aight, just upgraded too a external wg. it's a tial 35mm. I'm not sure which one too use for the vacume source, or do i hook both of em' up? i hope that's enough info for you guys. But it came with only one threaded nipple, is it either i put the nipple on bottom or top.

 

use the nipple on the side, leave the top one open...

 

I was kinda asking a similar question and still no responce but here is what i have read that i belive is true. The top port is for the vac source if your using a VBC. I believe the side port is for boost side if you wanted to hook it up that way in my case this is what im trying to find out for sure. Im not sure on this info since it came off the web and im trying to get some feedback in my post in this forum from earlier today.

 

aight..i see, but sorry if i described it correctly, but the two nipples are on the side of wg one on top and another underneath it parrellel..so i guess i'm gonna use the bottom one then. I'll see how it will boost.

 

i remember back in the days of the deltagate if you hooked up the top nipple then the car would not stop boosting

 

top nipple is for boost conrtol one on the side need to be hooked up to vaccum
