Ultamate Blow off

Any one who plays underground two has probly heard the blow off valve sound that a few cars have as the cameras go over the first few cars in the URL races. It sounds like you make a high pitch noise with your mouth then make your tounge hit up and down quickly. Its hard to explain. But i was wondering if anyone knows what blow off valve this is. I know its not fake because i have heard it before on a racing video. Any one know? Thanks

:eek7:





um...HKS SSQ is a very popular BOV...

the Apexi Twin chamber is also a very popular BOV...

Tial BOV's have a very unique sound...

but i cant help you with that description, but BOV's sound different when releasing different levels of pressure (or boost)...so odds are, your not gonna be able to match the exact sound that is on the video game because it could have been mocked after a car with 40psi single turbo and you have a 15 psi TT...so yeah...good luck with that!!!

I think it might be the tial. I heard all the other ones. I need to hear the tial. any one know where i can hear this tial bov?

its the same sound on 2 fast 2 furious. the sound that the supra lets off

if you want to hear a tial, the only car i can think of off the top of my head, that has the tial BOV is a 300zx single-turbo conversion. go to http://www.z32power.com and download one of the many videos. thats a tial BOV....

FYI: that is joel grannas's single turbo 300zx convertible pushing well over 600rwhp...to my knowledge.

heres a site w/ tons of blow sound clips

i think the one u are looking for is the HKS SSQ look at the link above and hear the MR2T leaving and coming back

Its the blow off valve on grip video four on the night time street drifts in the ice.
I dunnno. haha its hard to find

if you asked me i love the way the turbo XS RFL sounds is the loudest blow off valve and if you set it right you wont have turbo lag and you can have it as a open atmosphere blow off valve

what??? a BOV alone doesnt cause you to NOT have turbo lag. it may help the case but not solve it. and by open atmosphere you mean it releases boost pressure into the atmosphere, then yes it does that but so do most aftermarket BOV's...and yes the turbo x's RFL BOV is "Really F***ing Loud"!!!

yes it releases boost pressure into the atmosphere i didnt recirculated and in this forums a dude told me that you have to recirculate the blow off valves for 3000gt or stealth

you dont have to...that is what should come stock. recirculation is the best kind of valve so your not wasting good air, but it isnt necessary. plus recirculation valve's dont have that "cool" sound...:D

anyways recirculation valves basically do as the name implies. they take that air that needs to be "blown off" and puts it back into your usable air stream. through more hoses...
most, if not all stock systems have a recirculation valve set-up that recirculates the air in the boost hoses back into your stock air box after you release the gas pedal...the air in your boost hoses have to go somwhere or else they will just sit in your boost hoses and bog down your turbo's spooling rate.

hey guys, new to the turbo world. How much do one of these blow off valves run? I am very interested in the turbo x's cuz you said it was the loudest. How much am i looking at for one? and also, labor?

you could always look it up on sites and see the price. I think they run like $130 - $270 or so depending on the BOV

and the turbo xs is the loudest? Cuz i mean they all sound the same right? It is all jus based on loudness right?

actually they all have pretty distinct sounds...but i would say the turbo x's RFL BOV is probably one of the louder ones i have ever heard...

i got one in an ebay auction for 58 dlls and its pretty simple to put in your car i just invented a plug for the intake hose and the rest was history just disconected my OG bov en conected the RFL in its place and adjusted to the psi im running and thats all didnt need the installation kit for 3000gt

i can almost guarantee you that its the HKS SSQV bov..i personally thing they stink cuzz all it it is a small little chirp, but to each its own i guess..

this thread is 3 years old...cmon bro...

dead, let it die...

Wow
