vagen Posted September 14, 2009 Share Posted September 14, 2009 I just received a MBC bought on Ebay and I am a bit confused there is a "T" fitting with a ball and spring in it and an adjustable bleed valve. My question is if this is a bleed off type controller why is there a check valve? I am thinking about removing the check valve and just treat it as a bleed valve.

TheSubaruJunkie Posted September 14, 2009 Share Posted September 14, 2009 Read up on how MBC's work, then you will realize just how simple they are to install. Link to comment Share on other sites More sharing options...
vagen Posted September 14, 2009 Author Share Posted September 14, 2009 (edited) I think I have the install down but the t fitting having a check ball confuses me. I guess I had a misplaced idea that this was a spring valve controller instead of a bleed controller. I'm used to seeing the spring valve controllers.

TheSubaruJunkie Posted September 14, 2009 Share Posted September 14, 2009 Gotchya. Hope you didnt get one of those $4 home-built MBC's off ebay. I got one of those thinking it would save me a few bucks and it almost blew up my EA82T when it failed. I ended up spending $60 on a GFB MBC and it worked great.

vagen Posted September 14, 2009 Author Share Posted September 14, 2009 this looks like a decent quality piece but having a check ball in the TEE fitting confuses me. I think I'll just remove the check ball and spring and use it like every other bleed type I've looked at today. Link to comment Share on other sites More sharing options...

TheSubaruJunkie Posted September 14, 2009 Share Posted September 14, 2009 Ahhhh... yeah. When i had my Turbo legacy, there was a guy over on the Legacy Central board who bought that setup. he couldnt figure it out, but got alot of help from other members. pix & discussion can be found here: http://bbs.legacycentral.org/viewtopic.php?t=35205&highlight=boost+controller Link to comment Share on other sites More sharing options...
vagen Posted September 14, 2009 Author Share Posted September 14, 2009 thanks guys I will go with the straight bleed setup and no check valve Link to comment Share on other sites More sharing options...
TheSubaruJunkie Posted September 14, 2009 Share Posted September 14, 2009 From what I read, that is not the way that MBC works, and unless you use the T it will not work propperly. Read through the thread I linked you. It sheds more light on the subject. Link to comment Share on other sites More sharing options...
vagen Posted September 14, 2009 Author Share Posted September 14, 2009 I plan to use the Tee but not the spring and ball in the tee. Link to comment Share on other sites More sharing options...
Turbone Posted September 14, 2009 Share Posted September 14, 2009 (edited) I plan to use the Tee but not the spring and ball in the tee. You might end up overboosting. Then you can kiss that EA82T byebye. Ask me how I know Actually, if you have a boost gauge, try it without the TEE completely. If you dont get boost creep, it might be ok without it. But I would use any MBC without keeping a sharp eye on the gauge. Edited September 14, 2009 by Turbone Link to comment Share on other sites More sharing options...
vagen Posted September 14, 2009 Author Share Posted September 14, 2009 I have a gauge and I will be watching this like a hawk. I will not add any boost till I have the intercooler installed. The plan is to intercool and then add boost. I am planning to add an egt and a WBO2 to further monitor things. Link to comment Share on other sites More sharing options...

Turbone Posted September 14, 2009 Share Posted September 14, 2009 I dont know why they added that tee with the kit, unless its supposed to have the boost gauge connected to it. But I dont understand why the ball&spring for it. Link to comment Share on other sites More sharing options...

TheSubaruJunkie Posted September 15, 2009 Share Posted September 15, 2009 The guys on the other forum refer to it as a "Bleed Type Valve" Im not sure, its not the type of valve I have used. When I bought mine, I did my research ahead of time and bought the correct valve that worked right the first time Link to comment Share on other sites More sharing options...

vagen Posted September 15, 2009 Author Share Posted September 15, 2009 I did some research on factory boost controls and what I found was a bleed system operated by a solenoid valve. I will try this unit and see if it works if it doesn't I'll buy a spring valve type. Link to comment Share on other sites More sharing options...
