View Full Version : ** Update**BOV on a S/Ced tC.... NO GOOD!!!
mtxgalant96 01-02-2006, 04:42 PM Alright everyone, I just got off the phone with Kenny form ZPI and he said I should GAIN power from the BOV cuz the BPV leaks boost all the time, no matter what one you have. So as long as a plug the hose for the recirculation I will be good. So BOV's are in and BPV's are out. If you have any other questions, feel free to ask or even call Kenny at ZPI and he'll give you a bit more info in detail.

motozen 01-02-2006, 06:07 PM why? :lalala:
Nick06tC 01-02-2006, 07:43 PM im kinda interested in seeing how it does and sounds. Let us know if you have any idle problems or powerloss.
KurtRS1 01-02-2006, 09:00 PM Ya I would like to see if it works too.
the_butcher 01-02-2006, 09:24 PM waiting!!!!!!!! :doh:
lol jk im being retarded :rofl:
mtxgalant96 01-02-2006, 09:42 PM Alright we got it in and it sounds freaking awesome. I have a vid, but has very poor quality sound. I made like 4 of them but none came out good. So I will try again later but hopefully you can tell from the vid.
oh yea, we set it up so the BOV connected to where the BPV came out from the hose from the throttle body, then connectd the top to the vac line, but left the recirculation that goes back into the supercharger open. have to call zpi and see what they think of this. had a litle bit of idle problems at first but fixed it by tightening the BOV. Its a fake type H RFL BOV, but it works. Just have to figure out what to do with that recirculation hose that goes back into the s/c.
as far as the powerloss, i cant really tell u cuz i havent got the reflash yet, cuz Checkered Flag Toyota here hasnt got what they needed in yet, so i'm running slow then fast and back and forth. Damn dealership!

Nick06tC 01-02-2006, 10:38 PM deffinetly need better sound bits
jwaggz82 01-02-2006, 10:56 PM he doesnt need better sound bits ...thats exactly what it should sound like. ....and I do agree... I like it ....I like it a lot. BUT --- is this a good setup for our engine? ....because this setup is changing the amount of air will the sensor be ok or will it not be reading the right numbers? ...I know this is an issue w/ turbos and bov's should only be used on large boost applications (that is what i have read). can someone comment on what I just said?
mtxgalant96 01-02-2006, 11:02 PM my friends were saying i should just plug the hole on the hose that was used to recirculate air back into the s/c. or i could go with a dual BOV, its a BOV that looks like the Bosch 110 Sport but has a spot where it has a horn shape where it blows off. I'm really looking into these, cuz they recirculate the air back into the supercharger and blows off. Friends were saying that recircualtion is more of an econmical thing, and shouldn't cause any problems. I drove around for a good 30mins on it and no CEL, and no problems. My car feels slow, but its felt like that for the passed few days cuz i havent got the reflash yet, so i think its jumping from lean to rich and back and forth.
Nick06tC 01-02-2006, 11:23 PM i want to know more about it. I had a Supra pull up next to me and the wife and kept giving it some and the BOV sounded awesome. He kept slowing down and just taking off and reving next to me.
I dont know why he would even bother with a tC. Wasnt even worth the gas for the embarassment he would give me. The supra was nice.
mtxgalant96 01-02-2006, 11:33 PM as soon as i get the reflash done and plug the whole for the recirculation hose, i will let u know how it feels. I'm giving ZPI a call tomorrow to ask them what they think. They were closed today unfortunately, but i will let yall know what they think after i talk to them.
jwaggz82 01-03-2006, 03:03 AM as soon as i get the reflash done and plug the whole for the recirculation hose, i will let u know how it feels. I'm giving ZPI a call tomorrow to ask them what they think. They were closed today unfortunately, but i will let yall know what they think after i talk to them.
please do - I would like to hear what they say also because nobody really has talked about using a bov. .....just the bpv.
DTRUONG_112 01-03-2006, 03:47 AM i like.
jwaggz82 01-03-2006, 03:53 AM sound is awesome. I hate how turbos dump out real hard but this is more on the lines of a nice release. Im wondering what zpi is going to say because ive heard a few peoples views that I know .... so i wanna hear stuff from people who deff will have their own view.
tikbhoy 01-03-2006, 08:10 AM :nails: hmm i want to hear the car under load vs at deadstop
tikbhoy 01-03-2006, 09:38 AM i know its posted somewhere but i just want to make sure, both inlet and outlet is 25mm/1" ?
Nick06tC 01-03-2006, 12:07 PM tikbhoy, I dont know the size, but when I did my BPV I kow they are the same size for inlet outlet....whatever that size is I have no clue.
tikbhoy 01-03-2006, 02:15 PM :P Thanks
im too lazy to yank it out and measure it.
Scion-ce 01-03-2006, 03:35 PM watching this thread
Nick06tC 01-03-2006, 03:38 PM hmm...if the idle isnt bad and the power is equal or the same. I am going to do this. I love the sound. As long as there are no negative side affects.
Simplyscion 01-03-2006, 03:47 PM sweet...Im gonna stick to my Forge simply for the fact that I dont want all that added attention when its blowing off(I had a Greddy RS that I was gonna throw on there but didnt want it to be real loud...the forge is still pretty loud but its not atmospheric...why dont you try running a BOV with a recirc like the Greddy to get a lil bit more power and consistency at idle and in between shifts...you will still hear it...especially with an intake.
mtxgalant96 01-03-2006, 05:38 PM well i looked into those dual BOV that look like the BPV with a BOV attached to it, but they are expensive. I'm gonna stick with the set up i have until i see problems if i ever do. I cant really say what a difference it makes cuz my car is running in some sort of safe mode cuz i havent had the reflash done thanks to the dealers and them not gettin in the device yet. Hopefully i will have it done tomorrow and i can let everyone know if it makes a difference.
apexjr 01-03-2006, 06:50 PM Mmmm... Man that brings back sounds of the ole MR2. =) Not quite as nice sounding tho... I bet a different BOV would sound shweet.
greenbox 01-03-2006, 08:25 PM HEY THATYS THE SAME BOV I HAVE THAT I POSTED ABOUT A MONTH AND A HALF AGO
greenbox 01-03-2006, 08:30 PM http://i11.photobucket.com/albums/a200/redbaron-tC/DSC00500.jpg
mtxgalant96 01-03-2006, 10:07 PM the vid has bad sound quality, so believe me it sounds alot better in person. I almost didnt want to post the vids cuz u couldnt hear the bov and it sounded weird. The vid gives the bov an echo affect. hoping to get a better vid soon.
Nick06tC 01-03-2006, 10:21 PM i posted earlier that you need better vids. Then I listened to it on the normal comp. SOunded real good. (sounded bad on the laptop that I always post from)
Nick06tC 01-03-2006, 10:24 PM Ok i just noticed that you live in VA Beach. Think we can meet up one of these weekends so I can check it out?
What other mods do you have?
mtxgalant96 01-03-2006, 11:00 PM Yea man sure thing. How about Saturday? As far as mods, i have tein s tech springs, trd short shifter, trd exhaust, trd supercharger w/ bov and zpi 9psi pulley. $2000 complete stereo system. Blue LED gauges and dash lights. Blue Cathodes. 35% tint. pedestial spoiler. And i have the 3 pillar pod on the way along with c2 oil pressure gauge, boost w. vac gauge, and air fuel gauge. Should have that installed by saturday afternoon if i get it all by friday.
Nick06tC 01-03-2006, 11:40 PM I will let you know. I want to go to the Arena Racing and Car show at Hampton Coloseum.
shuttlegoosecock 01-04-2006, 12:47 AM what kit did you get for the RFL to get it to fit???
mtxgalant96 01-04-2006, 01:09 AM to tell u the truth i dont know the size. Its a fake type H. My friend took it off his bmw and threw it on mine and we made it work. sorry i couldnt be more helpful.
bbsciontc 01-04-2006, 12:52 PM Just a quick question; your car didn't want to stall after revving the engine at idle like that? Cause that dumps some of the metered air out of the intake system causing you to run pig rich when u close the throttle.
mtxgalant96 01-04-2006, 02:33 PM It started to idle low and almost stall at first, but because it was leaking air. We tighened it and now it works fine so far. I just hope after the reflash is done today it will run fine. Let yall know how it goes after thats done.
DTRUONG_112 01-05-2006, 12:10 AM Alright everyone, I just got off the phone with Kenny form ZPI and he said I should GAIN power from the BOV cuz the BPV leaks boost all the time, no matter what one you have.

