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.

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.

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 :rolleyes:

 

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.

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.

the way they had the ball and spring positioned it would have increased boost pressure before it was regulated by the bleed valve.
