just curious.... im gonna be getting new IC pipes soon and was wondering what side did you all put yours on and why? hot/cold pipe or on your IC? dose it even make a diffrence where its placed? right now ive got mine on the hotpipe facing the front and pointing down a little bit. jsut look at my garage and ull see why i need new pipes lol

 

Use the seach button please.

BOVs are for ricers.

 

fixed

 

sorry, search button was used and some twin turbo holden was all that came up for "bov placement" but thanks for the link. and everybody else...why the open air maf ricer hate??? j/k, just working with what i got.

 

I hope you tell us which side you choose.

 

are you doing a bov for the sound or for the fact that compressor surge is bad in the long run?if your doing it for the right reason(no not the sound)id say cold pipe it allows for air to be release due to the air being more dense,but then again hotpipe is alot closer to the turbo which is good too,but id still say go with the cold side since the difference in distance wont make much of a differece

 

the technical reason to put it close as possible to the throttle body is that the "column" of air inside the pipe distance between the bov and tb will be minimized, making that air that hits the tb plate and 'turn around' smaller, and thus less lag....but the difference is really un noticable and its not really able to be proven, esp wont matter on a street car.

i prefer hotpipe, simply because it makes recirculating alot easier and no giant recirc hose stretching across the engine bay (mine is like this, and im going to fix it).

recirculating a bov on a pull-through mafs style car will do the following:

1. better mpg. yes, true.
2. quieter. less ricers, cops, and thieves to hassle you. bovs are not bought for the sound.
3. no gay richness between shifts. this is the reason for the better mpg, as well as less black burn marks on your rear bumper (if you have an N1 angled style exhaust system), from excessive richness. less popping, stuttering, and general crap that 99% of SR owners have that just peeves me.
4. NO STALLING!


my ka-t get ~250-260 miles to a tank of gas w/open bov or check valved (to cause it to not open at all and just surge). not only does it make the iacv work harder and the car wants to stall all the time. hooked up my recirc tube again (it was off because work clamps suck), instant difference. car gets 300+ miles to tank of gas again (both tanks were easy daily driving, occasional hard boosting).


just make sure the BOV has a direct vacuum line to a port on the intake manfiold. i think in terms of functionality and cleanliness. while putting it on the hotpipe makes my recirc tube short and clean, ill run a longer vac line, as opposed to vice versa with it on the cold pipe. being i can bundle the vac line with the harness, ill take that option.

 

^ +1 , thankyou, thats all i needed to know, think ima recirculate for few reasons but the main one is to not get flammed ne more. j/k u should see the black patch on my rear bumper and its gonna get painted white soon too. and my car stalls... and sputters....and atracts cops/ricers. is there a bov that is more geared tward recirculating than noise or would mine work just fine?

 

If you getting a BOV for the sound....shame on you! If you get it for the proper reasons, make sure you recirculate it. Your car won't run as rich between shifts, and won't have idle, stalling, or backfire problems when decelerating. I also hate BOV sounds. I also like to reiterate what was said early just to rub it in, so you do it for the right reasons.
