Is it a PITA to keep adjusting it? I would you know when it is perfect?

i have heard the HKS in person for the first time 3 days ago and it sounded terrible, like a bird chirping! It was on a twin turbo Nissan 300ZX.

How about the Greddy Type-S? Sexiest sounding bov/bpv ever made ;) No shims needed just turn the screw at the top to adjust the stiffness

A BOV of one car might sound horrible but on another car it might sound better. I know for sure that I love the type-r bov on a srt-4 but on a boosted 3 sounded like pffffffft

it took a few times of twisting it and some driving it for it to come out perfect. I don't have any issues with it at all. It takes some wear and tear to break it in just like the other bov's do. The spring just needs to get used to your driving taste and boost usage and then its all good from there.

isn't the type-r for 400+ hp? that's what I was thinking. I'll take a video of the type-s on mine and post it up if someone wants to hear.

Really all bov's are preferrence based. LOTS of people like HKS, especially in the MR2 forums, but its all up to the buyer.

So the only difference in all the bpv is the noise it makes? one doesn't hold boost better than an other one? I don't know why forge don't cost as much. IDK... After I see how my stocker holds boost I'm gonna get a bpv just to see the boost difference. Just waiting for my ventpod

yea i wanna know too, if one holds boost better than the other. i'm thinking u get what u pay for. personally, i like the sound of the hks and i'm leaning over direction.

Gosh... which bpv to get. I know my wife doesn't want me to spend a bunch of money on car parts but that is just too bad. People always talk about what a great product forge is. I never heard about turbosmart until I joined these forums. My buddies always talked about hks. It's just too bad that there isn't no modded MS3s in the area. I've seen about 8 different ones and they look to be all stock. Hopefully when I move back up to norcal in 7 more months there will be some people in the area with MS3s

HA, i guessed right :D too bad you weren't any further south ... south would have been able to make you hear the forge in person. Either way, its a personal preference when it comes to bov/bpv and the sound they make. In the MS3 market I think the all if not most of them are pretty decent. I have the Forge on now and it performs well but I'm going to install the HKS cause I'm just looking for something new and it give brownie points at car shows. The Forge to the untrained eye is just another stock piece.

A young fellow who has a very nice True red one runs the Turbosmart and is quite pleased it seems. I am not sure whether my Forge is louder or more chingy though. We had an hks on the Del Sol and it was much chingier than me.

I just don't know why forge cost less than the other bpv? Is it looks? Does it hold boost as well at the other BPVs out there? Is it because you gotta mess with the springs and shims?

I'd have to say, it's the way it was designed and how it functions. They all hold boost better than the stock valve but all aftermarket function differently. That's all I can think of.

Springs and shims do have something to do with the lower cost as opposed to other valves. For example, HKS and Synapse valves are more expensive, but they automatically adjust to all levels of boost. The forge has to be manually adjusted.

The HKS and Synapse valves are also Pull-Type valves, which tend to hold boost better in the long run since more boost actually tightens the seal. I believe the Forge is push-type.

hks has sequential valves

Bonafide_Spd3

08-24-2008, 03:20 PM

So the valve is a rubber piece inside the bpv? Wouldn't it dry rot? So the more you pay the better the product? Or are you just paying for the name? Just like nike

In the HKS it is a rubber diaphragm that expands/contracts...I haven't heard of any issues with dry rot, but I'm not an expert on the HKS. In the synapse synchronic, it is a piston design that opens/closes depending on the boost.

The HKS and Synapse valves are both DEFINITELY better than the forge imho. However, for the price, the forge is a good valve. It all depends on how much you're looking to spend. In this case, more money does net you overall better products...but whether or not the extra $150 is worth it for the difference in quality is up to you.

