i went to install my godzilla bov and noticed it had more than 1 vac. port on it? no instructions on the vac. ports in the box. a friend told me 1 is for turbo cars and the other is for blower cars.? which do i use? i cant find the info on turbonectics site. do i use 1 port and cap off the other or leave it open? which way is correct? seems like a wg hookup kinda. maybe use the top port from the turbo to the top port of bov and leave the side port open on bov/or cap it off.? im lost please help.
