Hey guys I'm looking to get a descent BOV for my VT and was browsing around on the internet and found a few. I saw that Greddy has a couple for our cars but damn expensive, and then came accross one from Forge (listed on a site and eBay for $170sh...) and was curious if this would be a good starters one.

Yesterday I read a thread on here about a cheaper method on making one but being my first turbo car, and the other love of my life aside from the wifey I just want to make sure that whatever I do that it is done properly. Here's the ebay link to the Forege BOV, hoping I can get your inside scoop. I'm from Miami, don't know of many VT's in the area so I'd be willing to go another route on having a BOV if it's cheaper but would need help and of course don't mind paying for labor. Thanks for all your help!

Personally, I would just unhook the bypass pipe and cap it on the intake side. The Forge will hold boost a little bit better but it is not going to be significant..

With the bypass mod, you wont spend a dime and you will get pretty much the same sound.

Otherwise, the only BOV I would use with the stock cooler would be the Forge. I loved my forge and now another member is loving it.

The forge should be everyone's ONLY option when considering a BOV on the stock Intercooler. It is the only feasible option in my opinion.. Spending money on a upgrade cold pipe, only to probably install an inferior BOV to the forge and needing to block off the stock location seems silly to me.

The forge is a VERY well made unit with an AWESOME response time (ask anyone who owns one)

Again, if you are just doing it for the noise, unhook the bypass and call it a day. If you want to hold boost pressure a bit better and never have to worry about the diaphragm of the stock BOV, get the forge..

The only reason I sold my forge is I couldn't use it with the aftermarket FMIC kit I made!

Cool, so overall with the Forge I listed you would say it's good? again sorry it's my first turbo car so all this is new to me LOL do you think that price is descent ($170)? Thanks for the support Turbosocks!

166.50$

Definitely a good BOV!

Hey thank you once again Turbosocks, I greatly appreciate it!!!!!!!!!!!!! now I gotta see about installing it LOL

1st engine mod, more to come in the future... (not a real engine mod but this will do for now) I CAN'T WAIT!

I'm 29 and feel like a little kid all over again :crazy:

 

[Turbosocks]

the install is VERY easy. I could walk you through it with my eyes closed..

 

[ssmaximuss]

Cool man, I greatly appreciate the help!!!!!

Should I message you once it comes in to see if I can get a walk through? Do you know what tools I may need to complete the install just to have them ready? (again sorry, total new-B!)

I've never been in a helpful forum like this before, from the reading and everythinig else I gotta say you all are cool peps!

Ignore the question, a little more research implies that it maybe octane related. Time for testing.

I am not interested in noise change but performance change. Is there any noticeable change related to the BPV disconnect vs BOV?


Would doing the BPV disconnect or installing a BOV eliminate the apparent surging, probably not the right term, I sometimes get on acceleration?

thanks again Turbosocks, I'll be sure to refer to that link once I'm ready toinstall. Will post vid to see what you guys think

Have a great day!

Cel

By any chance did the BOV throw the CEL?

I'm a complete newbie to the import turbo tuning thing. So please bear with me.

Does a BOV offer any more performance? It seems to me that keeping pressure up between gears is a good thing.

Where I live I have to get emission tested. Will the BOV be a problem with that?

Will a BOV harm my fuel mileage?

I hear you brotha, Im in the same boat, though here in Miami we dont get tested for emissions. I'm hearing that its basically for show (depending the one you get), I dont think to my little knowledge that a BOV would offer much of performance gain.

You absolutely do not want pressure in the system when you take your foot out of it, the sound of the air coming out is a good thing. The blow off (or stock recirc) valve is absolutely necessary to your engine, especially with the efficient twin scroll unit we have. An aftermarket BOV could possibly make nominal performance gains if there is some relief programmed into the stock unit. Sometimes they are designed to leak during boost spikes. Also, with a car like the Veloster that uses Manifold Absolute Pressure (MAP) instead of mass (MAF) sensor, you don't NEED to recirculate the air, which technically could raise the temperature of the air going into the engine. Basically it's probably better to release the air than recirculate. From what I have read, if you plan to tune the car eventually, it's probably a good idea to put in an aftermarket BOV. Also, the only thing you can really do wrong is use a spring that is too stiff. If you use too stiff a spring, it will not allow enough of the pressure to escape and build pressure between the turbo and the intake and reduce the rpms of the turbo. So basically not allowing the air to escape will cause lag when you open the throttle again.. In addition it will likely actuate the check engine light (CEL) as I see someone already had that experience on here because the pressure gets too high in the intake manifold. So basically, you WANT the excess air to leak out when you let go of the throttle. BOV is not to be confused with a waste gate. The BOV does not control boost, the waste gate does. It will not affect your emissions or mileage. I imagine a smog inspector could ding you on visual inspection, but just install the factory recirculation hose or put the factory valve back on for smog.

Hey Socks, did you do any logging with torque or anything when you had the Forge BOV? I wasn't going to bother, because I don't plan on increasing boost any time soon. However, with how funky our boost seems to spike and drop, etc. I was curious if the Forge BOV helped any of that by holding pressure any better. Right now I've been just messing with trying to get the stock bypass to make different noises because I'm a geek. But if a legit BOV would help even out boost pressure then I think it might be worth doing.

Also, for going in for warranty etc. can I pop the stock bypass hose back on or anything like that or would I have to remove the BOV. I'm just thinking ahead in case I ever need warranty work on anything turbo system related.

from my good friend Turbosocks:

Re: Forge BOV



It threw a CEL when I had the yellow spring installed.. Install the green and you will not have any CEL problems!

 

[Stone Axe]

So now for my newbie follow-up questions.

The excess pressure limits the turbo speed? Does it keep the turbo spooling faster between 1st and 2nd gear? That is what I really want.

 

[cubancaddy]

when you take your foot out of the throttle, it opens the valve and releases the pressure so the turbo can keep spinning and high rpms.. not sure what your question is, but I'm sure the turbo rpms are similar between all the gears..

 

[rickykegs]

I tried all of the different variations. Left the hose open, placed a filter on the end of the hose, tried some other ways to get the "swoosh" louder....all of which threw my CEL on. After a while, it goes away. I just put it back the way it was even though numerous people have said on here that it won't affect the turbo in any way at all.
