I am going to upgrade from my factory bov one my MS3. I am looking at the forge, turbosmart, and turbo xs (all three would be in hybrid 50/50 mode). Does anyone have any advice, personal experience, or sound clips? (I've already dug through youtube btw...) If I go with the forge, can I put in a different spring or something if I turns out I have the super mario brothers coinbox sound??

Also, this is my first post. I bought my 08 Metropolitan Gray Mica MS3 a week ago yesterday. I wanna hold on to my warranty so I will probably add tint and a sri I can remove for warranty work. If anyone is interested in a moderately modded 1996 Integra, it's for sale, drop me a line!!

Is there a particular reason you want to upgrade the BPV?

(BTW our car does not have a BOV from the factory, it's a bypass valve)

I like the way the turbosmart sounds... I dont have one, but plan on getting one when I got the funds. I tried looking up the turboxs one but youtube doesnt have a good video of it.

Forge isn't a hybrid!

Anyway, I have the Forge. Loved it when I put it on the CX7, so it was a simple decision when I bought the Speed3.(hump)

I'd love to rock the Turbosmart, but no way was I gonna spend as much for a BOV as I was a downpipe and three quarters of a midpipe, lol. I picked up the HKS, decided it was to much trouble to put it together, sold it, and sometime this week I should be getting the Synapse Synaptic BOV.

I ended up ordering the turboxs hybrid 50/50 last night. Hopefully I'll have it installed this weekend and post some sounds, pics, and/or vids. I loved the sound of the turbosmart, but at almost twice the price, I just couldn't do it. I am a teacher (with an open contract) and this week coming up is spring break... so I'm missing a week of pay, you understand.

Why did I get a new bpv? I've heard the factory one leaks and the ms3 will hold upto an extra psi or two. That and, not gonna lie, I love the sound, even if it is a bit ricey (rei)

Just be ready for some drivability issues...even with the 50/50.

Could you explain? i'm looking to get a BOV as well probably the TurboXS as well

50/50. some of the air is still vented to atmosphere. That air is 'metered' in that the car is expecting it to stay within the system, but instead it's being vented. As a result, the car will still inject a certain amount of fuel, but there wont be as much air as is expected, so you run will run extra rich between shifts.

The car will overall just feel jerkier when you left off the gas in gear (due to rich condition again). It has the same symptoms as VTA, but just not as bad. I guess running rich between shifts could also make the cats go bad quicker, but I dunno how much that's really gonna matter. Sometimes you'll hear burps or pops in the exhaust, this is extra gas (from the extra rich shift) ignited or whatever somewhere in the exhaust.

I had the SU Hybrid....but I went back to stock once for fun and forgot what I was missing out on (driveability and smoothness of operation). That's why i sold it..kind of miss the sound sometimes but honestly I would get a full recirc valve. TurboXS does have a full recirc valve too! (You should get it and tell us what you think, no one seems to have it lol)

aaronc7 pretty much summed it up. Yes, you will still run rich in between shifts resulting in drivability issues; long term damage could result to the catalytic converters and your Wide Band O2 sensor ($400).

This was confirmed by a couple of vendors when I was looking to buy a BOV/BPV. I also wanted a VTA or 50/50, but not at the expense of drivability or my engine/sensors/cats.

If you get a piggy back ECU, then you can tune for the VTA or 50/50.
A few owners out there still run VTA or 50/50 regardless of issues...

SO is a BOV a waste of money?

03-20-2008, 04:08 PM

if your car is stock or near stock then ya. Get an SRI first, you'll be able to hear the stock one really well.

I don't plan on doing more than a CAI a rear motor mount and I thought a BOV. So it sounds like a waste not sure what a SRI is but I will look into it.

lewisb01

03-20-2008, 09:38 PM

I was just on protege garage website and there is a stop sale on mazdaspeed CAI, does anyone know why? and would I be better off getting a full CAI or the shorter cheaper SRI?

If i'm going to spend money I want most performance from my money, does the CAI give me more ponies than the SRI?

Sorry for the stupid questions.

