Open Waste Gate or BOV????

[240silvia]

What do you guys think????? Should I run an open wastegate? Or a BOV? I'm doing a KA-T next weekend. T3/T4, Spearo FMIC.... other stuff.... So, What do you guys think?

[IGSDann]

Would an open wastegate prevent compressor surge? I don't think it would, and it's bad for turbos...

[mrmephistopheles]

you're talking about two different animals here.
Wastegate is designed to vent excess exhaust gasses to keep the turbine from spooling faster once full boost is reached.
BOV/recirc valve is designed to vent boost pressure open throttle plate closure to prevent damage to turbine (eliminating compressor surge)

The benefit of an open wastegate is that of being able to keep regular exhaust flow more smooth, and having a free dump for exhaust gasses at full boost. Drawbacks include excessive noise and environmental unfriendliness.
The benefit of having a BOV is turbine longevity and neato sound. The only drawback is that it's a cop magnet.

What do I think?
I think you need to do more research before diving into this sort of project.

[S14DB]

Both, then you'll be the shit!

[clean]

hahaha, funnystuff, whats w/ the sig then? do you mean bov vs. dv? like diverter/recirculation valve

[Gladman]

Run both.

Mr M is right... you dont need to be doing this project quite yet if you're asking dumb questions like this... i'd get a friend who has done systems before to help you and make sure you dont accidentally route your wastegate vent into your valvecover or something

the two have absolutely no relation to one another except they both deal with turbocharger systems (two completely different pieces of it)

Ok man, I've had an SR before, I know what I'm doing. If I didn't, I wouldn't be doing it. This post was specifically designed to figure out other ppl's positions on this. So before you, with your 162 posts try to correct me, and say that I'm dumb, read the question, don't just assume I'm an idiot. I'm probably going to do both, but, I just wanted your opinion.

i've heard of no BOV systems w/ just an open air wastegate before...usually it's on race cars though IIRC

[Gladman]

1. Open wastegates dont damage anything, they merely vent the excess manifold air to the atmosphere rather than back into the downpipe where they kill exhaust flow and create turbulence.

ALL TURBO KITS HAVE WASTEGATES OF SOME KIND!!!

And wastegates are exhaust parts, bov's are intake parts... totally different, and both totally necesarry.

The Poster is asking if he should run a vented BOV (loud) or a vented wastegate (loud).. if i had to choose between the 2, id take the wastegate for its performance gains, venting a BOV doesnt do anything special.

If you ran a turbo larger than a T25 without a blowoff valve, it would blow within a few months. The twisting force on the shaft would eventualy cause shaft play, the wheels would touch the housings and nuke the turbo. You need a BOV to avoid compressor surge.

In your 918 posts you'd think you would have known to be more clear on your questions. You need both, your questions seems like you are going to run one or the other and not both.

On the BOV atmospheric does is good, but not as good as recirculated. Do a search and you'll see why, or think about it and you'll understand.

Wastegate, just make sure there is one first, external sounds great and works great if you do it right, internal works great too. Just kinda depends on boost levels and turbo you have. If you do buy external research them before you get it.

[240silvia]

I already have a external wastegate. The guy that I bought the mani off of had a Turbonetics one already on there, so I'm just going to use that one. I plan to run it open. Also, I'm thinking of running a SSQ.

I have a SAFC-II. I have read that there is a Air Correction feature on there that makes the KA able to run an open Atmospheric BOV. Anyone know where exactly it is on the SAFC? In the mean time, I'll look over the manual and see if I can find it.

Then whats your question?

On the AFC not sure, but why don't you just recirculate it.

[240silvia]

if you recirculate it, you don't really get the BOV "Bling" sound do you? Also, I don't know if the SSQ can recirculate.

I honestly can not believe you saying that just because he has so little posts that he shouldn't correct you, especially when you made a post thats sounds as ignorant as you did. And here you went and did it again "I've had an SR before" that is the most retarded thing i have read on this forum. Just because you owned an SR20 doesn't mean yyou know shit about cars, which it doesn't seem like you do it just seems like you made the first post realized it made no sense and then retalliated(sp?) and said "oh i was gonna use both" just because thats what everyone told you to do.


Basically: Just because you have high posts and have owned an SR20 doesn't mean you know jack about cars.

Also why do you keep putting the SR icon in all your posts about a KA?!?!

[Ian]

what are you talking about? ^

everyone knows your post count directly correlates to how smart you are....n00bs under 200 posts wont understand what correlates means


lmao

[DMC]

Ha Well then i obviously know what i am talking about because 48X>35X :jerkit:

[Nostradamus]

You're one of those people that would buy a fake BOV huh?

1.your original post deffinitly makes it sound like you don't know what you are talking about, whether you do or don't it sounds that way. 2. Owning an SR means jack sh**. 3.why is there SR in each title, after 9xx posts wouldnt you understand that's a title section and your post is not about a SR.

