My aps bov has to hang upside down because the logic perforamce upper ic pipe has the hole at the bottom facing the ground. So the top of my bov is facing to the ground. IS that bad? I do notice a flutter when i hit the gas and stop shift before higher rpms and when i dont build enough pressure it flutters which i think is normal for that. WOT it sounds nice.

 

yes. your car will boost backwards. oh noes!!1!

it shouldn't be a problem unless things are not mounted correctly.

 

the orientation of the bov to the ground has no effect on it's functionality. If it flutters it's because the spring is too tight (if it's adjustable) or vaccuum line isn't properly routed.

 

bottom of bov routed to ic pipe and side of box to the intake...vacuum hose connected like it should...aps does have adjustable spring does it?
