, just thought you should keep that in mind.

Also, correct me if I'm wrong but don't most people change the BOV in their cars because when there is increased boost pressure the stock BOV opens before the throttle plate closes, so having a stock one still connected (unless its glued/welded shut) will defeat the point of purchasing an aftermarket BOV....

Also I think that the only legal aftermarket BOV's are the plumback ones also. :D

you mean the flutter noise? that noise is not considered good its the air hitting the spinning compressor wheel and its getting chopped, cars without a bov are known for this, like the vl turbos. its fairly common to kill the turbo eventually from the flutter at least i think it is

i have a pod and it does have a nice sound but what i was looking for was one that made more of the "dirdirdir" sound not just loud hissss.

If you want the flutter sound, you can just block off the standard BOV, it will make the sound.

Its not good for the car, the flutter noise is the sound of the BOV not doing its job. Everytime i hear a car with a BOV that flutters, i laugh. Who would pay money to do something to their car that damages it?

If you want more info on this, do a search on flutter. This topic comes up at least once a week.

I've got a HKS SSQ, Only reason - got it new & very cheap and stock one was stuffed. Been driving the car for 13months now. No cop problems (yet), no stalling problems (Apexi SAFC 2 & heaps of other stuff).

As Rhett says in the previous post, "flutter" is no good for the car, just use a good condition stock one, or aftermarket if you want noise & to replace or unwilling to fix a damaged/non working stock BOV.

Blitz Dual Drive bovs have a nice sound and you get a little sus filter addon for them.  I'm curious about the greddy type S bov.  Can anyone describe what sound it makes if any?

hey, just thought you'd like to know about the GReddy type S BOV, i got that on my series II, im running a front mount and about 12 pound boost, it sounds awesome with my hks pod filter. ive adjusted it to make the flutter and its heaps loud. you can also have it so it makes just the whoosh and a small whisle at the same time.. deff an awsome BOV

no stalling probs either.

A mate bought a TamK.O. copy of the Greddy type S off ebay and bought it to me to fit.

I thought it looked like a really cheap copy but I had a look at a genuine Greddy one at Autobarn and they appear identical right down to the gasket that comes with it.

It was about a third of the price of the Greddy one.

It wasn't very loud with the stock air filter but is pretty loud with a pod.

It flutters a bit backing off from low boost but has a solid Pssshtt from higher boost.

The spring adjustment changes the sound quite a bit.

though i aint got my car yet as its due to arrive shortly, ive gotten prepared n got me self a fake HKS SSQV bov off ebay for abt 1/2 the original price (i paid 210 inc postage.) it looks real enuf to the original one too, tho the only give away is the HKS engraving and the black rubber air seal inside that doesnt say "super sequential valve" or so i think, once i get mah car ill pulg it in n tell ya how the dupe goes =]

cheers

    • Forgot to update. I ended up removing it and found out that it's dead. The car seems to run better than it did, although I haven't driven it hard yet. Literally just a flow restriction.
    • Sounds like the rack seals blew.
    • ^ This is all good advice. I can imagine that there's some passive components in the HVAC controller that run that PWM output that could die, or suffer bad solder joints. It can be worth opening it up, taking a schmooze around looking for swollen electro caps, evidence of liquid escape anywhere, tracks that have been hot, lifted, cracked, etc. A DMM might not be suitable for seeing if the PWM output is pulsing. Might be too fast and too low voltage for a DMM to keep up. An analogue voltmeter might give a better hope. I use a handheld oscilloscope (<$100 from Aliexpress if you want something cheap). A DMM might see the voltage across the motor flicker. Otherwise, as above. If you can successfully see PWM action, then the control side should be good. If you can't see it with what you have, you might need to step up the instrumentation used, as above. Beyond that, and dbm7's advice on testing the motor directly, you're down to looking for broken wires, corroded connector pins, etc.
    • So Thanks for the comments etc. To follow up on this, we went down the path of fitting a divider down the middle of the external pipe that was added to the exhaust manifold and the divider went from very close to the external wastegate all the way up to the "V" part where the pipes from each side of the manifold joined. After this modification it was finally in a position to do the dyno-tune with some degree of success. Top end power was down about 10kw (250rwkw down to 240rwkw) I believe from previous but it seems to be more responsive lower down and at least it is now driveable and fun and back on the road to be enjoyed. Apparently the timing couldn't be run the same as it was running into knock and boost was down about 1psi. For all we know this could have been from the fuel being a bit older, or perhaps some slight complication from the new head gasket as we didn't have compression figures from before that mod to compare. I'm no mechanic and this is second hand info but I just wanted to follow-up to those that commented or read the original post with interest. After so many months of stuffing around this is a big win. The interesting part was most of the info around this was gained from information around Barra motors and not GTR as the manifold setup on the Barra with single turbo was more similar.  Thanks for those that helped with info.

    • G'day ... first up, I very much doubt that's a resistor network (as used also for this job), but the part# looks right. The description of 'power module assembly' looks to be nissanese for 'PWM driven, ground switched, DC motor speed controller'.... the circuit in the schematic kinda infers that's the case... ...with the transistor symbol appearing in the unit described here as 'Fan Control Amp(lifier)'....being driven by pin20 on the HVAC unit,  and a feedback signal on pin19 from the motor negative terminal for some reason (might be motor fault detection, maybe they detect commutator switching to determine motor revs as well, I dunno)... but if they are  counting commutator spikes, a bad segment (or really worn brushes) will throw a spanner in the works... The motor itself will as said be brushed DC with segmented commutator, rated at 12VDC nominally ~ now-a-days I just unplug them, determine the positive wire, and hook them up to a variable power supply and find out how much current they draw, if they work etc etc ...you can also check for bad segments...ie; set the power supply up to feed 1volt @ 2amp max, then watch the wattage count as you slowly rotate the fan blower motor through a complete revolution ; any bad/dead segments will be clearly evident...some folks would just say determine the positive wire, and feed it battery voltage, and if fan spin, you've got a win...<grin>... well, at least that infers it should do something when plugged back in, and the HVAC unit commands it to run... and if it doesn't, you suspect the module, but you should check the PWM signal on pin20 is actually present, and if it is, blame the module ...
