Which way to face MBC?
 

I have this thing
http://www.vividracing.com/catalog/p...oducts_id/1987
And I asked the vividracing guys, and they said theres an arrow and that should ponit towards the WG I tink.
But
There is no arrow.
Does anyone know which way this would face?
Did a search and only found the ones with the Tee.

loosen it fully and then blow into it. whichever direction you can blow through is the direction of the airflow.

it looks like the red side will be the wastegate side.

does the airflow go from the wg to the turbo, or the turbo to the wg?
Also, the mbc isnt on yet, but it looks like I wont need it becuase I cant really go any higher then 7-8ish, because im scared of blowing my motor again...I read that installing a mbc improves spool, would this work if i put it all the way on Negative so my boost stays the same? Worth it?

Flow should go from the nipple on the compressor housing to the WG - you want it to "block" flow until a certain pressure is generated, then release to allow the wastegate actuator to open.

Even if you set the MBC so that you stay at 8psi, you'll still see benefits - your spool should improve, as the wastegate will not open prematurely.

Cheers!

the easiest way to blow a motor isnt really the amount of boost, it's how bad you tuned it....IE, not enough fuel, too much spark advance.

even with the MBC at 7psi, you'll have better spool charateristics.