Not to be a smart ass, I really am open minded on this. I realize Forge is a diiferent or even basic design. But what justifies 150 more dollars. It opens it closes and stays closed. And it opens fairly quickly depending on spring. Just wondering

It just depends on what you are looking for. The forge is an improvement over stock, but if you want the BEST BPV you can get, the HKS and synapse valves are better. They adjust to wider ranges of boost, do not need to be manually adjusted at all, and are pull-type. The forge is great if you want some inexpensive improvements to your car, but if you want to take your car farther and really invest in it for some future gains, the HKS or synapse valve would be a better option.

I later on want to make over 300 whp in my car. That is my future plans for this car. I kinda wish I never got my extended warrenty though because I don't know if I will be able to do this with just bolt ons and not engine internals

You should be able to make 300whp with a couple bolt ons

ndedomin

08-24-2008, 08:13 PM

+1. With exhaust, intake, and some good engine management, you'll be getting pretty close to 300. You may need a few small add-ons after that, but you can definitely get 300whp with bolt-ons. At those numbers, you'll be fine with either the forge or the hks (or the synapse valve), but personally, imho, I would always go with the hks or synapse over the forge. It is more expensive, but you get what you pay for.

If you like the hks, get it. Trust me....you won't be disappointed. Just make sure you get the bolt-on kit from Protege garage. It is by far the easiest to assemble that I have seen.

Greddy works just as good as the others, they each make their own sound. If you look on youtube for the gredy type-s the sound is addicting so you'll probably like it. I need someone to tape a driveby for me to show what this valve sounds like.

I also had the ebay imitation greddy which i think i posted the link for earlier. $60 for the valve and flange and works like a charm! Just makes a different sound than the real greddy so i got the real one for the whistle sound it makes. To me it all about the sound, as they all pretty much do the same thing and work just as well

UHATEIT

hmmm. it depends on the car. Some videos are deceiving. But I heard an HKS on a twin turbo 300Zx the other day and it sounds like a bird chirping to me. But the Greddy type-s on my car it a very high pitch whistle.

I don't have anyone to take a driveby for me to show you my type-s sound. But this is a great example of how badass (or annoying depending on how you like things) of a Greddy Type-S on a Mazdaspeed Miata. This thing is freakin loud as hell:
http://www.youtube.com/watch?v=IPOEjAnQIlI

Otherwise if you don't want the "real" type-s you can get the ebay knockoff which is actually pretty nice too and cheap. It makes a completely different sound tho, but I loves the sound of the fake one too. Its like a more powerful version of the stock one. Here is a video of that on mine before I bought the real one later on just for sound purposes. It's louder than this in person:

That doesn't sound bad, sounds alot better than the forge. The hks kinda sounds like our stock bpv. But probably alittle bit louder huh?

UHATEIT

08-26-2008, 03:01 PM

The HKS makes the bird chirping sound. The first video is the REAL Greddy Type-S and gives you that very loud whistle (sounds better than HKS by far IMO). The fake greddy I posted my video of above is the one that sounds like the stock one but much much much louder. If you have an intake your stock one will be louder, but the fake greddy will make it pretty loud.

Yeah, haven't seen the movie in a long ass time though. Don't remember the sound of the bov either. Your probably the first one I saw one here talking about the greddy. Everyone else talks about forge or hks. Since I've joined I've never seen anything about the greddy type s. Sounds hecka cool

i know forge and hks are good, but I believe its more of a "hype" with those right now. Because the forge is MS3 specific and a lot of people have them so its more hyped. The Greddy type-s has been around since the early 2000s, I had one on my 95 eclipse GS-t back in 2003 and loved it then and could nto get the sound out of my head for years and had to have it.

TRUBOOST had it on his, and he's heavily modded (21psi i believe he runs) But others do as well. Lestat13 also has the type-s on right now and him and i talk back and forth. He really likes the sound of his. He also has the turbo xs 50/50 hybrid which is a great valve and popular as well (for good sound). PM lestat13 and he will tell you the benefits of each if you like.

