compressor surge?

[Nick2gGST]

So in my case, I recirculated the bov setup using a 1g bov supplied by fabian, thanks mang. Had to buy a longer vacuum hose (might not be stiff enough) for the top of the bov to the IM... sooo now, when I start my car it always flutters at almost any rpm above like 1.5 i hear tstststsss, sooo I opened the hood with the car running listened, I could hear it mostly from the k&n filter. So my first step was to un-circulate the bov and listen directly to that to see if the tstststs was just flutter...but nope, i revved it up again and it was still coming from the k&n filter...I'm sure with the air coming back through the filter the wrong way (if that's what it's doing) it's probably not good for my stock mafs. My only few thoughts are...
1. bov is too stiff? it is crushed.
2. the vaccum line from the nipple of the bov to the IM is not stiff enough so it may be collapsing?

I'm not sure if my vented bov made this sound or not because the bov itself fluttered too.

If it is my turbo itself, why would it do that? If I replace the turbo can I replace it with a 16g without any mods? just literally bolt on the turbo itself and go?

all the bov's I have and am getting have an adapter I guess because they have a tube on the bottom that fits in the hole on the intake tube that clamps. I see you do have a lot of posts, reading the whole situation is part of it if you wanna help someone out. Just like a lot of us get yelled at to search, it's just part of the forum thing. But yeah The base of the bov's are like a diamond shape that have two bolts, BUT they both come bolted to an adapter I suppose and the bottom of that fits in the place of the 2g hole.

So, with this tube, if I understand it right. It sticks down into the hole on the UICP, thus restricting airflow, and possibly not even allowing boost pressure to reach the valve.

Do you have or know someone who owns a camera? Please take some.

[Nick2gGST]

95fwd no...it's a thing that comes out of the intake tube have you guys not seen a stock 2g intake tube? It's that.

 

[VETTE_50_TH]

Ok. So you must have an adapter on it. You wont be able to do that for the greddy one.

James

 

[Nick2gGST]

the greddy one does

 

[Nick2gGST]

Fabian can you please post pics and let these guys know what the hell I'm talking about?

It's in his gallery ffs!

That's a stock UICP for a 2g, with the recirc tube blocked off.

Now show me a picture of how it is now!

1g BOV flange (ignore all the captions)

@rob that does clear up some of what is going on but how in the hell is the 1g bov connecting then?

 

[Rob10_99]

I think he's got one of those billet adapters or maby something ghetto?

Maby it's hooked up backwards? ....

 

[VETTE_50_TH]

Dont laugh. He might.

James

 

[the_mork]

It was a thought that crossed my mind when I was looking for pictures of the base but I didn't want to sound like a prick for suggesting it.

For the record if you hook it up backwards it will not work with a crushed spring. Interestingly enough it should work if you've changed the boost reference and the spring is uncrushed as I've seen on a couple occasions with a 2g bov which makes it hold air much better. That requires some planning and knowledge though so if you haven't purposely done it then it wont work.

95fwd no...it's a thing that comes out of the intake tube have you guys not seen a stock 2g intake tube? It's that.

are you talking about the dump tube inside the intake after the mas n before the turbo?

OP are you confused because your bov shown in this pic is connected to the uicp using the recuirc tube instead of a proper adaptor or flange? your posts are getting confusing because you are asking questions about bov flanges then talking about the intake having a tube wich really has nothing to do with bov, all the dump tube does is direct the air right onto the compressor

 

[the_mork]

FWIW this is how a 1g bov should look on a 2g.

mork theres an adapter on that bov tht plugs right into the spot on the tube thats connected to the recirc tube in my picture above. it'll fit i promise.

 

[Nick2gGST]

mork that is what mine looks like now! thank you! my bov isnt that shiney and mine is much more crusedh but...

 

[sarge281]

Hey, Mork, I got a ? for ya. In the pic that you provided, the tube that runs from the 1G BOV recirc. fitting to the intake recirc. fitting...is that a stock 2G tube? From that pic, it looks like a hard, cast plastic pipe. See, I bought my Talon used, and the previous owner (obviously an asshat) swapped the stock BOV for an APexi...(amongst other things)..I ddn't get that recirc. pipe. Think I might be able to get that from a dealer? Or a pick n pull lot, maybe.... Thanks, man!

 

[Rob10_99]

Not a dealer part by far. You are more likely to find that on bay or the classifieds right here. Tons of people upgrading to FMIC's and even have them in their garages, maby post a WTB ad?

Ok so you have a 1g flange, that UICP looks shiny so I would say its PC'd aluminum or steel. Saying that, does your SMIC look like its new or bigger than usual?

 

[Nick2gGST]

Dear thread jacker,
Are you talking about the recirc tube? Turns out I do have an extra one. I didn't know the one my blue rfl was on was actually for the recirc.

 

[sarge281]

Wow.
Uh, ok, sorry I jacked your thread. Yes, that's appears to be the tube I asked about...don't know for sure, since you don't have any pics listed in this thread.
And, about the thread jacking thing, this thread's been rolling for 3 pages now...you've gotten plenty of good advice from people here. There was a lull here, thought I would ask. People on message boards and the internet as a whole need to freaking relax...I meant no harm.

 

[Nick2gGST]

chill sarge i was playing , I'll send it to you if you ship me a few bucks for shipping and whatever the tube is worth to you ### im broke no money to even ship .

MORK, my bov is hooked up exactly the way in that last picture you posted EXCEPT my vacuum line runs to my intake manifold, i don't have a MBC or anything.

 

[Nick2gGST]

Also dert my OLD bov that you see in that picture came with the car, i didnt set it up that way, but it was done that way because it was too tall to stand up on the intake tube itself, I wouldn't have been able to close my hood.

 

[the_mork]

Does the pipe look like that too or is it a crunched up piece of shitty plastic? I guess this discussion is probably near complete and you are saying that you have a 1g adapter with the 1g bov. Fine. What you should know though is that the 1g bov and the greddy bov have different flanges. It may or may not be possible to drill the adapter to match the greddy. It will in no way be a bolt on affair.
