Intake Flutter

[maverick_990]

I have looked all over and I could not find an answer, so if someone finds one forgive me, but I put on an intake on my 99 GST and when I shift gears I here a flutter coming out of the filter, I am to understand this is Compressor Surge, but how do I correct it??

My BOV isnt recirculated, could that be the problem??

Or if I take my intake back off and put the stock box, will that help?????

Or is it STRICTLY just the blow off valve?????

do you have the proper mods for having a VTA blow off valve. what bov are you using did you set the spring stiffness yourself? It could be compressor surge. I would def recirc that thing.

I bought the car about 2 weeks ago and I believe it is just a knockoff type rs and I dont know how it is set

There's a little nut on top of the BOV. It may say Hard/Soft. That's what you want to adjust. I believe you would want to go soft because the BOV is set too hard and not venting quick enough (correct me if wrong).

You probably had compressor surge the whole time, but the hard pipes for the intake just make it more obvious.

[steviek]

yea you're gonna need softer (if the bov is even functioning properly)

I went softer and it still does it, I think I am going to have to get a new BOV....
What would be a good one that doesnt cost too much?? I would put the stock one on for now but I dont have it

Get a 1G BOV. Can find them on eBay for like $30. Can get some high end ones, like Tials and Greddys, but expect on paying over $200 for them.

[maverick_990]

ok thanks, why a 1g instead of 2g?

[steviek]

1g's were metal and the 2g's were cheap plastic the 2g's leak at a much lower boost presure then the 1g's ever would.

[maverick_990]

oh ok

Is there anything tee'd into the BOV reference line?

[maverick_990]

No the hose going from the BOV is not tee'ed..
This is an older pic, I have an intake on it now...
and the guy I bought it from put a FAKE greddy type rs

[steviek]

If you want I can have a look in my garage for the stock 2g bov I have lying around Ill send it to you if you want to pay for shipping.

[maverick_990]

will the 2g be better than this knockoff?

I have a crushed 1G bov that I will sell for $20 shipped if you want it?
