Self Explanatory

 

As far as sound, there is no blow-off valve like no blow-off valve. I don't like my competition to know I'm boosted.

 

I have Greddy Type S and I think it is pretty loud and I like the woosh and whistle sound.


but as Josh mentioned here....the best for the car is the recircualting valve.

 

Same here.

 

i have the hks super sequential blow off valve... and it's awesome... very loud... Ben's is loud too... he has the greddy...mine does a high pitched whistle at full boost and a strong kkkssshsshhhhhh noise otherwise... ben's has a high pitched sound all through... let me know what you do bro.... your car is hot yo!

 

XS Turbo RFL blow off valve....

 

sound clips pahhhlaaaasssseee.......

 

Here's a few. BOV Sound Clips (link)

My old BOV had a sweet whistle to it, I have to find the video again for folks to see it.

 

loudest I've ever heard!!!!

 

Which type was it?

 

it was an old blitz BOV, Ill ask Luke if he wants to host the video

 

i like the hks ones they sound good... old blitzes are nice too..

anything that sounds like them black civics from the fast and furious.

RFL=Real F*cking Loud

 

 

Now you guys are making me more and more eager to put my Greddy BOV on video because mine is stupid loud!

-Ben

 

But the RFL is juss REally F*cking Loud... louder then the greddy type S

 

It probably is, and if so, that IS really loud.

-Ben

 

make it even louder by putting a horn on there.

 

I thought the Greddy's were prone to leaking. I was gonna get one but after hearing some junk about leaks, I figured I'd put my money on a HKS. How long have you had yours for Ben?

 

it is. so I use it as a mechanical boost controller with the 2.87. I set it really loose and I am getting 10psi from the 2.87.

 

JAY25,

Is this the kind of Blitz BOV you had?



I really like the sound, but sometimes I think it's too quiet. You can hear it a little around 2000rpm, but it really comes alive around 3000rpm. But I always have to turn off/down the music. How does this compare to the HKS, Greddy, and new Blitz BOV's?

 

I think the RFL and most Turbo XS BOVs can be interchanged onto the Greddy flange too without re-welding using the adapter flange. so thats a plus if you want to switch up!

 

Hmm, my Blitz dual-drive was kind of quiet, I wouldn't be able to hear it from inside the cabin, just barely. The Greddy I can hear over my moderate music when its at a moderate level.

Hmm, I didn't know that. That IS a plus.

I was talking with guys at the local meet last weekend and they thought it was crazy how much air i was venting out at idle off the greddy bov. I tightened it to where no air leaked at idle, and you could barely hear it blow off after letting off at a upper rpm.


Noticeable differences: Car is more responsive, quieter, and idle is steady..



One thing they suggested I do was to vent the air from the bov after the maf..... There is a spot where my ambient air temp sensor should go, but mine doesnt fit. I'm considering jb welding a fitting there, and doing just what they suggested. Any opinions?

 

JB weld..."The Poor Man's TIG Welder"

 

greddy type s will always be my favorite.

 

Why thank you.

 

i think i will follow in ur steps in tightening the BOV

i turned it around facing the pass. side now... havent really noticed anything big yet . well considering i was stuck in stop n go traffic for an hour !!!

but had some lil gapped runs..

 

remember: the more air venting thru the bov the louder it will be!

my Greddy Type S is nuts. always loud.. works even better at sea level as compared to where i live (2500 ASL)

 

no thats not it, it was a blitz dual drive, you can hear it on this video me and Nismo2020 made racing a 2k2 auto.

 

I can't hear my Blitz DD at all with the windows rolled up, even with the radio off. But I don't have a fancy horn like Craig does.

 

 

the the funnel type opening on your BOV is called a "horn"

 

Heh, I have the same BOV as you Craig, and it sucks

It's only loud for me at super-high RPMs, and if you're moving (ie, not just revving it at a light or something), it's not loud enough to hear over the wind.

I might think differently when I change it to stick this summer but then again, I might just get a loud loud loud one too

 

I know what he was talking about, but if he has a Blitz DD, what other style is there? What's so fancy about my horn?

 

you got me I thought all the DDs came with a horn anyways.

 

My Blitz DD came with an attachment that looks like this:
