the bov was fitted on factory cars for a reason

take it off or block it if you wish, but its doing some damage

how much i cant say, but its doing some

the service life was changed after bovs were factory fitted

so there is obviously some justification behind it

are you sure?

It was the introduction of BB around the same time?

A mates VL did close to 300,000km's with the std bush turbo running 12psi with no bov, he travelled almost 200,000km's in it.

I was talking about blocking it off, going to have a bit of fun on Friday night, then putting it back on. Its not like I'm running hectic boost, only about 7psi atm. Just wanted to know if I am going to be destroying my turbo or not.

Your Turbo will be fine :devil:

Ive gone through so many threads and read so much about not using a BOV. Conclusion is that it will not damage your turbo at all. At the most it will take 1 hour off the life time of your turbo, lol.

Block up your manifold tube and block the BOV with some metal or a coke can and listen to the fully sick flutter :devil:

this thread is a joke, to all the morons obsessed with the fluttering noise, the only real flutter that sounds any good and is the cause of something useful comes from a wastegate, preferably an external one off a big turbo. Otherwise dont bother trying to obtain the noise through other means because it never sounds the same and it never sounds cool, its merely an imitation of wastegate flutter.

:devil:

wtf...... seriously

ye i like my REAL wastegate flutter, not this fake stuff all you loosers have.

the best thing is i have 2 waste gates so i get the sound x 2.

Otherwise dont bother trying to obtain the noise through other means because it never sounds the same and it never sounds cool, its merely an imitation of wastegate flutter

Alluminium is a very good conductor of heat.

Anyway your right the coke can will work... bit dodgy though :laugh:

I can't believe this thread is still going, and that you still want your car to flutter.

My bad there. Wasn't all with it that day.

Anyway. As for worrying about aluminium melting, it has a melting point of over 600*C....

Nissan didnt use a BOV on the redtop 20's, and I know of PLENTY of people who are still running the stock turbos on 12+ psi on these engines, so, really its up to you. I dont run a BOV on my 25, and im not going to, dont listen anyone who feeds you the bullshit 'its gonna blow your turbo' story, cause it doesn't.

Edited by juddieR31

So if my RB25 is in good condition this will not blow my turbo running at 7psi boost? I am interested as both sides have put up a very convincing argument and I want to know for good what the deal is.

Both sides :P theres like one guy saying it'll blow up, and saying that his blew up the day he changed it over.. No one else has recorded anything else of the sort, and the amount of people running big turboes or stock turboes on hi-boost without BOV's shows that if theres any extra wear it's very hard to notice.. It's certainly not going to cause any short term problems

    • Hope you aren't too sore after that one, might take a day or 2 to notice yet and I guess it is a loooooong drive home. On the bright side, tube frame front end is a thing at superlap, right?

    • The chart of front pressure to rear pressure (with one being on the x axis and the other being on the y axis) is not a straight line on a typical proportioning valve. At lower pressures there is a straight line with one slope, and at higher pressures that changes to a lower slope. That creates a bend in the line at that pressure, called the knee point. If you do not change the proportionng as the pressure gets higher, you will suffer excessive pressure (at one end of the car or the other, depending on which way you look at the proportioning action) and then get lockups at that end. The HFM BM57, from my memory of previous discussions, is based on the BM57 from a different car (to a Skyline), with a different requirement for the location of the knee point and the distribution of pressure front to rear, and so is not a good choice for an upgrade on a Skyline. Here's a couple of links to some old posts, one from here, one from elsewhere. A lot of it pertains to adjustable prop valves, but the idea is the same. There are plenty of discussions on here about this issue from al the many years of people wanting a cheap/accessible option. https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/ https://grassrootsmotorsports.com/forum/grm/learn-me-brake-proportioning-valves/236880/page1/  
    • Yeah dunno why johhny posted that here with no context, just post on FB/insta bro where he put it up?  Laine had an off at T4 during Thurs prac, he's ok, car is less than perfect, they are done for the weekend, he can fill in the rest. Bando also binned it like 100m up the road.   
    • I feel there must have been a FB/insta post and the weekend did not start well at all I hope everyone is all okay
