Hey hows it going guys,

I was wondering, when seeing my mates cefiro motor it doesnt seem to have a stock blow off valve and when you change gears it flutters. Now if you look at my r32 its got a stock bov and when u change gears you can here the bov going off, no flutter.

You guys probably have your different opinions on this but its about blocking the stock bov on the r32.

Now it comes down to my question if both cars have a the RB20 does that mean, because the cefiro hasnt got a bov the stock turbo is gonna give up quicker? Cos isnt this chopping or fluttering sound bad for ur stock ceramic turbo? If it is alright for the cefiro to not have a bov would it be alright for a r32 to have its bov removed? If any one can shead some light on this area it would be much appreciated.

Didnt nissan put a stock bov on it for a reason, to protect the turbo from that back pressure then causing the flutter sound? why dont cefiros have a bov?

This has had me baffled for quite a while now, what do u guys think then?

Cheers.

ps. sorry about all the questions.

I doubt the fact you say they are classed as a "luxury" car is a warrant for not having one. If anything it would be the opposite.

Think of a typical luxury car owner and there shock when they heard the sound of flutter! They would be back at the dealer in no time saying something is wrong.

I have a HR31 GTSR, far from luxury and it has no bov from factory. None of the R31 RB20s had bovs. What years were the ceffy and laurels produced?

Maybe it was an emission thing to fit bovs later on? No BOV would have the breather gasses ( dirty oily air) venting to atmo through the filter.

      Just a thought, but instead of restricting, is it possible to do like an "up for review" kind of thing? Where say someone who's not an admin/mod tags, it would require approval for it to actually tag? User posts with a 'tag' > Admin/Mod Reviews > Approves tag > Tag now exists kinda thing? Just came across this thread so Im not too sure if Im straying off topic or not but forgive me if i am...

      Yes, a plan for non-action is always my first sort of plan! I'm happy to see what falls out of invision's update. I had been having some thoughts on what to do with this the other day and they all seem to have fled my memory, after various solar panel induced traumas, squeaking suspension sphericals, etc etc, over the last little bit. I'll try and recall what I had in mind and make sure that I put it into print in some form before the Alzheimer's strikes again.

      The ability to have both a 5500 stall for launching, and a regular lockup for every other scenario is pretty sweet. Does it actually work well like that though in the real world? Would it hold up to track use and otherwise you'd never know you had a stall converter in it? If so, that's awesome

      The thing is, once the content has been tagged we can chop and change the end result as much as we want. Its identifying the content in the first place that needs to be done regardless of the final outcome.

      Sorry @GTSBoy I thought I'd replied here. There's a new BIG version of invision coming out soon, it might be worth waiting until that happens as it contains a lot of improved functionality for tags. My suggestion would be to add a top level page (not thread) with some info on it and then link to sub pages for various topics. We could even just start really simple with 2 or 3 pages underneath it. Those pages could just have a view (like a pre configured search result) of the tags we choose to put on it. We could have some background or an intro on each of these pages. My only issue is that while admins and mods can update the existing content to contain the tags we want, new posts can have whatever tags the author wants. That said, the reason our tags are so messy is because of that, so maybe we restrict tagging to admins/mods in edits.
