ok so Warrtalon gave me some questions to diagnose the problem and here are the best i can do on the answers


- What MBC is it? hallman
- How EXACTLY is it hooked up? (every line, every hose, every location, everything)
It is hooked up with a T from the intake manifold and BOV to the MBC then out of the MBC to the wastegate.
- What BOV do you have? (how is it hooked up? stock intake? stock UICP?)
It is the stock BOV with a aftermarket intake(idk what kind) and stock UICP
- Take pics so we can see these details
- What boost gauge do you have? Are you sure it's accurate?
It is a autometer boost gauge that i believe is accurate becuase when its off it goes to zero
- How low can the boost go when you turn the MBC all the way down? (11psi min or lower?)
When i turn it all the way down it goes to 11PSI
- Is there a point at which it hit 17psi when turning the knob, or is this only at max? Does it hit 17psi half-way, but then doesn't go any higher if you turn it to max?
It hits 17 PSI half way and when you turn it more it doesn't go any higher.
- What hoses are being used? Have you taken the whole thing out to inspect every hose to ensure they aren't the stockers with restrictor pills?
Thats the next thing im going to do probably this week.
- Have you removed everything to double-check all the connections, hoses, and nipples? Is the wastegate actuator nipple bent? Is the turbo nipple bent? Are you even using the turbo nipple? Is the BCS capped off? Is the hose to the MAF pipe in place? If not, is the MAF pipe nipple capped?
I will also check all of this later this week and if something is wrong wiould the thing sin this question make a big difference and why?

 

welllllllllllllll

 

Although in a weird place, your connections seem to be correct. I would check on those last two things warrtalon put on there, and hopefully it will all work out. Good luck

 

Dont T into the Bov for your mbc. t into the nipple off the compressor housing to wastegate.

 

Are you using the heavy spring?

 

yes i believe so.......i might try to hook up the MBC the other way like ckjeepin said. The other question i have if i did this would what to do with with all the other lines.

 

+1

Thank you, I agree 100%, use the compressor housing as the source!!!

 

Not sure what being fat has to do with anything (have you seen some of the smartest and fastest evo owners on here?)... but fsugatorbait has got a point there. No need to start a new thread everytime you have a question about the same problem.

 

Real bad place for the Hallman. Right over the manifold is not a smart place for it.

Turn up your boost and get "H B C" branded into your skin with the 300*F controller. Move on the intake side.

Tapping into the BOV can also work, but its based on manifold pressure, not compressor pressure.

 

what does it matter if i start a new thread, it shouldn't bother anyone and i know there are some really smart guys on here that know a lot and i appreciate it.

Anyway.....if I hooked up the BOV the other way....what do i do with the connections that are already made for example the t is made from the BOV and the intake manifold?

 

On the new thread issue, if all the good info is only in a few threads then Newbies like me and you can find it easier. I don't know if you used the search function alot but it's a pain. Threads with links to other threads that have links to other threads gets old after an hour or two.

As far as what to do about your vacuum lines, I switched from the BOV line to the compressor pipe also, I just ran a new line for the BOV. Vacuum tubing is pretty cheap.

 

thanks.....i kinda understand but can you make the connections a little bit more clearer?

 

Go out to your car and disconnect the hose that runs from the butt of the Hallman into the the tee. Remove the tee completely so that the BOV is connected directly to the manifold. Take the hose from the butt of the Hallman (source) and connect it to the nipple that protrudes from the black turbo outlet pipe (your LICP connects directly to this). This is best reached from under the car. Apply zip ties to each connection to make sure none of the hoses come loose. Once this is done you can eliminate installation error as your problem.

 

thank you i appreciate it

 

ok i re-routed the mbc to that specified connection and still the same. It wont go any higher then 17 PSI.....all the hoses are after market without restrictor pills. This baffles me. I might as well just take it to a shop.
