The flutter sound

[GunMetalR33]

I just blocked of my standard BOV to get that Flutter sound. It works great apart from some back fires :-} Is this going to F8ck my turbo?

[drunkenmaster]

I'd lean towards "Yes, eventually"

[R31Nismoid]

agreed. Eventually.

You'll also notice your car might stall 'for no reason' at times depending on your driving style.

This is due to blocking the BOV.

The BOV is probably one of the only stock things that serves a half decent purpose (read: then I/C is crap as well as the stock turbo and the ECU to boot) I'd leave un-blocked.

[letemlaf]

my car has 2 bov's

standard (which is still running) and a hks

i get the flutter sound, its quiet loud but now anywhere near as loud as some. will this kill my turbo too?

[greddy_monstor]

I've blocked my standard off as well, but I dont get the flutter noise. Does that mean my aftermarket one is doing its job properly. Or is it still eventually gonna screw my turbo?

[croat]

Yeh u aftermarket one is fine. your turbo is safe...

[vendetta]

your gonna notice if yur getting back fire that you are most likely chewing petrol, and yes it will affect you turbo, there are a lot of threads covering this, look them up.. theres a lot of mixed reviews, bootom line is ur std bov was put there for a reason. i know of a guy doing this to his pulsar et turbo, then his engine blew.

its your risk at the end of the day

[sweetr33]

Vl turbos dont come out with a bov, although i agree that they are there for a reason, i have had mine disconnected for along time now and no noticeable damage. Still goes alrite, um...at the end of the day if u want the noise without spending money on a ssq bov etc then it shte cheaper way out initially, maybe not in the long run.

[snake]

ET turbos dont have bovs factory either.

[vendetta]

um sorry but they do

[GiJOr33]

my old pulsar exa didn't have a bov stock, and that's the same engine as the ET.

straight from the turbo to the throttle body, no I/C

[vendetta]

i had two ets. both were pretty worked. when you installed the aftermarket (bosch) bov we had to block the stock bov. which we did by unscrewing the bov off and blocking it with a large type of screw that fitted in place. trust me man. maybe the previous owner took your stocky off???

its good to see a fellow n12 owner though, i had heaps of fun in those little things, my fiorst car when i was 15

[GiJOr33]

Possibly... but the pipe from the turbo to the inlet looked factory. It was the start of my car hobby so wasn't as switched on about the ins and outs of turbo cars as i am now. But i never saw anything that looked like a bov. Mine was a 1984 model... perhaps they put them on the later models.

[vendetta]

both of mine were 84 model, factory bov. my friend had an exa and i fitted a bov on it he had the same thing too.

p.s. sorry for changing the subjest of the thread

[GiJOr33]

so his exa didn't have a bov either? interesting that nissan would put a bov on the ET but not the exa...

as for the flutter sound, i would be a little warey about trying to get it. It slows your turbo down so it has to build boost again after the gear change. Especially bad with a bigger turbo so perhaps not so much of an issue with the stock one.

[sky^rkt]

my bov has been blocked since i got the engine installed a while ago. have had no problems, not chewin threw petrol, no backfires, car doesnt stall or anything, people have had different experiences, but yes it will reduce ur turbo life. its up to personal choice

[GunMetalR33]

Is a HKS SSq and plum back BOV?

[drunkenmaster]

It must be just me but I am not building a performance car just to make funny sounds?

As above, personal choice I suppose.

[Jimbo2000]

if you want the flutter noise without riesking silly backyard blockoffs, buy a ssqv

Is a HKS SSq and plum back BOV?

yes there is a addon you can buy to make it plumback

[R33_BO]

Hey I know this may sound like a stupid question.....but what's a BOV??? I have that flutter sound in my R33 and i certainly don't want to replace my turbo just yet...so i was thinking that i might want to check this BOV to see if it is blocked by anything?
