new blow off valve

[Bay_Area_sr20det]

i have a s13 with a redtopsr20det with a frount mount and a boost controwler, runing 10 psi. and i need a new blow off valve.

should i go with the ssqv
or the greddy type rs, i like the style of the rs. but i herd the ssqv is awsome.

and anyother cool bovs out thare? performance wise, i dont need them to have lights or anything in them.

[TougeNinja]

SEARCH DAMMIT, theres sound clips everywere. IMO the louder the better.

but seriously search first before posting.

[whomiked]

awsome boost controwler

[Bay_Area_sr20det]

i dont care about the sound i was wondering about performance. so searching for sound clips wont help me any. just wondering what people have experanced from thare aftermarket bovs.

[drftwerks]

y do you NEED a new one?

[Bay_Area_sr20det]

because my stock one is leeking and the aftermarket one i bought is cheep and it does not open fully

[kensreliableb18b]

either one is fine; wont leak. i doubt you'll be running too high of a boost to consider other valves.

[sblack13]

run without one. i had both and they are both crap, only blow off valve i liked was the greddy type r.

[samplesurf]

i personally like my blitz dd ,holds boost well and doesnt sound like a seagull like the ssqv but more like a series of releases under a little boost like a snake hissing or somethin and one big whoosh of air at full boost and u can get it in a kit made for the sr

Genius...

Lets just not have a BOV, and have the air SLAM into your compressor impeller adn THEN decide to make its way out of your intake

retard

But to actualyl give you an answer, BOTH are outstanding units. I personally liek the Blitz, or the ARC, mainly becuase i have bth adn the HKS is just annoying. The greddy is a well built unit that is a little smaller than most BOVs, so you do not have to worry about the positioning, liek i did my HKS. It woudl hit my hood if i didnt haev it just right.

its all preference, if i really wanted to do a blow off, i'd do recir. I've never had one problem running with one. It's just one more thing that can break, and there are plently of cars running without them with high boost. Yes i do admit it's harmful for the turbo, but it's not going to shorten to lifespand by 50% of even close to it so i'm not worried. I know people running years without them on sr's no problems. But yeah, back on topic.

[nsn240]

i really like my RS :)

[Wei240]

there's a pull type, and push type,
but either bov's mentioned are good ones,
some even run ebay ones with decent results...
and in the meantime, you 'can' run without one, people have done it and seem to like it, better response and such, but technically, it shortens life of the turbo

[!Zar!]

Running without a blowoff valve isn't for the cheap, it ISN'T a stupid idea.

I'd suggest running one if was want sexy throttle responce, but due to the compressor surge, it will kill your turbos life; depending on boost levels.

As for running with a blow off valve, I'd suggest the hks ssqv or any pull type bov's.

Unlike other blow off valves that are push type, pull types will not leak under high boost conditions nor under vacuum at idle. They can not physically leak under any level of boost because boost pressure also keeps the valve closed against its seat.

[Bay_Area_sr20det]

ok, first of all. im gona run a bov....LOL... i like to have deexcelaration when im going into the turns. i live in the santacruz mountians. and its raining.

my friend is going to let me barrow his BRAND NEW SSQV and im gona recirk it. but now that i think about it those are alot biger that my car can handle. and im not really excited about the screeching sound.

i like arcs style, so whats better arc, greedy rs, r?

[silentstyle1]

Go with the Blitz Dual Drive, my buddies go it on his S14 knotchtop, and not only does it sound sick, it performs well, and adds a good performance factor.

[Slidin240Wayz]

Since when does a BOV increase performance?

Carlos

[Bay_Area_sr20det]

better throttle response over stock and better/faster deceleration.

[nissantfsx]

I have a Greddy Type-RS. Its been on my car for over a yr now...no problems at all...I love it, both the sound and its appearance. The swoosh sound that it makes is nice. If u want one thats louder and unique, you should choose the HKS ssqv, unless u dont like the "seagull" sound that it makes...lol
I would say both are good choices. As for the Greddy Type-R bov...i dont think it would make any noticeable sound unless u rev ur car to high RPM's, please correct me if i am wrong about this...but thats what i heard from people.

