If you recirculate, it's basically working the same way as the stock BPV, so why even bother with doing the whole BOV mod? Maybe I'm missing something, so please fill me in.

 

yeah that does sound alot like my problem except i still got the stock intake. but my buddy thinks it has to do with the cheap bov i had installed. and it throwing the running too rich code not sure guess i am just gonna get a new brand name bov and see what happens.

 

You have quite more patience than me.

Because once a week these threads pop up, and you post in them.

 

turbo swap soon....

 

what about getting just cold side pipe and putting a BOV onto their to save some money

 

That seems to be what most people are planning on doing.

I believe that is what alot of people have done.

 

Your car is likely messed up because you bought a cheap fake thats leaking like a mother...

Guys, don't put BOVs on this car unless you're going to do a MAF relocate and the whole 9. Its going to make you slower.

 

I've seen a fake... horn BOV Thats SWEET! (sarcasm)

 

wont a bov make you lose boost in a nls?

 

not necessarily, afaik the throttle plate doesn't close on a NLS

and it will also cause a rich condition between shifts

its all for rice, it has no benefit on this car

 

If you get a BOV and recirculate it, you're golden.

Honestly, I've heard the stock BPV with a few different kinds of intakes now and if it's just a sound mod that you're looking for you'll definately find it in an intake... two birds with one stone there too. It sounds angry.

 

ive heard that they were slight smaller than a K04, like a K03 or something. thats just what ive heard tho. and i know Hahn is working on a K04 upgrade too for the LNF so i would think that would mean we dont have a K04? idk? lol!

 

We've got a twin scroll k04 for sure.

The Hahn setup you're hearing about is a k04 mod that most likely changes the compressor wheel shape. That way it'll flow more air while at the same time being a direct compatible bolt-on for the most part.

 

I <3 my BOV and it causes me no problems.

 

your a jackass, do some more research before ya start talkin out ya ass. and take that supercharge home son. a bov doesnt benefit the ss/tc at all? Pretty damn sure it releives constant psi in the turbo and blows off to extend the life of this thing. once tuned and boost gets cranked up i would def. recomend havin one when ya pushin 20psi+ hahaha. I know my car is messed up then i turn it off and restart it for now till it gets tuned, but obviously i already knew because i posted askin questions for ideas on what it might possible be. The bov and car runs fine pushin 15psi and just as fast as it was b4 it was installed. Then the comp. throwns a code after drivin around a bit. the more i romp on it the quicker it goes into limp mode.then i shut it down and restart it and the comp. resets and then is back to normal. till the process repeats itself.

 

Holy ****.

Ok, listen here, pal.

The LNF uses a MAF sensor to monitor air flow. Air flow determines how much fuel is necessary for proper combustion.

Can you follow that so far?


When you add a bypass valve that vents to the atmosphere, post MAF, into the equation it tricks the engine. The car is prepared to dump the fuel that the MAF has already accounted for.

When you suddenly release the air that was supposed to be burned, yet the fuel is still dumped, it causes a rich condition. Do you understand what the term rich means? Too much fuel. Do you realize that, if only for a second, a rich condition causes very poor performance and is not very good for your engine.

Now, a bypass valve that is recirculated, like the factory option, keeps that monitored air in the plumbing, simply rerouting it for a tiny second so it doesn't surge the compressor wheel. This air mixes with the fuel that was originally called for by the MAF and is burned properly.

To avoid this problem you need to run a recirculating bypass valve or relocate the MAF sensor post vent, so it doesn't measure the incorrect amount of air.


I'd also sure as hell hope your BOV isn't relieving constant "psis" from your turbo, or else its ******* leaking and you have a bigger problem on hand. I'd also agree with an upgraded valve for high pressures, but it needs to be recirculated or the MAF relocated for a VTA setup.

I hope you've learned something about your car today, jackass. Oh, and take that unwarranted TC big head attitude home with you.

 

thats what my BOV looks like

As for you guys fighting knock it off everyone for thier own. im not going to even get ******* started as i am a gm tech and hate getting involved i got not a single issue with mine at any time no problems at NLS no problems in reverse for gawd sakes..
The benifit of getting rid of the stock BOV is so i can put a better dam turbo on then this tiny pisser of a turbo that cant build boost to my tuned red line. one of the up sides of this lil turbo is the stupid fast spool.

either way you look at it it does all that same thing. as for redo6sc the maf does not measure the recirc'd air the stock bypass valve recirs the air within the turbo front the outlet flange to the inlet flange. the map sensor will see the change in pressure and report to the ecm its parameters and the ecm will do what it gots to do. even tho the ecm is expecting to those parameters of the drop in pressure because the ecm seen the throttle closed so it commanded the bypass solenoid open. If the ecm did not see the drop in pressure recieved by the MAP sensor it sets a DTC and depending on the class and programmed type it may or may not enduce limp mode.

The Maf sensor is no where near the recirc'd air look in my pics. the maf measure the density and the volume of the air in a calibrated area and there is also a temp sensor in with the maf sensor.

 

nice ^

turbo xs?

 

It is it is the RFL type H

 

good work but im not a fan of the bov. ill probablly be the first on here to try out the tial q on this car. i got a little something in the works for all these people that are having problems though. you'll be hearing about it shortly

 

Why not something like the alpha q? Should support more flow and won't have to worry about any of the BOV problems. I know it is personal preference between the two but I can't stand the sound of a vent to air type system, they sound obnoxious.

 

Right now it seems my car is running rich when i NLS. im tuned, and it seems to bog for a second and then go. I figured it was b/c my BOV is venting to atmosphere. I figured I would recirculate it and see what happens. After reading what I just read im assuming it wont do ****? input, thoughts?

 

Well, at least you could look at it this way... it won't hurt to recirculate it. Maybe it will actually fix the problem after all. It's worth a shot at least.

 

here is a quick suggestion, if you want a BOV,,, AND,,,,, zero driveability issues,,, buy the hahn setup like i have,,, their BOV system is fully adjustable, and it recircs back into the intake pipe... SEE IT IN MY VIDEOS.... www.youtube.com/badbaltguy it is also very loud, way louder in person than on videos...

 

problem with the alpha q is going to be hood clearance. its pretty big. personally if your going to run to the atmosphere i would just run a tial q.
