I doing a bac delete

I am doing a bac delete on my 1989 GTU. I was wondering if I can block off the coolant passage hose that goes through or the bac?

I’m just trying to open more space since I was doing a air pump delete.

Doesn't the BAC control idle speed? So if hes got any accessories on the motor (A la A./C or whatever) wouldn't it cause the engine to run like *** when theyre on?

Kind of. It's more like a fail safe for when idle drops too low like when placing an unexpected load on the engine. The set screw really controls the idle speed.

When the engine is cold, and when driving in cold climates, the possibility is much higher. I've been driving fcs for 20 years without BACVs and never had a problem, but I've also lived in South Texas, Florida, and Hawaii during those times.