[GSXRJJordan]

I hate contributing to a thread like this, but here goes...

Let me start by saying that I worked on a Formula D car this last season (S14 w/RB25 and a custom Garrett turbo, similar to a GT35R) and the owner/driver ran with no BOV. The top end turbos have vents around the outside of the intake that are specifically engineered to eliminate the need for BOV's, because as was stated earlier, they do NOT improve throttle response, they deaden it. Drifters espicially need the instant throttle response for mid-corner corrections, and most guys that do run BOVs run em so tight that they only dump when coming all the way off throttle (like I do in my SR). BTW, running big turbos with no BOV makes for [email protected] compressor surge noise - the crowd loves it! Turbo seals do not ~

I agree that for big boost the pull types (HKS) are def. better than push types, but for 10lbs or less, it doesn't matter. I run a Megan BOV ($ free) on my SR at around 10lbs, and it's adjusted tight enough to not leak under full boost (which means it doesn't actually blow off until the compressor surges a tiny bit, I get about 3 "chur/chur/chur"s from the turbo and a big PHOOOOOOO from the BOV coming off full throttle). The only BOV I've ever heard that's louder is the Blitz, and the quietest is the Greddy Type R (also stated above).

If you're building a street/stock motor, you can't go wrong with anything you find. I can't recommend flEaBAY knockoffs, but anything else will serve you right, just buy based on what sound you like ~

[Bay_Area_sr20det]

i really am coming to like the rs because of its style and i like the woosh. bit im going to install the ssqv today. im a fan of "look a nice red sports car i wonder if its fast!" me *laughing inside, takeing off slowly, then mashing the peddle in first, whale shifting into seccond, with that huge woooossshhhh, fallowed by the tires crirping doing into seccond and the look on the faces of a neer buy car full of highschool kids in thare honda with a loud ass intake and a ebay mufler welded on.


but on to the other part..
you were talking about tightening it to whare it flutters a little bit then blows off. is that ok to run it like that long turm on a stock turbo? BECAUSE THAT SOUNDS SO AWSOME!!! im geting all excited just thinking about that sound.

[g6civcx]

A BOV may not add to performance, but a leaky one will make the engine run poorly.

I run the SARD R2D2. Very good quality and great price.

Whichever brand you choose, make sure you check with the Zilvia sponsors for better deals.

[JVD]

If you're on a stock t25, who the fuck cares about compressor surge? Those things are practically disposable...

[!Zar!]

When running the ssqv, there are two allen screws that hold the cover on.
Once you remove the cover, there is a chrome cap. Remove that cap and you don't have to listen to the screech. You have just fixed the only flaw with this unit.

If you pick up a recirc kit, that will also elimanate the sound.

[Silverbullet]

The top end turbos have vents around the outside of the intake that are specifically engineered to eliminate the need for BOV's, because as was stated earlier, they do NOT improve throttle response, they deaden it.

can you explain more about these vents?

[Jamison182]

Get a Tial. It will be the last bov you will ever have to buy.

is that the only reason you drive a turbo car? to show off your blow off valve to a bunch a ricers? haha..

[Bay_Area_sr20det]

you wana buy me a new turbo? because i cannot afford a new turbo, expecialy on a dialy driver.

is that the only reason you drive a turbo car? to show off your blow off valve to a bunch a ricers? haha..

no i would drive a bright greed turbo honda if i wanted that. my dad owned a suped up 240sx and he reciently died so i decited it would be best for me to get one.

[trsilvias13]

The ssqv from hks is proven and i rarely ever heard bashing on it. I would get that, but it does have that hks desintive tone. I run a blitz dd right now because it is free.

[woodchuck]

i have a blitz and i'm on my second one. i broke the first one cause of regular wear and tear. IMO this bov sounds like a public bus releasing preasure. its loud and ugly. i just like it cause its loud.

just go with the hks cause the way i see it the blitz = to the greddy.

there's a pull type, and push type,
but either bov's mentioned are good ones,
some even run ebay ones with decent results...

this is good info.

