Hello
I sold my hallman mbc and my aem tru boost won't be here for a few days. Can I couple or plug the lines that go to the mbc just to get around for a few days? What would the effects be?
Thanks

 

You will run the regular (stock) wastegate pressure I believe, around 11-12psi.

 

By putting plugs in them or coupling them together?

 

I think it's if you run a line from the wastegate nipple to the compressor housing nipple. I think I'm right, because if you think about how a boost controller works, all it does is delay the boost signal through this line leading from the compressor to the wastegate, making your car think that it has not reached enough boost to open the wastegate. This would be like the job of the restrictor pill in the stock vaccum line leading to the solenoid. So the solenoid should probably be capped(plugged), the same way as if you were using a boost controller. This would get you around for a few days on low boost. I hope this helps.

 

if you run a line from the compressor nipple to wastegate nipple you will run wastegate boost

 

the 2 hoses you have going from the boost controller orignally (1 going to waste gate, 1 going to the turbo) have those 2 put together with those little adaptor things. Youll run 11-12 PSI Max because that there is an 11-12 PSI spring inside the waste gate.
