Stock Bov With Flutter

[Shadex]

Hey all, i was just wondering what people opinions are blocking off the vacum hose on the stock bov to get flutter..

I did it cause the i like the sound of the flutter =] and i dont wanna get defected for a bov, but i still wanna keep it half safe with the bov opening up after high revs...

But i dont know to much about it ive spoken to some people about it on NS and they said its fine to do. Id just like to go over it with some people that own skylines not silvias haha.

before anyone starts dissing this flamin mongrel i rkn his asking a legit question....so i hope mods give out warns accordingly.

to answer your question, unfortunately you cant adjust what level the bov will open with the factory setup. if you want that lesure u need to get a aftermarket BOV. but then it wont flutter as loudly, and like u said can get defects. if you get a legal aftermarket BOV, you wont get flutter because it redirecting the air back into your intake.

if your cars mostly factory then its fine to just block off your current bov with some aluminum casing from coke cans or something. just got out wat you need and put it inbetween your bov and your throttle body.

heres also a old pic of my engine when i put my 1st bov on. i know its not factory but its the same shit. hope it makes some sense.

personaly on my car ive notice it to be a bit more responsive when blocking my bov off because i always suspected the factory bov to leak under high boost. so this is a great way to fix it

on the other hand.......

alot of people on here will tell you its bad for your turbo, its bad for ur engine this and that. unfortuantely there isnt any proof that its real. theres 8second cars out there running no BOV at all, and are yet to even have the smallest engine problem. but some ppl do and they blame it on blocking there bov.....

my advice is.......its a good way not to get dicked by the cops, and have at least some sort of decent noise when backing off. i dont care wat anyone says its 10x better then the lame "woosh" that factory BOVs have.

alot of ppl here really have a anti-flutter attitude and i guess u gotta expect it if ur gonna follow this path.

if u need more in detail let me know.

a VERY decent adjustable replacement BOV/Bypass valve is the product offered by Turbo XS, they do a direct bolt-on replacement with adjustable spring tension, etc and it's also rated up to 32PSI before it's "suspected" to leak.

I will be swapping to this product shortly from the stock GTR bypass valve, have seen this product used on the Mazda MPS vehicles, and it makes a massive difference over their plastic valve setups, not sure how it will go on the R32 Skyline, but they offer a direct true bolt-on replacement.

This is a highly recommended modification to the standard turbocharger recirculation system. It will not void any warranty or factory backed warranty agreements. This modification is likely to increase the life of the turbocharger and coincidently circumvents the many many hours of research and development that was undertaken to increase turbocharger life expectancy. After the mid 80s turbocharger life expectancy was around 50,000 kms, after research and development, the factory recirculation system was developed, but its recommend that you circumvent this system to provide 1980 style life expectancy of the factory turbocharger system. All of the high performance work shops recommend this modification to increase street cred, horsepower, torque on the dyno and your custom user rating in points.

All your desires will be answered about how the BOV actually works (and, removing the VAC line simply wont)