Is the ONLY reason you want to have a turboed car is so you can make a little noise when you let of the pedal; You know that's when the blowoff valve will sound off, not when you push the clutch in and shift.

Don't be a ricer acting like your car is the shit. Nothing is worse than some kid with a stock sr thinking he's all that.

And you're in the bay area, sr/ka/rb cars are a dime a dozen.


Looks and performance is what makes a car, not some highschool kid thinking he's the shit with a dirt old car that is almost as fast as today's oem cars.


What you should be doing is reading on how to recirc a bov instead of wondering how cool it will sound.



With that said, You've just had a reality check by me.

[Bay_Area_sr20det]

hahaha, you dont know me at all. the car is sentimental to me. not to show off. and its gona not going to vent. and who said i want a turboed car for the sound. if i could i would be happy to have a small v8 in my 240, but i want a daily driver that has good gas milage that i can have fun in the mountian with. if you really want to talk crap about me/my life. then come down to my house and show me why you are better than i am.

Wah wah waaahhh. Cry me a river.

That sounds like showing off to me.

And don't even get me started pm fools like you racing around in the "mountains".

I told you what needed to be said; Even though you should've searched.

Why don't you stop failing at life and pming other members and myself with your e-thugging debauchery and go back to class and learn how to form a propper sentence/paragraph. Because if you keep messing around callin people out, one day your ass is gonna get shot.:D


my dad owned a suped up 240sx and he reciently died so i decited it would be best for me to get one.

But as a positive statement, I'll end this saying that I'm glad you are building your car in respect of your father. Good luck.


:lockd:?

[Jesses240]

I've had ssqv's on my DSM's... loved those... never had a problem with any leaking although i have seen quite a few leak.

+1 for Tial products as well... there bov's rock

ive red very good things about tial. but its a little to expensive for me.

___________________________________________

i also had another question whats the easyest way to weld a bov flange on the stock hot pipe? i was think drill a hole in the hot pipe with a hole saw and then weld the flange. and yes i know its steel.

[ballr858]

nobody likes the greddy type s? i haven't had any experience with any other bov's other than the type s. i was originally gonna go with the ssqv but a lot of my dsm buddies talked me out of it.

[ballr858]

oh btw, if you do want to show off, isn't there some kind of RFL bov?

[sr20newb]

I had the Blitz on my SR20 and hated it...it was just to loud...and caught the cops and ricers attention to much. :rl:

+1 for the RS

[Bay_Area_sr20det]

ya, i think turbo xs makes the rfl, but that stands for REALLY FREEKIN LOUD!.

[ladiesman8527]

i have a blitz DD BOV, but right now im running my Prof BOV. the Prof BOV is ok i guess. it doesnt open as much as the blitz DD under low boost, which i like, but i think its leaking a bit under full load. i dont think the Blitz DD is that loud. my friend's HKS SSQV is much louder.

[Silverbullet]

whys this thread so long? We've established that all BOVs work.

whats wrong with picking which sound your car will make? If your telling me you dont care how your care about how your car looks or sounds at all then your just lying to yourself.

[fliprayzin240sx]

ya, i think turbo xs makes the rfl, but that stands for REALLY FREEKIN LOUD!.


RFL FTW!!!

But really tho, do you really wanna be noticed with an illegal engine in your car. With all the 240s getting stolen left and right in norcal and cops popping people, do you really need a BOV open vented? Personally, im running a SSQ. Its koo, but seriously, it gets on my nerves ever so often cuz itll blow off no matter how high of a boost your at, even at 0 psi.

[Bay_Area_sr20det]

well i opted to buy a ssqv, and i welded the flange to my stock hot pipe and it works awsome, its vented, and for some reason my car doesnt di at all when i stop at a light or a stop sighn, im going to recirc it tomarrow. then i was thinking if thare is anyway to make so my car doesnt feel so slow when its vented. do i need to get a safc to make it run right? or is thare a way i can tweek it to run good without changing anything on the computer?

[viscid240]

I didn't realize so many people were running the blitz bov. I am one of the many running the dual drive version also, I like it alot. The only other bov i had taken into consideration was the sard r2d2 which I believe sounds like the blitz but a bit louder.
