just got my turbo all done on my b16 eg ... and runs great !!! hondata is tuned and everything, my only question/concern is....... is my bov working properly??... i bought it used. its a hks ssq, and i know you need to be making boost for it to sound but on some cars .. like if there in nuetrual and rev it will sound... on my car it wont sound...just wondering ?? iamnew to the whole turbo thing soo dont flame too bad if it was a dumb question...............

 

All depends what size turbo you have. My friend had a 2nd gen eclispe with a greddy type s and he could rev in neutral to pop it off. On the other hand with my i had a t3/t04e with the hks ss. I could not pop it off in neutral

 

hondas bov will only blow off when u hit boost never heard of any bov like an eclipse just reving up

wrong.

mine goes off anytime i back off the throttle.even in vacuum. same deal with another turboed honda im familiar with

 

mabe its just me but i find the idea of sitting in one place and trying to get my BOV to sound is kinda ghey.

 

it doesn't matter if it's ghey or not, his BOV should be working, and I bet when everyone put their first turbo kit in they wanted to hear the BOV a couple times, including me, and you did too (don't lie, it's really ok).

 

actually i drove my car to hear mine i didnt sit there like a goob and start revving my engine.

 

what do you think he was going to do, sit there for an hour and rev his engine. I meant like once or twice maybe even three times. and I guess you took the lie option there!!! Either way i don't care and you obviously care too much goob

 

if you boost in reverse, does your BOV suck in air? lol....it's a j/k, just like most of this thread...no need to flame

 

alright cool guys.. thanks for the back up........ and no i dont sit and my car and rev.... i was just wondering if it was suppose to go off or not.. i know all cars diff...thanks though........... peace

 

The real answer is...it depends.

It depends if the pressure balance between the vacuum side of the diaphram when compared to the boost side of the diaphram is right on the threshold of breaking over or not. it also depends if your turbo can make boost in neutral, most apps do not make any substantial boost without engine load.

Simply, if the BOV is really sensitive to vacuum changes it can be made to blow-off in neutral. A tight BOV or one which requires a large differential between the two sides of the throttle plate will usually not blow-off in neutral.

So, 90% of the time the BOV should NOT blow-off in neutral, but some apps that build boost in neutral or have sensitive bovs' can.
