If you dont need it for BAC, go for it. I ditched my BAC with my ported motor, and removed the nipples from the block and water pump, and tapped the holes. Then I lock-tite'd a set screw in there. Worked great.
If you dont need the BAC, you dont need that line. But if you do that, make sure you block off both of the nipples, water pump and rear end plate.

that line has nothing to do with the bac. the only reason I see the line there is to stop the BAC from freezing?? but no coolant goes into the bac. the line can be removed with no effects to the BAC.
so yes once you do the TB mod you remove that line as it has no purpose after. as well as the other side of it from the TB to the engine.

Eliminating the coolant lines on the TB=less hoses to worry about in my opinion. One of my TB hoses split the other day and I had hack it. There's nothing like the sweet sound of the add coolant buzzer

we were thinking it keeps the bac from overheating? but either way if you keep the bac, its prolly best to keep the coolant in it.

it doesnt seem likely that it's there to keep the BACV from overheating, since the coolant is most likely significantly hotter... the BACV is bolted to a nice big aluminum heat sink if theres a heat issue I doubt running hot coolant against it will improve the situation. It's probably for melting any ice that may have formed from condensation in extreme cold weather, so after the coolant warms up the BACV can do it's job if it was frozen at startup... I would probably just do the TB mod, ditch the hoses (plug the nipples) and just remove the coolant passthru piece that is bolted to the BACV, then you can keep the BACV in case you like your car idling independantly when you use accessories.