Even at the cheap prices type-s knockoff it works well and holds up nicely and was $60 for everything. which is 1/3 the price of the turbo xs and less than 1/2 the forge price and probably 1/4 the price of the hks.

haha, yeah... I think my kid will like the noises as well. Dang, good thing I got some time to think about which valve I want. I do like both the sounds they make. I just looked up some stuff on the greddy, you have to order the different parts for the recirculating fitting and the flange? They both come out to be around the same price. Uhateit, yours was in recirculating right?

yes mine is recirculated, You dont need a recirculating adapter tho. The stock recirculation tube will fit over the neck that sticks out on the side like I was showing you. These are the items needed:

ATP SU adapter flange for the MS3, $30 shipped from SU

Or if you choose to buy the REAL Greddy, this oen is about $100 shipped for this valve and gives the loud whistle from that Miata video:
Installs just the same as the other one with the same adapter

Regardless of what valve you choose, just make sure whatever brand you get has the neck that sticks out on the side so you can recirculate the valve so your car runs better.

I want to run VTA because I like the sound :) I just don't know what is involved with a tune, what it actually does, where to go, and how much it costs, how long it lasts, any negative effects, will it need to be changed before a dealership visit or cause you not to pass smog?

Thanks for all the info guys. So the recirculating hose goes up to the area where the air would vent to the atmosphere? How do you keep the hose from coming off there? I saw they sale recirculating fittings for them

the neck that sticks outwards is where the recirculation hooks up.

i found this online of a diagram of connections:
http://www.mkiv.com/techarticles/hks_race_bov/hks_bov.jpg

the stock hose comes with a black crimped clamp, but on the type-s the hose just stretched over the open neck

Bonafide_Spd3

08-26-2008, 06:35 PM

so where the atmosphere or turbo inlet is where the recirculating hose hooks up. I think the greddy does sound better than the hks now. After watching a couple more videos

08-26-2008, 06:49 PM

Atermarket bpv holds boost better than the stock valve. I'm waiting to see how much my stocker one holds once i get my ventpod. I thought i would get my boost gauge today but I guess not. I also like the sounds of the aftermarket valves

john blutarski

08-26-2008, 06:58 PM

The improved response and ability to hold boost better at higher rpm was definitely noticeable in my Forge BPV. They serve more purpose than just noisemakers.

UHATEIT

08-26-2008, 07:00 PM

so where the atmosphere or turbo inlet is where the recirculating hose hooks up. I think the greddy does sound better than the hks now. After watching a couple more videos

yeah, i just realized the diagram wasn't saying recirc on it. But yeah thats the one. If you take your stock tube off it will slide right onto that inlet. Like the other guy said, running vta makes the car have bad mpg and poor idling/stalling. its better to recirculate it. The car needs to read the air that blows off to adjust fuel n all that. But if tuned you can vent it and get the really really loud sounds.

Pardon my unintelligence but does BPV/BOV have any sort of performance/saftey gain for the car? or is it just to be loud and showoff?

As far as performance, if you floor the car and have a boost guage with your stock valve on there you should see it start to drop in psi as you are driving at wide open throttle, thats from the stock one leaking. But with an upgraded one, if adjusted properly will "hold boost" instead of allowing it to slip out. Basically you lose the top end power. Sometimes even with the stock one it will leak under low boost prematurely, and the response of the bov acting as such can affect the driveability of the car and the car will not run as smoothly.

Safety wise, the stuff mentioned above can also affect the life of the turbo. So in a sense its safer on the turbo to have a valve that works properly so the turbo doesn;t have to work harder.

But sound is always a fun plus to add to it :)

Whats the difference between the greddy type s and the rs?

Bonafide_Spd3

08-28-2008, 11:53 AM

So the only difference between the two is that the type s has a 38mm valve and the type rs has a 40mm valve? And the type rs has a more of a psshhh sound? I think they said the rs is just a bov and doesn't recirculate? Correct?

lestat13

08-28-2008, 01:20 PM

The type-s gives whistle sounds, and even in recir mode still whistles. At full boost and fast releases, you get a whip crack sound with the whistle. I love mine, loved it more vta, but I can live with recirc.

