Has anyone got an atmo blow off valve on their auto skyline? Many people roll eyes at the thought on an auto as atmo BOV goes off when manually changing gears as you step off the gas pedal... should this be with auto too? Gas it, step off the pedal, out comes the "vrooom choo" sound. I know many auto VLs have BOV that sound pretty good.

Sorry about the wanky topic but I just want some info from people who did have it done.

Cheers. :thumbsup:

I'm a wanker so I think I'm well placed to aswer this one :thumbsup:

The blowoff doesn't work when the gears change in an A/T, just when you step off the gas. It doesn't work because you're not required to step off the gas during gearchanges (duh!)...

So the only way for it to work is to drive 'attention whore' style and: speed up > step off > f*ckin whoosh! > every girl within earshot turns around and lifts their skirt in your direction.

I love it when 'tards in turbo cars time their gearchanges or step off the throttle as they go past alfresco cafes and the like... it makes having a blowoff valve one of the key things that makes you a MAN... well. that and a pair of testicles :)

mate...

an atuomatic turbo car differs from the manual in that it has an automatic transmission

THE ENGINE IS THE SAME

so, yes, they have a bov and it makes the same sound under the same condition that a manual does..

as rezz said, this is not during gear changes as you don't take your foot off the accelerator when changing gears, but whatever makes the manual car release the bov is the same in the auto

i hate the misconception that automatic skylines have all these differences just because they have an automatic box hooked up instead of a manual...

i want one of thse skirt raising BOV for my auto :P

Yeah so do I! And to think all this time I've been missing out on all those ladies! I've noticed the whole BOV whoosh as cars pass alfresco cafes as well, I can't think of any such cafe in Perth that I've been to where I haven't heard them. It all adds to the atmosphere of an authentic outdoor dining experience. :(

lol werd.

guy who started the topic, ive got a blitz type s one on mine ( came with the car ) makes the whole "psssccchh" deal when backing off the accelerator... like waz said... same engines, only time it wont make the noise is gear changes... obviously. the turbo etc works the same otherwise.

I have a G-Reddy Type-S on my auto R33 and paired with the HKS pod and FMIC its an aural feast when driving.. :(

I get the pssscht sound when I let of the throttle quickly and I get the sexy flutter sound when I let it off slow (real good at making people look). Along with this I have a FMIC which further amplifies the BOV noises (especially the flutter).

Yes it is very very wank but I love the noise. Just be smart and don't let it off when police are nearby.

Also atmo bovs may give you stalling dramas.

    • Yeah, it's getting like that, my daughter is coming over on Thursday to help me remove the bonnet so I can install the Carbuilders underbonnet stuff,  I might get her to give me a hand and remove the hardtop, maybe, because on really hot days the detachable hardtop helps the aircon keep the interior cool, the heat just punches straight through to rag top I also don't have enough hair for the "wind in the hair" experience, so there is that....LOL
    • Could be falling edge/rising edge is set wrong. Are you getting sync errors?
    • On BMWs what I do because I'm more confident that I can't instantly crush the pinch welds and do thousands of USD in chassis damage is use a set of rubber jacking pads designed to protect the chassis/plastic adapter and raise a corner of the car, place the aforementioned 2x12 inch wooden planks under a tire, drop the car, then this normally gives me enough clearance to get to the front central jack point. If you don't need it to be a ramp it only needs to be 1-1.5 feet long. On my R33 I do not trust the pinch welds to tolerate any of this so I drive up on the ramps. Before then when I had to get a new floor jack that no longer cleared the front lip I removed it to get enough clearance to put the jack under it. Once you're on the ramps once you simply never let the car down to the ground. It lives on the ramps or on jack stands.
    • Nah. You need 2x taps for anything that you cannot pass the tap all the way through. And even then, there's a point in response to the above which I will come back to. The 2x taps are 1x tapered for starting, and 1x plug tap for working to the bottom of blind holes. That block's port is effectively a blind hole from the perspective of the tap. The tapered tap/tapered thread response. You don't ever leave a female hole tapered. They are supposed to be parallel, hence the wide section of a tapered tap being parallel, the existince of plug taps, etc. The male is tapered so that it will eventually get too fat for the female thread, and yes, there is some risk if the tapped length of the female hole doesn't offer enough threads, that it will not lock up very nicely. But you can always buzz off the extra length on the male thread, and the tape is very good at adding bulk to the joint.
    • Nice....looking forward to that update
