BOV routed back into intake pipe... pros and cons
I'm piecing together my sleeper turbo kit for my 92 prelude. I want to draw as little attention as possible to my car to keep theft at bay and mostly to blow the doors off of people who think they're faster than me. I've explored the idea of running the BOV back into the intake pipe before the turbo so that it keeps the BOV noise down. The only con i can think of with this setup is the turbo actually sucking the BOV open if the turbo is strong enough (mine will be a t3/60-1 .82 turbine on an h23). Would this actually happen? Also would the sound completely be silenced, i would think so because the pressure would be the same.

I have this on my car from the factory ;P It's actually pretty quiet, definitely doesn't give away the fact that theres a turbo(s) under the hood. Dumping the air back before the turbo in theory also helps keep the turbo spooled. It wouldn't suck the valve open b/c the valve is operated by vaccum not by positive pressure.

I have my blitz bov routed back into my intake. It's not totally silent, but it's quieter, it sort of muffles the sound just a bit. I don't get the attention from pedestrains that I did when I had the bov vent to the atmosphere.

They should know your car is turbo no matter what. But the BOV idea will help a little.
Its just that big turbos make such an awesome loud sucking sound as they spool up...at least mine did. Hard to be sleeper with that.

Re: BOV routed back into intake pipe... pros and cons (HXMan)
i was curious about the running the pressure back into the intake stream. wouldnt this negate the purpose of releasing the pressure back to the turbo by just putting it back in? just curious.

the pressure you are concerned about releasing in inbetween the turbo outlet and the throttle plate. in the above situation the BOV is routed back in pre-turbo

First off. The cars that have them plumbed back into the turbo (always on the intake /compressor side) is needed for computer purposes. Usually found on cars with MAF sensors.
You could easily just plumb it into the intake tube. It will obviously quiet down the bov and also it'll help keep the turbo spooled inbetween shifts.

im sorry, but releasing the air charge back into the chargepipe, would really defeat the purpose of a blowoff valve.
if you recirculate it in the inlet of the compressor, you will be fine.
sorry, for the short response, i have more to say, just in a hurry....

pre turbo? as in the exh. manifold?
Air Filter -> Turbo -> piping -> intercooler -> piping -> BOV => Throttlebody(then IM)
You want it between the air filter and turbo....
