Boost solenoid 1 or 2?

[AJP turbo]

Does the SHO have 2 boost control solenoids or 1?....I was out logging tonight and I heard a little pop followed by some hissing and overboosting immediately....Got out and went right to the solenoid on top of the intake manifold.....The one little hose popped off like what's happened to other members here...You know the hose that has no clamp.

Under the charge pipe that goes over the engine there are 2 vac hoses that I presume come from each turbo...I didn't have time to poke around in the dark but does anyone have pics of the hoses that come out of the turbos....On most turbos Ive messed with there are vac hoses(boost reference) that come from the compressor cover...I haven't really seen the compressor covers in the SHO..

I hear a little hissing still but I think it's the check valves by the brake booster but I wanted to know if there is another boost solenoid buried down deeper that has one of those hoses that may have blown off

I can definitely get you some pics,but!!   and Info.  Z

LOL, Z!  I see only one bypass solenoid listed on the parts diagram (BL3Z-9K378-A).  This is the video you are referring to, AJP?

Well Z I do love your insight and technical data.....But love you? Nah, you are too ugly for me lol

Actually I thought about it and tell me if I'm right.....I don't think there are vac hoses coming out of the compressor cover.....There is only 1 boost solenoid I think and it gets the boost signal from the vac hose that comes from the charge pipe and the vac hose that comes out of the boost solenoid goes to a TEE and to the wastegate canister on each turbo.

It's actually really dangerous that ford didn't clamp that. That is the reference that needs to go to the canister to open the wastegate so you don't overboost.....You could run the reference line from the charge pipe and to the wastegate on each turbo and that would give you base spring pressure for boost

The reference goes to the solenoid and when you run higher wastegate duty cycle it's bleeding out more of the air so less goes to the wastegate canister and keeps the gate shut, raising boost.

I wonder if Ford addressed the issue of the wastegate hose popping off on the 15+SHO' model's !!!Definitely agree its a problematic issue even under stock conditions and should be corrected and will try to provide you with some technical data & Diagrams by tomorrow concerning the above matter from one of my reliable sources,were you able to verify the root cause of the issue yet? personally installed 11-13 mm clamps on all the hoses.  Z   

[AJP turbo]

The root cause was 20 psi lol....so only 1 boost solenoid?

I believe it is one solenoid controlling the lines to both wastgates.

Thank you....wonder if the vacuum hoses that come from the solenoid that go to the canisters on the wastegate actuators have clamps?

Negative on the clamps on other end. At least on my 10 they dont.

You can see them?

[tgambob]

Not without camera assistance. Was checking out my leaky turbo so went all over it. Those cheap boroscopes work great for all kinds of things. Especially tight engine bays or ones with very heavy cabs over top of them lol

[tgambob]

Are they supposed to have clamps? My 10 is decently early so I do have some goofy things going on.

[AJP turbo]

The wastegate canisters do not have clamps....i just looked and didnt need a boroscope....kind of tricky. They appear to be stuck on good...that one on top is problematic because its a plastic nipple and will usually have oil...i clamped it and wastegate hoses are on so im ready to rip now

[SHOdded]

Ooooookay ... hopefully the next update will report positive results from this experiment

Here is a Diagram i was able to obtain,have a few more for later viewing.  Z    https://drive.google.com/file/d/0B8JUL90DXgdiTTdiSzJhWkkwM0JfYXY5RmVySF8waEtENHZN/view
