Bov Recirculating

[jr240]

alright so where is the best place to put the bov . People say the cold pipe and others say the hotpipt. Its confusing me. And how would i recirculate the bov so i wont run rich aiight thnaks

[daniel240]

generally you want it close to the TB

[jr240]

would i need to recirculate it or let it go to the atomosphere

if you are tuning the fuel in some aftermarket way such as a S-AFC, e-manage, or stand-alone then you will be able to tune the car to run normally with a open atmosphere BOV. but if you are running a rising-rate fuel pressure regulator or a hacked MAF set up with your turbo it may be a good idea to recirculate the BOV so the car wont run rich when the BOV is venting

[jr240]

sorry im a newbie whats venting , so if i wanan hear the nice bov noise i just need to get a safc so i wont run rich wen shifting

[TurboKA37]

by venting i mean when the BOV releases the air. first off are you going to be buying a kit or making your own?

[jr240]

im going to make my own

[jr240]

its going to be on a single ka24

[TurboKA37]

single cam you mean? well i suggest doing some searching through the forums because there is a lot of useful information on how people have pieced their kits together on here. search button link is at the top of the page

blow through mafs will let you vent to atmosphere. Sure its easy enough to recirculate but some of us ended up with vintage HKS units and no recirculation fittings.

[jr240]

did u use the blow through mafs or u just got the hks units so u dont have to recirculate

[daniel240]

blow through, means the mafs is after the turbo, in the ic piping, you can put the bov before the mafs and there is no need to recirc. it.

[jr240]

so i put the bov in the hot pipe then intercooler then the cold pipe and put the maf sensor. how would i put the maf in the ic piping cut a hole or what

[TurboKA37]

or you could put both the MAF and BOV on the cold pipe just as long as the BOV comes before the MAF. and im not really sure about how to put the MAF in the piping. i know that the people running hacked MAF just use the sensor in the MAF but if you are going to use piping the same size as the MAF unit you may be able to clamp the whole MAF unit in a cut-out of the cold pipe piping

[jr240]

haha that sounds hard man ill just stick to the recirculating haha make people beleive i have no turbo

[jr240]

lets get this straight now the the bov on cold pipe and the maf is where ? in the intake with the airfilter, the i recirculate the bov to the maf or intake ? im a newbie ahha doing alot of research

[TurboKA37]

in order: air filter, intake pipe with recirculated air then MAF, turbo, hot pipe, intercooler, coldpipe with BOV, then throttle body. if somebody that has a blow through set up would help out on how you set your MAF in the piping that would be helpful

[jr240]

so the recirculated air hose goes before the maf ok i got it , u think it be cheaper just to do this or get a sr20det swap

[jr240]

can the s-afc II can solve the open atmosphere bov promblem

[andrave]

supposedly. it advertises that it can.

[daniel240]

so the recirculated air hose goes before the maf ok i got it , u think it be cheaper just to do this or get a sr20det swap

Wrong. the recirculated air hose goes after the mafs. the mafs has allready calculated the air, it just needs to be feed back into the system. so make sure it is after the mafs.

[andrave]

yeah I was thinking that... good call.

HAHAHAHA!!!!! best post ever! oh man.

i would highly recommend researching turbo systems before attempting this. especially if you consider going sr20 because this is too complicated. good luck!

[jr240]

aiight thanks everybody for the help im doing mah research man so its the air filter,the intake pipe then the recirculated hose, Maf ,turbo , the hot pipe, then intercooler, then the cold pipe with the bov then the bov is recirculated back into the intake pipe

[TurboKA37]

actually i made a mistake the recirculated air has to be put in after the MAF. i dont kno what i was thinkin sorry bout that. whether you are going to have to recirculate the BOV really depends on the way your kit is set up so i wouldnt worry about it right now
