Loudest Recirculated BOV

2000RS-Turbo · 09/18/2009, 12:35 AM

Well ive search high an low on every site i know an every "which bov is the loudest" thread is about open vent bov's or they say no recirculated are loud. All i keep reading is turboXS RFL but that doesnt have a recirculating option. Im thinking the hks ssqv will be the loudest recirculating as its the loudest bov i can find that has a recirculating option. Everyones opions are welcome(on which recirculated bov is the loudest). Vids would be great thanks

The Greddy something is pretty loud if I recall. ssorry I'm a lil drunk.

here you go lol
why do you want that loud of a BOV??

Fake Turbo Blow Off Valve Sound

A couple guys in my local car club use the greddy rs's and IMO they sound very nice recirculated. Then again, I like a subtle hint of power over something that screams "ricer over here!".

agreed granted mine isnt the quietest but my turbo is screaming lol but sounds good i have teh HKS SSQV

go check out my video i have of it in my build thread. jsut a quick vid

Turbo XS does have a recirculated option and it's the H34. However that BOV is crap.

Your best bet all around is the HKS SSQV, it's loud even recirculated and functionally it is the best BOV you can buy.

johnsgalant · 09/18/2009, 09:48 AM

hks ssq doesnt sound loud and its way different when recirced -- sounds like a weird type rs greddy.. A greddy type S is very lound when recirced it almost sounds like its not recirced and its the loudest ive heard.. You will not get a whistle from the hks with the recirc fitting..

catch-me · 09/18/2009, 11:09 AM

I drove an evo with a turbo xs bov and it was loud as hell, i found it very annoying and ricery. I personaly wouldn't want a loud bov

Ken · 09/18/2009, 11:11 AM

Just some more food for thought.. I noticed that recirculated BOV "loudness" is increased when you run a 4" intake pipe as opposed to a semi-stock intake.

Steveodotcom1 · 09/18/2009, 11:22 AM

You'll get sick of the BOV after awhile. It sounds cool for the first few times when you drive it, then you just want to try and cover up the sound.

I've had BOV's for about 6 years now. I don't get sick of it. Granted, I have a HKS on my MR2 and since the engine is behind me I don't hear it as much as the person driving behind me does... but I personally like it. Rice or not, I don't care. I really truly do it because it's something I like, not to let everyone know that my turbo car is turbo.

2000RS-Turbo · 09/18/2009, 02:27 PM

im trying to find the loudest recirculated bov not peoples opinions on wether they like loud bov's sorry but that ahould have its own thread

. Back to which is the loudest recirculated bov, we've got two nominee's so far the greddy type S and the hks SSQV. But which one is louder?

catch-me · 09/18/2009, 02:43 PM

if you are looking for loud bov, the turbo xs is loud as hell and i guaranty that on of them is recircuable cause I looked at it. Get one and then go street race with your rice.

2000RS-Turbo · 09/18/2009, 02:54 PM

actaul rice would be a fart can, a turbo an loud bov is not. And the only turboXS that is reliable from what ive read is the RFL that cant be cant be recirculated, can it?

Chato · 09/18/2009, 03:18 PM

Get the HKS SSQV.

2000RS-Turbo · 09/18/2009, 03:36 PM

thats what im thinking

LukeH314 · 09/18/2009, 03:47 PM

Turbonetics Raptor

viking51916 · 09/18/2009, 05:37 PM

i had the HKS SSQV on my legacy and it was great. i highly recommend getting it.

johnsgalant · 09/18/2009, 05:59 PM

u will not get a whistle with the fitting the hks needs to be recirced with -- just food for thought == so if u want the hks whistle it cant be recirced -- a friend has the recirced hks and there is a night and day difference to the sound..

Ithinkyou · 09/18/2009, 06:41 PM

Id grab a greddy type-s again. Although i found myself switching back an forth between that an a stock evo bov because it drew unwanted attention at times.

2000RS-Turbo · 09/18/2009, 09:35 PM

On the hks site they say you dont need to recirculate it because its not open when idling

gtseclipse · 09/18/2009, 09:38 PM

I have some friends here that tell me the loudest theyve had is the SSQV, but idk how many they have to compare to

johnsgalant · 09/18/2009, 10:46 PM

at idle u will survive but if ur boosting and suddenly let off u will most likely stall.. My friend had a weird idle and stalled when he left off sometimes.

