I just bought a hallman mbc from a forum member. On the nipple going to the wastegate actuator there is a small hole that the vacuume line will not cover. Should this be there? Just want to know before i install it. Thanks for the quick replies!

 

If you are talking about a 1/32th inch hole, I have it as well on my forge Unos. It's normal

 

Its even smaller, a paper clip MIGHT fit in it.

 

am i blind or did you say 1/8th inch first and then change it . Yea its like 1/32nds

 

I'm busted I'm not American so I have issue with units conversion
So yes it's very small, you could barely fit a paperclip

BTW, is the hole on the nipple or on the MBC? mine is on the MBC.

 

its on the hex of the nipple, where tou would use a wrench to take the nipple off the mbc. Thanks man