The GReddy type-rs is more of a mopar bov sound. It gives you a very nice "air exiting" sound. Where the turbo xs 50/50 has small holes and gives the whip crack sound, the rs will give you the whooshing sound. Actually, this one also sounds really really good recirculated. When I eventually get tired of the type s, I will probably buy an rs.

UHATEIT

08-28-2008, 04:54 PM

Whats the difference between the greddy type s and the rs?

The type RS gives the whoosh sound as opposed to the pssssst sound like the type s

you CAN recirculate the r/s tho, bot for that one you would have to buy the adapter and you twist off the blow horn on the side and twist on the adapter, which gives you the neck that extends outward so you can fit your hose over the edge. But the type-s already has the neck that sticks out as opposed to the horn, so you don't need an adapter:

here is the type-s connected and recirculated, see the stock tube would go over the neck like this one in the picture:
http://www.roadraceengineering.com/parts/greddy/greddy-stypebov.JPG

the RS has this little horn on the outside, that you remove and put on a straight neck to recirculate it:
http://www.turbohoses.com/greddy_type_rs.jpg

so for the RS you have to buy this fitting to recirculate it and screws on in place of teh horn:

Here ya go. Just finished single spring mod and that is a real greddy-s in recirc. I knew it was too loose when after it would blow off I would get a moderately loud "blowing over the top of a bottle" sound. I tightened it just until I didn't get that sound anymore. Holds boost like a champ, spools up fine, and no issues. Same as UHATEIT, it is getting louder as it breaks in. The sound is like a mix between the GReddy type-s blow off (vta), an HKS or forge style clang, and sometimes gets the whip crack of a 50/50 turbo xs valve. Hey, I am a music teacher and I love sounds, get off my back ;)
http://i56.photobucket.com/albums/g165/lestatthirteen/0828081835.jpg

that looks great! I still need a drive-by video of yours! I'll make my wife take one for me. Yours is tightened about as much as my fake one was tigtened. I was thinking the "looser" it is the louder the whistle. But the tighter it is the quicker and tighter the sound but not as loud. We'll see I like my setting now but I might tighten it to see how it performs.

if you look up a few more posts and see the one of my real greddy installed, thats how it looked with the screws turned 3 times. But up further in the thread the pic of the real one on the counter is how it was when it was just touching the top of the spring and no turns. Yours looks like 6-8 turns or so from first contact

Everytime I take one on my phone, you always hear air but never whistle. Eventually I will find someone with a camera that can do video and sound or something.... :\

My camera = the sex

Where in MD are you? I'm always going up to Rockville and would like to hear the GReddy in action ...

That would be prety pimp to hear some sound clips of the rs. I think the type s still sounds really good. I'll probably end up going with the type s. Thanks for all the info everyone

I live nearish Columbia, but I work about 45 to an hour away in Gaitherburg, but grew up in the college park area where all my friends live and where I work on saturdays. Sporadic enough for you ;) Coolwhip, we should meet up sometime, Rockville sounds good. I usually get off work around 7pm on Saturdays, so like an 8pm meet would be perfect. The s in recirc sounds surprisingly good!!

UHATEIT and I both got ours used. I think he hit up ebay and I got mine from craigslist. they stopped making them a while ago so you gotta grab one second hand.

uhateit where did you order your greddy type s bpv at?

the fake one with the whoosh sound was off ebay for $30 shipped

I found my real type s with the whistle off craigslist off a guy in Tacoma, Washington for $100 shipped. There are a lot of them out there for about $100 shipped. Of you can go check ebay and they have real ones there too. I found the nicest one that I could, only one tiny knick on it, otherwise its perfect.

