is it suppose to be this way

[bricksquad7]

is my bov suppose to dump back in my intake

 

[knochgoon24]

Yes.

 

[Rengar18]

Yep. If its not your car will run extremely rich when you shift. You need the proper hardware (refer to the tech articles) to run the bov outside intake.

 

[onefast2gdsm]

yes, our maf reads the air coming through, and the ecu adjusts the fuel accordingly, if it was dumped into the atmosphere without correct hardware, you would get idle issues and driveability issues.

 

[FwDdSm]

Yes it should definately recirculate back into the intake unless your running a maft or blow through setup.

 

[LiquidX]

Yes, why would you think otherwise?

 

[bricksquad7]

i just thought that my bov should dump else where because if its dirty air why would i want it back in my intake

 

[sax_man]

Its not dirty. It's already been through the intake filter and hasn't even reached your engine yet. You should read up on how a turbo motor works.

its not dirty air, the air filter takes care of that. the computer compensates for the rush of air and if you were to take that hose off and vent to the atmosphere, your car would run rich and in my case, almost if not stall when you press the clutch after blowing off.

Recirculating your boost is not only necessary but very useful for spooling, your A/F mixture and your driveability. The air (boost) being recirculated is not "dirty" or harmful to your engine. It's actually useful and without utilizing a GMAF+Translator or Speed Density will cause your car to run poorly if vented to the atmosphere.

it dosent reach the air filter it dumps in after the air filter, its weird how i ask a simple qustion about something and people tell me im stupid or i need to read about my car, i graduate from uti in 2 months. so dont question how much i know. and it is unfilterd air thats what air is called when it gets dumped in after your air fliter. sax man u clearly dont know and you should read how your turbod car works

Actually it would be considered unmetered air not unfiltered. The air coming out of your bov doesn't need to be filtered again.

 

[bricksquad7]

it hasnt ever been filterd goes through my intercooler up the piping out the bov and past my air fliter

 

[nc_dsm]

Air can't get into your IC without being run through your air intake filter first, Air goes through the intake filter, to the turbo charger where it is pushed to the IC and then pressurized to go to intake.

Exactly! The only way it isn't filtered is if there is no filter on the intake to the turbocharger.

Dear lord is this question seriously being asked?
People arent calling you stupid but if you come on here asking a question, and then when people give you the answer you argue with them, what do you expect?
Congrats your graduation from uti, obviously they didnt teach you how a turbo works.
The air in your intercooler piping isnt dirty, i have no idea why you would assume this because that would mean all the air your engine is receiving is dirty.

Like stated above, air gets sucked in though the intake, into the turbo where it is compressed, then it goes into the intercooler piping where it is still compressed. When the throttle plate closes all the unused (clean) air need somewhere to go, otherwise it would blow off your ic piping, so it goes out the bov back into the intake. This air has ALL been cycled though the intake filter.

^^that should sum up this whole thread, very nice post

here is a picture if that helps a little bit. now this system vents into the atmosphere but just pretend it has a hose like a dsm and route it behind the intake air filter.

it hasnt ever been filterd goes through my intercooler up the piping out the bov and past my air fliter

Obviously UTI needs to re-write their training program, the air that comes out of the BoV is the compressed air that is dumped out once the throttle closes, thus the air has already been filtered before reaching the turbo in the first place. I saw kids graduated from automotive courses come by the shop all the time looking for work (I use the term kid loosely since I'm only 22), we even had one kid trying to change the spark plugs on a diesel engine for like 3 hours just to see how much he knew (if they didn't teach you this at UTI, diesel engines don't have spark plugs).

Anyway, before you try to attack anyone just figure out that a lot of us have experience with these cars and also many others. DSMs have been making ordinary people into mechanics since 1989.

If this air was "dirty" why would it come like that out of the factory. The air gets recirculated after the filter and doesn't reach the engine. This air is as "dirty" as it was passing through the air filter. If u think it's dirty put a breather on the crankcase and plug the intake pipe where the pcv valve dumps then clean ## intake pipe and intercooler pipes.

Remind me never to go to UTI. You're actually arguing about this? It's a closed system. How does the air get to the BOV in the first place? It comes in through an air filter.

Despite the fact this is the newbie forum, this should get locked.

 

[DSMnoobsause]

if you graduated UTI in 2 months you did not take the full course and probably only learned how to change oil and do tune ups.
for someone that doesn't want to get flamed you sure do set yourself up.

Wow.

further proof UTI has lost total credibility. I hope youre prepared to get the same job some kid off the streets with a connection could have got, getting paid the same, when you graduate from that shithole of a tech school. If you think youll be making $50-60K because all the instructors that came to your HS (actually salesguys getting commission per student, so of course theyre going to paint a pretty picture for you), then i got news for you pal. Welcome to the real world.

obviously YOU dont know how a turbocharged car works. Any air in your intake obviously had to get there somehow........hrm, i wonder what filtering element it passed through? oh yeah, the AIR FILTER. its only how ALL of the air that reaches your motor gets there in the first place. Any re-circulation of air past the air filter (IE through your blowoff valve and back into the intake) has already been filtered and metered for. Thats why if you dump to the atmosphere, the ECU is thinking that air is reaching the motor and adding the correct fuel mixture for it, and when that air does NOT reach the motor the A/F ratio will run rich for that momentary lapse of air. Not as a big deal as the dsm crowd makes it, but you will foul plugs faster and you could experience other issues (bogging/studdering during shifts) and if your bov does not close fully at vacuum (idle, decel) then that will pull in even more unmetered air and cause even more issues.

Doesn't UTI use a silver 2ga in their magazine ads? Irony.