To answer your question I have a KAT and i run a 1st Gen DSM BOV, it's recirculated and i still here it sound off, its not as loud, but you here it. Running an open BOV with basic management on a KAT is an extra pain.
You probably dont want my advice though because i only have 22 posts, i must be an idiot!

Yea, I only have 49 posts so I def. can't say anything. I will also be recirculating my bov when my swap is done so I'm def not cool because my bov won't sound like i killed an animal everytime pressure is released. Anyhow what do I know i dont even have anywhere near 100 posts yet. I'll shut up now. Theres an SR for ya!

[240silvia]

Mark.... WTF has this board turned into.... It's used to be full of guys that were not fucking dicks. Usually, guys that have a low number of posts don't really know a lot about the subject. However, Kevin please delete this post. NOTHING productive is coming out of it. To much emphasis is being put on being a smart ass, and not, where it should be, the question. It was ment to be if you perferred the two or not. Maybe I worded it wrong, but, doesn't give any of you reason to be a dick. :fawk2:

As far as the SR icons go, when I have my car with the SR, I just got in a habit od clicking it, why in the hell does it bother any of you? Fuck, it's just a icon, shit, just shut up and get over it. And if I didn't know anything about cars, why would I even bother doing an SR? I did half the swap myself on one again, STFU, you don't know what you are talking about.

CLOSE THIS POST

[DMC]

Boo frickin hoo if you recirculate it, you don't really get the BOV "Bling" sound do you?
Ok man, I've had an SR before, I know what I'm doing.
I understand that you didnt work the questions right, but these 2 statements alone make you sound like a fucking moron to me, actually mainly th ebottom one.

[s14turbosilvia]

my goodness you guys, cut it out. The poster obviously knows that both parts are required.

I have the same question as him. Both parts make noise. And to Nosterdomis, if a bov was just a bov with no "bling" sounds, then why are so many sold with different sounds, inserts, filters, etc.

The man is simply asking wether he should vent one or the other or both. I'm wanting to do both also, and I probably will end up that way. It's possible to vent both external and internal wastegates. I'm only curious about the sound of a vented bov vs. a vented w/g, and both together, because the amount of sound your car emits does matter to some people. And no, we're not the type of people to buy fake blow off valves, but thanks for the comment anyways.

[XxJaPxOxNeEs23xX]

or is he talking about either bov or bpv

[ruthlesstyper]

"I did half the swap myself " haha. u must know what ur doing then.

[North240]

I answered a question about a recirculated BOV on my KAT in my post, i just added my $.02, people shouldnt act all tough. I dont know it all and i'll admit it, so i dont claim i'm the shit because i turbo'ed my KA.

** I have also run an open wastegate on the KAT aswell and it sounded pretty good, a loud gushing noise if i may add, i chose to re-route it to my exhaust because i like being quiet.****

Good luck with the KAT.

Oh no! My knowledge on turbos is inf3ri0r because i have 162 posts on a message board with kids asking these questions like yourself... maybe my 4000 over at clublexus doesnt mean anything either, or what about my 2500 i had at rx7club? posts dont mean jack... when the owner/manager of SP came on a supraforums with no posts do you think people listend to him? hell yeah they did...

You had an SR huh? from the tone of your question, i bet you didnt install it or do any work on it did you?

I'm saying you're ASKING a DUMB question, get over it! Though now with your response of telling me to reread YOUR post; when you OBVIOUSLY didnt read MINE; I can tell that you ARE in fact DUMB and probably around 17 years old

Other people's positions on open wastegates or blow-off valves? The whole problem is you act like the two are related, when they ARENT... if its the tone of your message that I didnt get (and hardly anyone else did either) then I apologize... but dont try this internet tuff-guy shit with me kid, i dont give enough of a fuck :rolleyes:
My logic is, if you ask a question like that; or at least cant type clearly enough to express a simple question; then maybe you dont need to be doing this

better method of question-asking:
"I want my car to be loud on the turbo-side, but not too loud... so i only want to run an open-vent gate or a open-vent bov to keep the noise down... which should i run?"

As for this board turning into a bunch of dicks... thats your opinion of it... I call it "jaded"... check out freshalloy to see what i'm saying...
people are so sick of bandwagoneers and idiot morons asking the dumbest questions, that they tell them to either "search" or flame them (Even mildly) and tell them to go to nico or something...

the board is growing up; its members are starting to not tolerate misinformation and little kids whacking themselves off about cars they dont own (anyone remember supraforums about 3-4 years ago? lol)

[sileight_04]

I agree there is no reason for all of this back and forth bickering. the guy has no idea what does what and obviosly doesn't seriously want anyones opinion. If he did he would relize he was wrong and say thanks but, nope. so i think he has gotten enough info to know whats up. So just let him go buy his stuff and get someone else to put it on. if it blows it blows. and before anyone starts flaming me about how many posts i have on here (i don't even think it is 10) it's because I just come on here find answers to questions and most of them are already answerd so i need not post the same message again like so many do.