Like lestat13 said, it sounds great even recirculated. I ran it VTA to work one day just to listen to the loud sound, but the car stalled 4 times and i got a CEL from it so I recirculated it. If you have yours adjusted right and it wears the spring in after driving around it makes a nice sound! Mines almost as loud recirculated as it was VTA after the spring has broken in after driving it for a few weeks.

here is one on craigslist fror sale:

these guys are sellin them, i contacted them from craigslist:
jaime2008@netzero.com

I still need to have someone record a sound clip for me to post up

I thought they were about the same as far as volume goes, then I went vta one night last week and capped the recirculation tube. Maybe it's because its facing down instead of up, but it was about 4x louder and I could hear it echoing off the asphalt down the street!! This was also just over a week since I did the single spring mod and tightened it up a bit to compensate.

Anyone with this valve, btw, do the single spring mod. I didn't quite understand why, but it makes it hold boost faster, release faster, and driveability becomes easier.... especially when you add in the fact its now a bpv instead of a bov.

did you put it back to recirculate again? or are you still running it vta?

I put it right back to bpv..... only ran it for a few minutes to show a friend. vta runs like shit compared to recirulated. I was in denial before, dont do it

That sucks they don't make the type s no more. I've been looking for them brand new... And no luck. I don't want to buy a bpv that is used. Sucks the type rs doesn't sound like the type s. Don't know what I should do now

the one i bought was used for 500 miles on an rx-7, looked almost brand new. Just have to try and find one.

All the bov's will work the same for the most part, the type-s just gives the best quality sound. The fake type-s on ebay sounds just like the real rs sounds

there is one 30 min. away from my house for $50. I'm sure it is crap though since they are selling it so cheap

30 minutes away is not bad! Ask him to email you a picture of it or go check it out. Even if it looks bad it's probably still in working order. I almost bought a used one in bad condition for $60, maybe you'll get lucky!

Remember you need the adapter flange as well to mount it. It's an easy install very fast and easy to do

it's not on there now... Shit

lestat13

09-03-2008, 08:53 PM

adapter flange AND reciruclation tube cap if you are running vta.

and mine was $100, but some people don't know what they have. My guy had it on his talon when he bought it and wrecked the car.

I did!! Looks almost flawless and works perfectly. If you do get one and it doesn't work properly, you can buy authentic replacement type-s diaphragms right from greddy, they are about $50

UHATEIT

09-03-2008, 10:46 PM

yeah man even on ebay they sometimes go for over $150 used! They are a higly desirable bov due to the rarity as they are discontinued, hence finding one new is almost impossible. Crappy conditioned ones on ebay I have seen for like $150 or so plus shipping.
Craigslist is the best since you can find someone who doesnt know that they have like lestat13 said. Someone selling one in mint condition for $100 shipped could honestly get $180 for a great conditioned one or even over $200 on ebay.

SNAp you only paid $100 for yours too? I thought you paid more than that. Either way good deal if you got it for $100. Definately a sweet ass bov!!

after all these pages we should post a "greddy type s" thread, since this thread was supposed to be about hks vs forge haha

naw i was meaning I should start a thread all about the greddy haha. i have my own thread about the fake one. But I think mods are the only ones who can change thread titles.

Keep checking tho. go to craigslists all over the country til you find one with pics and in good condition. The day i bought mine i found 10 for sale for $100 shipped. The jamie guy i emailed about earlier has a mint one for $100 shipped

Bonafide_Spd3

09-03-2008, 10:59 PM

So he has one right now for $100? And if there is anything need to replaced I can just go to the greddy website to get the authentic replacement type-s diaphragm

Bonafide_Spd3

that guy had one for sale 2-3 weeks ago when i bought mine. i deleted his email with the picture in it. I had already paid for one from a guy in washington. They should all work fine. I am not familiar with the diaphragm things. I know ehn i took mine apart to do the single spring mod (which makes it louder and perform better) it was in perfect condition.

Well I installed the type RS today. It holds boost great just like my Forge but its too quiet for me so I'm sticking with the Forge. The Greddy is just a bit louder than stock (I only used it in full recirc mode) and makes more of a whoosh sound than stock. This valve I think is perfect for anyone that wants the performance of an aftermarket valve without the noise.

I have a for sale thread up for the valve with install kit if anyone is interested.
