[TYWRAP]

Keller,

The nipple on the WG that has the pressure source from the turbo running to it is where you T into. (I'm guessing though, no experience wiht the hallman).

I run mine between the pressure line from the turbo to the WG.



Boost source--------------MBC-------------WG

The other line from the WG I leave open to the atmosphere.

HTH
