did u guys tap into the charge pipe for the IN... if so how did u do it? u think if i just drill the charge pipe, screw the fitting in and use some JB weld it would work? it says to tap the charge pipe on the greddy site but i dont know how to seal it up besides an O ring or JB weld...

or is there another way without tapping the charge pipe?

 

You can use the boost signal port on the compressor outlet if you compressor housing has one. If not its cake to drill and tap one 1/8 npt for the fitting of your choice. You can take that signal from any line that will have boost.

 

my profec b2 is just hooked up to my vacuum manifold. like the other guy said any vacuum source will work.

 

I had my Profec B drawing from my old Skunk2 Manifold, now I got a Victor X and it is also tapped off the ports on the back of it.

 

I used the port on turbo compressor housing... best source for +boost pressure to control the wastegate diaphram

 

yea my new turbontics 60-1 has that port.... will probably use it when I get up off my *** and do something
