HELP: Evo 9, no boost, loud whistle, hanging hose
Awhile ago, while under boost, there was a loud pop. Since then, anytime when accelerating and I should be building boost, all I get is a loud whistling sounds. If I were to continue accelerating, the computer gets mad, presumably cuts fuel, and kicks the "service engine soon" light on. After a few days of no boost, then "service engine soon" light goes off.
Today, I jacked it up, took off all plastic crap covering everything and I see a small hose danging. May be related, not sure. That's where you guys come in.
It has a Buscher inter-cooler and upper pipe on it after a front end accident. When the bodyshop put it in, they contacted Buschur and ended up doing something with a t-adapter since I think a hose connects to some nipple on the pipe. It's been several years and my memory is a bit fuzzy on it.
I took some pictures of what's going on under there: https://imgur.com/a/6cjfo
Thoughts?

stock boost controller:
one line goes from the turbine housing to the t-fitting
one line goes from the wastegate to the t-fitting
the t-fitting goes to one port on the boost controller
the other line goes from the boost controller to the intake piping
one line goes from the turbine housing to the t-fitting

the t-fitting goes to one port on the boost controller

So it looks like from my pictures that I got one going to the wastegate, and one to the boost controller. I guess I just couldn't see the connector on the turbine housing.
Thx

However, as pointed out by Kaj, above, there is a port on the j-pipe (aka compressor discharge pipe) that sources manifold boost pressure/vacuum. One of the 3 hose ends on the vacuum/boost hose assembly should be connected to that port.

I agree with you, Kaj. I too am positive that Demon meant to write, comp housing, and not turbine housing. I just couldn't resist the chance to take a free pot shot at a mod. No harm intended though

I imagine that no one consciously makes incorrect assertions on this forum. In the 1st place we are all on here to learn about Evos. To unwittingly make an incorrect statement just happens sometimes. Mistakes are a human failing, right?
No hard feelings.

I had this coming and it goes with the territory. I took a potshot at Demon but with no ill intent. If I wanna dish it out I better be ready to take it.
