there is no pressure in the Intake
and theres not enough vacume coming from the enging to open the bov period.
bov will open at really high vacume which if it would open would end up letting air our of it casue thats what its made to do while the butterfly opens at very low vacume and lets a lot of air in
its comparing apple and oranges yea there both a fruit but thats where it ends
yea you could do all of this yea some dumbass that doesn't know his ass from a cresent wrench might belive you have a turbo by seeing a bov but its compltly useless it will not do anything nothing at all
and an Intake
doesn't even creat 1 psi and change in pressure will be a negative (vacume) untill the throtle body close's in which case the air will instanly stop even even with a ram air system nothing will happen no pressure no bov needed
