Air intake - how do I get turbo flutter?

[OVR444]

I have a mate who blanked his BOV off with his licence. I thought that was a good effort.

that would be the first time it would have been used in a constructive way... the only time mine every sees the light of day is either buying alcohol or being pulled over for a license check. In saying that I have had the legnum for nearly 1 year and haven't been pulled over once... vs my old wrx where it was a daily occurrence...

Anyway.. back on topic..

How fantastic does this sound....

Does anyone on here run a Greddy Type RS? or even a Tial 50mm? I love that note they make when venting... not just the woosh.. kind of like the sound of a internal gate on a big HP jap car; my old GT35R used to make it!

First one sounds like flutter to me, the guy probably has it set to hard or isnt hitting full boost. Sounds cool but

in my old s13 I for sometime ran no bov, then was given one so stuck it on, as an interesting point with no bov even on low to bugger all boost ie when the car was still spooling up I would get big flutter (had stainless intake etc which helped) yet on high it would make no noise or flutter or fart or anything, just sweet spool sound then gear change and more sweet spool sound, put the bov on and of course pfffttt! on boost, did it make a diff? not in my opinion, nothing noticeable anyway, the turbo was ran for approx 60k's without bov and was stripped down b4 new manifold went on and turbo was AOK... make up your own mind in the end, I think half of it is marketing BS to get us to buy bovs, at the end of the day the littel turbo's we run on vr4's are not exactly designed to run 30psi are they.... i dare say the small amount of boost they produce would not harm the turbo's without a bov, factory or otherwise.

Agreed, without a doubt its compressor surge and a bov wound WAY to hard.... to me thats one of those relative "turbo" noises... as soon as I hear that I think of jap street racers

ive tried to take a voice recording on my phone, but it just sounds like static.

Well i have a friend who really wants me to bring the flutter back so ill probably put it back for a bit and when i do ill try record it with my mrs new video recorder. Ill try show the boost gauge too when i do cos it literally drops from say ten to seven psi and your straight back on boost.

 

[unclepaulie]

yo steve, what did you do about the vaccum line? block it off?

 

[steveP]

screwed it, literally.

 

[mills_88]

+1 for screwed it, best way

My car came with hard pipes, FMIC, pod filter with hot air induction and blow off valve removed. Yes it sounds like whoosh (like sneezing) all the time. I don't find the whoosh as satisfying as the flutter or violent BOV sound of my modded Lancer wagon. I'm going to have to wait till after the wedding to fork out an SSQV or something. I'm also thinking about sending my GFB Stealth which blew up on me back, and if they have some decency, give me a replacement new one! A BOV isn't rocket science, I can't believe mine blew apart! LAME.

i just put my ssqv to plumb back today. good decision imo

Gay.... How you supposed to scare the shit out of cyclists now?

Thats what bumpers and folding mirrors are for...

 

[steveP]

no, thats what external wastegates are for.. mahaha!

 

[unclepaulie]

i know dawso i know, but the car drives a bit different now so that good.

its only 3 hoseclams and im back scaring pedestrians all day.


offtopic, off what steve said, anyone looked into split dumps? that merge back in later?

 

[pu-11-me]

Ah well, as long as you're happy man!

 

[ygoslo]

I'm thinking about fitting my spare ARC bov when I go hard pipes. Just for poos and laughies.

 

[mills_88]

Well i took my bov off again today so me and my mate could record it tommorrow. On the way home from work it blew what i was using to blank off the bov clean off leaving me to fix the problem by the side of the road. So i dont think ill be able to help with video as not only do i no longer have the parts required to block it off properly but i dont want it popping off again. Decided i prefer the noise the stock bov makes with a pod anyway.
