has anyone had any experience with this VTA type blow off valve. It seems as though it slightly opens upon high boost and make a fluttery sound similar to compressor surge going into boost. The Stock BOV made a similar noise also when venting it to atmosphere as well.

 

I shouldnt even help you. I really shouldnt help you. Actually....im not going to.


stock BOV does not and can not VTA. Do a search-and find out why you cant VTA on an EVO---then go buy a different car please

 

r u retarded or something???? if you remove the recirculating hose from the intake and direct it to the atmosphere.... you get what, VTA. Im on an EMS right now so I am able to do that >>>> think smarter not harder with your useless post

 

whoa, i feel a flamefest goin

but in regards to Jm, i think hes correct when he states about the stock BOV: its not VTA. ever.

every single thread i've read emphasises that

 

Just because its says newbie under my sig dont get it twisted that i dont know my ****, im just not a post *****. For those who have more experience (not jmi11 whos a tool), both BOV SV45 and the stock have a slight flutter noise upon quick hard acceleration transitioning into full boost and quites down at full boost. Those with an aftermarket intake/cone filters experience this? Its not compressure surge im talking about here guys its a flutter into full boost.

 

wow...hahahaha.


Im a tool, but youre asking questions about a VTA blow off valve. It says newbie under your Name because you obviously never read anything one here. Because if you did...

1- you would have searched

2- you would have not asked a question about VTA. This becomes painfully obvious after reading maybe 3 of the BOV threads on EvoM


not to mention the fact that your half a retard. Why would you take the recirculating hose and point it towrds the "atmosphere?" A Blow off valve is meant to hold boost, the only reason you upgrade a BOV is if you run more boost than the stock can hold. Now why, if you had brains, would you remove the "recirculating hose" on the stock BOV?

SIMPLE ANSWER....the sound.


MY COMMENT.....thats gay and you, my friend, are the tool.



I could also rip out my filter, actually, entire airbox, and hear the sound...but why would i do that? Just get a recirc. BOV, hold your 'immence amount of boost' and shut up




Or get Vin Diesels car, and you can make the cool noise all the way down the road while you race Ja Rule.

 

Are you kidding me. This is the reason why i hate posting on forums. It's benchtop tuners like you that make things hard for everyone else. Your useless arrogant comments are pathetic knowing all you do is read post after post searching for something you can debate about to make yourself feel better. We all here know what a BOV is for and some may do it for sound and some may do it for performance either or its their choice.

1. my questions isn't about venting to the atmosphere. I know the pros and cons about it.
2. search for a full boost BOV flutter and you wont find jack!
3. If you have an aftermarket intake without a BOV return, the only choice is to VTA and with an EMS using speed density it's no problem. My question for the hundreth time isn't regarding VTA, its a flutter into high boost with both the GFB SV45 BOV and stock BOV with a back to back comparison.

By the way, why do you keep posting in my thread, didn't i clearly say for you to keep your off topic suggestions out of here. Go post in the Brokeback Mountain forum.

 

lol.........wtf?!?! you should search or better yet buy another car. get your facts straight.

 

Good Lord jmi11, you need to learn how to read. HE CAN VENT, BECAUSE HE'S RUNNING SPEED DENSITY, AS IN EMS and NOT THE STOCK MAF. And just for the record, the stock bypass valve CAN vent... all you need to do is take the damn hose off and cap the intake.

ANYWAYS spoolinspyder, I heard something about the GFB BOV that it kinda stutters at partial boost/throttle, same thing like my T-netics is doing (don't ask)... not sure if that's what you're refering to. From what I can guess is that it's opening prematurely... kinda hard to explain. Can you adjust it?

 

Yeah, man... Bro, is a wierdo! Either they cant read or they dont grasp the concept of Speed density and VTA. Anything thats not being recirculated back into the engine is considered venting to the atmosphere, Period!

Furthermore... The SV45 did flutter at light throttle angles, but not bad. It was impressive to see that a BOV this large could still be functional on a lightly modded stock turbo EVO. I later found out that the SV45 had two internal springs where the lighter one could be pulled out for lower HP vehicles. There is an adjustment knob on top of the BOV as well for fine adjustments along with the different springs rates. I still have the BOV so i may use it again once i feel the need to switch to an aftermarket ECU again.
The flutter i was refering though was at WOT @ full boost. It seemed as though it slowly began to open at higher boost but i was never sure. It was a flutter unlike the ones commonly heard with surging of the turbo. I'll try it again later on once i get more time for experimenting.

 

i just got an evo and i can hear the stock dv sometimes. sounds good enough to me; does the job

 

Sorry man, can't help you with the WOT fluttering... from what I've read, at ~3/4 throttle and between 10-15psi, the GFB (and Forge from what I've heard... also T-netics Raptor) starts opening and closing VERY fast... you'll see your boost jumping all over the place and the engine will be shaking. The sound itself is the sound you BOV makes when it opens, right? I'ts just not set to hold as much boost as your running if it's happening at WOT/full boost. Hope I helped.
