Installing Bleed Valve With Hybrid Fmic?

[bernard R33]

as topic state i have a hybrid fmic and about to install bleed valve. there is no hose going into the intercooler piping. did a search and ppl say they drilled a nipple into there intercooler piping. dont really want to do this. there must be a way to hook it up. any one done this b4? got any pics?

Theres a vac line coming from the throttle body down and under your intake pipe where your bov sits going to your carbon canistor, put a 3 way thingo (cant remember wtf they're called) and then go to your bleed valve there... or use the search button..

actually you need to make one up, do not put vacume to the wastgate, as the diaphram is not designed to work under vacume, it will get damaged. Best thing to do is to drill and tap the stock cast intake pipe, BEFORE the TB and put a screw in nipple into it. That is how i did mine, works well.

Hint: you can use a one way valve when tapping into the BOV or manifold pressure line, this will eliminate the vacuum issue.

A nipple on the pipe would still have vacum?? woudlnt it?

Um... this doesn't make sense about the vacuume to the wastegate damaging the diaphram... doesn't the wastegate open and close on vacuume/boost pressure, isn't it designed like that from factory? And if you are right why does everyone that i've seen just run it from the vac hose, to the boost controller to the wastegate?

[bernard R33]

the hose that is supposed to go onto the intercooler piping is t-pieced into a hose that runs to where the intercooler pipe joins to the intake plenum if that makes sence. can i just join the bleed valve to that line. if that doesnt make sence ill get a pic later.

[WogsRus]

no as soon as boost pressure is released the spring forces the gate shut, there is no vacume on the setup, as the stock boost tap is placed before the TB. Introducing vacume to the diaphram can couse the diaphram to pull away from the shaft mounting plate thing, sorry can't remember the techincal name. If you do use a one way valve, ensure that it is placed before the tee peece bleed valve, otherwise you will get boost goign to the gate, and then it will stay open as it will still be under pressure.

Ahh i understand what your saying wogsrus, but does it really effect a good wastegate actuator or just standard? or whats the deal? mythbusters time....

[bernard R33]

the yellow line is the one that is supposed to be connected to the intercooler piping. if i put the bleed valve between the yellow line and the actuator i still dont see how it wont work because the standard boost control is hooked in there and why would the mechanic hook it up like that if its wrong.

As long as that hose has vacume pressure its the right one. Or am i wrong?

[bernard R33]

tried installin bleed valve how the lines are now and i had endless boost so yeah didnt work. any other suggestions or will i just have to get a nipple fitted to the intercooler piping?

[Gazee]

dude just take it back to your mechanic and tell him to sort it for you before something bad happens
