I think Turkey is good......

think about this logically. since 505zoom eliminated the sound, that means its NOT a characteristic of the turbo...otherwise, it would make that sound no matter what you do to the piping/valves.

the only thing i can see it being is surge. it has to be, what else is it then?

Like I said, the other thing it could be is the sound of a working BPV. My 87 TC doesn't have a bpv, and it doesn't make that sound at all. No noise whatsoever when I lift my foot off the accelerator at max boost.

Now, someone explain to me why I don't get compressor surge on that car. Any why don't the Mustang SVO's and Thunderbird TC's have compressor surge?

And if compressor surge sounds like a turkey, I don't have compressor surge. The noise my car makes, in no way sounds like a turkey.

I'm curious do your other cars have plastic pipes or hard pipes?

On my 89 Mustang turbo, I have a combo of rubber and metal piping. I use a Front Mount IC from a Volvo 740, same one I pulled the bpv out of. I also use much of the piping from that car.

On the Thunderbird, there is very little piping at all. The IC sits right on top of the turbo, and have an air inlet on the hood that forces air across the IC when driving (simular to the wrx). The outlet from the IC goes right to the TB. There is maybe a total of 6" of piping, and it's pretty heavy duty. The SVO Mustang is basically the same thing. Like I said, neither of those two cars came with BPVs from the factory.

Hmmmmm?

Exactly. Why don't the SVO and TC have massive compressor surge? There is ZERO pressure relief between shifts, and they are running about 14psi from the factory.

I'm thinking more cautious engineering. Less pipe for air to get jammed in and have to work it's way way back downstream. More cautious is wrong. More like design with more potential. lol.
