I know there have been soooo many comparisons of these but my questions are to those with a bov. Ive heard that blow off valves cause problems and irritating issues. Do you guys agree? Is it worth the problems? Also i know you have to tune for it. Do you have to retune in the summer and winter for your car to run properly with it? If you dont get the car tuned but put a bov on how would it run? would it really not run at all( like sputtering and stalling alot) or would it just run rough? I currently have a forge bpv with k&n sri and just wondering if it would be worth it to move to a bov.

Thanks guys.

 

IMO its not gonna be worth it to switch. If all you're lookin for is more sound (which is all its good for on the stock turbo) it won't be much louder at all, and you'd have to pay the cost of all new charge piping, plus the bov, plus the cost of tuning, plus all the headaches involved with it. It's just not worth it for a little extra noise

 

listen to moderator gadget here its not worth it just get a kn sri and a forge bpv its not exactly quiet that way

 

he already has it he wants to go from K&N forge combo to BOV, that's why I said it's a waste of money

 

unless u have an upgraded turbo, dont waste your money on a BOV, just go with forge

 

Oh ok ya that's kinda what I was thinking. It is a lot louder but I guess it wouldn't be worth all the problems and money it would take. Thanks guys for your opinions.

 

not understanding the issues the BOV will cause, my boy just had a Tial added to his SS turbo it was weld in the charge piping he as a aftermarket intercooler. is there sumtin im missing? his car runs fine.

 

not quite sure what kind of problems. Ive just heard that after a pretty short time you'll start having corky things occur

 

I dont think there major problems just kind of irritating things to deal with. I dont know ask someone who has had one for a while

 

rice coming out of your exhaust is a common problem of a bov on a k04

 

And all the issues could be caused by the tune or somthing. Not quite sure if it was specifically cause by the bov. Ive heard a bov is hard to tune for. I guess thats because it throws the pressure off through out the whole system.

 

Hey i see you have a trifecta tune how do you like it? Ive been trying to call him but he never answers.

 

Only issue is traction problems . Other than that I love it. It wakes up the car pretty well. Havent had any issues.. Knock on wood

 

ok can someoone clear up what the problems of running a BOV on a stock turbo will cause.

 

He's on vaca to the 20th, but he does answer emails. He's ben answering mine. Just not as fast as usual.

 

i dont have a bov but i wanted one at first and read alot on it and asked around town so take this with a grain of salt

most of the problems seem to center around the maf its not really designed to be under pressure so it can read erraticaly if placed the charge pipe
if u leave it where it is your blowing off metered air and screwing up a/f ratio
most of these issues seem to be able to be tuned out after time but ive seen it described as a "process"
plus ive had to people tell me an external dump bov gets pretty anoying after 3 to 5k miles
some who has one needs to chime in though

 

The air that is blowing out of your BOV is air that was accounted for by the MAF and should be recirculating to the intake. If you vent it to atmosphere, that air that was accounted for is now gone, so you run into a short spike of a rich period where you now have just as much fuel, but less air.

Most people who run them don't have issues, if they are installed and set correctly. It's just a waste of money, though. You're going to pay $250 for the pipe and another $250 for the BOV, then another $50 for a block off plate for the old BPV, so you're shelling out $550 for something that just makes noise. If you actually get your car tuned for it, which from what I understand isn't really easy to do, then you're shelling out another $300 without a tune and probably $50 if you already have a tune. Just........not...............worth.............it . Those are some expensive grains of rice you'll be shooting out of your tailpipe.

 

We have called him and left a message like 3 times in the past 2 months so vacations is no excuse lol I sent him an email like 2 weeks ago and still no reply ill retry an email tomorrow

 

my boy has one with no issues and hes not tuned for it. i plan on gettin the turbosmart raceport becuz during my deployment ill have my turbo and internals done so ill be swapping, i have all the mods in my sig and will need a tune anyway for the turbo which isnt goin to run $300. I thought it would cause some major problems, it was just conflicting with wut i see daily from my friends SS with the Tial bov. but i do understand the waste in money for someone with no goals in upgrading the turbo just for sum noise, my stock bpv is pretty loud actually its really loud.

 

BOV without recirculation cause minor issues that can flare up, kind of like herpies. Its difficult to tune out the Rich condition that occurs after every time you let off the gas... Can lead to a CEL, sometimes doesnt happen right away and sometimes not at all, but chances are if you like to get into boost alot, you will throw the code.

 

hmm so your running a bov without a tune? Ive always heard that you have to get a tune for it to really run at all.

 

im not running a bov i still have the stock bpv, my friend has a black ss turbo: intake exhaust downpipe cams intercooler chargepiping he got tuned and then added the bov and his car still runs normal taking it a lil slow we did a clutch swap but there seeme to b no problems with the bov

 

oh ok