I thought that BOVs werent good for SCs? :nails: How would we gain power from it?
Because a good BOV will hold boost rock solid.
You can put a BOV on S/C's mustangs do it, and others.

engifineer 01-05-2006, 01:30 AM I dont know why he would even bother with a tC. Wasnt even worth the gas for the embarassment he would give me. The supra was nice.
Cause he was a moron trying to impress his woman... too must Fast and the Furious watching for him it sounds like :P
jwaggz82 01-05-2006, 01:36 AM i dunno what the right answer is but i wish someone that did would post. come on zpi ..... ? ..... lets hear your input.
mtxgalant96 01-05-2006, 01:50 AM forget everything! the set up is bad, atleast for me. I got my reflash done and the BOV was making my car lag in some gears. When i put back on the bosch 110 sport BPV it ran perfectly. So uness i can fix it with the BOV, i'm sticking with the BPV. Sorry if i got anyones hopes up, on this. Unless it can be improved, stick with the BPV.
Damn :| hope ZPI can make some noise with their intercooler kit.
bbsciontc 01-05-2006, 02:00 AM thats what I figured because a bpv is just a bov that recirculates air. If it ever leaks air under boost, your ecu will still add fuel from the lost air that was alreafy metered by the MAF sensor. Also if you rev it hard enough and then release the throttle while the car is not actively moving in gear, all the air released from the bov will not be entering the combustion chamber and I'm 99% sure it will stall or momentarily run like crap from being too rich, just as i've seen on dozens of turbo cars.
jwaggz82 01-05-2006, 02:16 AM thats along the lines what i was thinking - the MAF sensor is going to read the air all wrong because of the bov ..... the bpv is what ya need. .....which is too bad because everybody is saying the video sounded crappy but from what i heard....the bov sounded badass.
DTRUONG_112 01-05-2006, 02:47 AM it did sound badass, but better stick with the BPV.
Dakahn 01-05-2006, 03:21 AM How sad... sweet while it lasted, hopefully someone will put something to gether, either nice trial and error! :clap:
tikbhoy 01-05-2006, 04:01 AM Im guessing you just slapped it on.
BOVs on MAF cars isnt advisable depending on what mods you have. BPV will do a better job but if you really want it and not bog down adjust it properly.
there should be a nut on top to twist, rev it a little bit and then watch the valve close, it should close at idle if not then tighten it. Since its generic, im not sure if its a exact copy of the valves inside.