XwP1ayawX · 09/18/2009, 10:57 PM

I enjoy the sound of my RS vented. I'm in the process of rebuilding my head since it injested the screws off the butterfly valve. When she goes back together she'll be recirculated. I like the noise, but the turbo spool is terrible, recirculating helps keep that pipe pressurized.

2000RS-Turbo · 09/19/2009, 12:08 AM

im trying to find good vids to compare wat the differnt bov sould like but there are too many variables, different psi, engine size, how loud the muffler or engine is that is masking the bov.

2000RS-Turbo · 09/19/2009, 12:13 PM

what about a dual bov setup?

WTF? I'm sorry but I'd been more concerned about the functionality of the BOV than its sound. Now you want to have two BOVs just for a cool sound? That's dumb. My Greddy type s sound good recirculate but that is not the point.

THIS IS NOT A THREAD FOR WETHER OR NOT YOU LIKE LOUD BOV's OR NOT!!!! IT's FOR WHICH ONE IS THE LOUDEST!

can you pick a BOV already you only have a few options that are good but anyways good luck with your adventourous dual ricer BOV.

Turbo XS RFL is the loudest imo

2000RS-Turbo · 09/19/2009, 01:19 PM

better a loud bov than a fart can which every car has.

thahnic1080 · 09/19/2009, 01:33 PM

Do you mean dual port bov? Where its half recirculated and half vented. I believe with those you can adjust the loudness for your liking

Fair enough. But you are talking about adding multiple BOVs to create a cool sound and that mechanically is dumb. You needed to be called out on that one.

2000RS-Turbo · 09/19/2009, 01:38 PM

Ya dual port, what about two differnt bov lol. saw them on ebay when i searched for dual port bov

repforenzo · 09/19/2009, 02:13 PM

There are better options if you want a nice BOV sound. Like using a GM MAFT and venting into the atmosphere.

Venting to the atmosphere is a bad idea.

Did you read what I wrote? You have to convert to a blow-thru setup with a GM MAFT. It works perfectly.

Never get a SSQV blow off valve on a low boost app.. they ruin turbos very quicly... I had a greddy on mine and it was very loud..

2000RS-Turbo · 09/19/2009, 02:50 PM

I know i could get the gm maf an then open vent the bov but id then have to retune, this is why im looking for the loudest recirculated bov. so it seems for the loudest sound an function the greddy type S is the best?

Fergie · 09/19/2009, 04:07 PM

yeah i would get the greddy plus its pry the best to no compressor surge your turbo

D0M · 09/23/2009, 08:59 AM

turbo xs is the loud as hell

tauzins · 09/23/2009, 10:06 AM

ssqv hks is usually one of the loudest ones...

Ithinkyou · 09/23/2009, 05:03 PM

So 3rdly my main oberservations are:
Recirc setup=
-lower/more consistent boost during high throttle
-steady idle after high/low throttling
-iffy airflow

I see this day to day but i can hear it venting while fairly loud flooring it. My theory was as the load backs off the vaccuum comes back as the boost drops off and opens the the valve just a bit. Venting boost back into the initial intake stream.

here an example of what i tend to hear often when driving around recirc'd... Vent-quiet-lil whistle

VS

VTA/ST setup=
-higher peak boost
-less consistent boost during high throttle
-soso idle after high/low throttle
-ecu recovers dropped idle
-high speed(75+)airflow sucks

VTA! Note how you can witness the vaccuum toying with the valve. Which equals sucking raw unmeasured air in light throttle situations. You can hear the idle drop a bit.

This setup is alot more fun to drive around with, and turns heads too. Its pretty hilarious looking at some of the reaction faces. On to the observations. WOT off a light or at the track its fine, and is hella LOUD!!!

Now holding a freeway speed with part throttle you can hear it wooshing open and closed. Building an venting boost... basically creating ripe boost leak/knock conditions

If you floor it right quick like in 1st an then stop soon after. the idle will drop to the 750s an correct back up to the 900s.

here an example of what i love to hear when driving around VTA

The bov was located venting face up right next to the TBThis is as loud as it got. It was crzy loud in tunnels too. Id pick this over an ssq because of the compressor surge tendancies with the ssq