AutoXRacer

According to dyno tests, the MS CAI has yielded slighty more horsepower than the SRIs...
(According to Mazdaspeed the MC CAI yields 25HP at the crank)

Mazda announced a stop sale on the MS CAI due to some owners having a lean idle code (CEL). Mazda is going to continue selling the MS CAI, but it may now come with an ECU reflash...all this is from the grapevine though at this time...

I've had my MS CAI on since 11/07 and I've had no issues...
The few that have had issues are owners in extremely cold weather...

I was talking to a friend of mine today who's a mechanic, does regular maintenance, but performance isn't really his thing. Showed him my new turboxs 50/50. Since I had taken off the cover next to the airbox, he claims that I will end up sucking water when it rains. Does anyone have any validity to this claim?? Pics are up btw.

Ive been wanting an MS3, and I was thinkin the first thing i'd do was to put a BOV on it, I loved the turbosmart BOV sound from youtube, but if you guys are saying it'll cause probs, then i wont get one whenever i buy the MS3. :( But i did plan to go SRI - so if you can really hear the stock BPV then, that's all i'd be after - everyone loves a loud, mean-sounding turbo! Very intimidating!

hilmar2k

....everyone loves a loud, mean-sounding turbo! Very intimidating!

There is nothing loud, mean sounding, or intimidating about our turbos.

Even with an SRI, you can't hear the turbo at all, just the sucking sound of the air going through the open filter. Far from intimidating.

04-11-2008, 09:53 PM

well, why is it on allllll these youtube videos i can hear the turbo and the BPV very loud and clear?? look on youtube at the Cobb SRI, or better yet

http://www.youtube.com/watch?v=uY6Z9ITgYIw
http://www.youtube.com/watch?v=_2mFQR0tdPw
or
http://www.youtube.com/watch?v=Rmsh_oVujOo

all of these are stock with intakes..

That's not the turbo. As I said, that is the sound of air being sucked through the open air filter. The turbo on the MS3 is the size of a cupcake, and is not capable of making significant noise.

EDIT: Not sure I understand your comment about all of those being with stock intakes, when all of those videos specifically mention either a CAI or an SRI. Hmmmmm......hardly stock. Either way, that's intake noise, not turbo.

mordant80

04-11-2008, 10:46 PM

Umm, YES you WILL be able to hear the stock BPV with a short ram.. That's all I'm saying, not gonna argue with anyone.

04-11-2008, 10:57 PM

The Cobb SRI actually makes the car sound quite nice. Intimidating? Maybe a little if you really rev it up and or punch the accelerator. But yeah you hear the "sucking" more than anything and you can hear the stock bpv which is kinda cool.

Demi

04-11-2008, 11:30 PM

I have the Injen cold air intake, and not only can you feel it but you can sure as hell hear it. The sucking sound when the turbo spools is awesome. I love how my car sounds. As far as the VTA causing drivablity issues and what not you could always do what i did. I bought a HKS with a recuirc fitting. When i wanna add the oh so sweet sound of VTA i can, and when i wanna go back i can, with out putting on the leaky stock BPV. The drivablity issues are kinda exaggerated in my experience, but it is quite a bit smoother on recuirc. Also you dont get the occasional burble and backfire. At least this way you could try both.

well heres the real question does having the 50/50 bpv pretty much equal our stock bpv cause i mean come on it leaks so much its retarded, i hav a forge bpv arriving tuesday ill install it and let u guys know by the end of next week of what i think

Yup, full recirc only. I'm torn between the TurboXS and the Synapse. Decision, decisions....

I was going to go synapse, but its too much of a PIA to go back to stock with that thing and the txs is cheaper.

builthatch

04-12-2008, 02:02 PM

if you want to replace the stocker for fear of leaking, then you have to choose between an all aluminum replacement bypass valve, like the TurboXS RBV, OR, if you want to accentuate the sounds while satisfying the ECU's recirc needs, get the TurboXS hybrid. If you put an open element filter intake on your car, you will hear sounds anyway, even with a stock valve or replacement full recirc bypass valve, so might as well make the most of the experience and get the hybrid valve.

The hybrid valve won't cause any issues whatsoever.

The forge bpv is a good choice for a stock replacement.You may not like the sound tho.

I hear the turboxs hybrid is a great bov to replace stock bpv with and sounds great too.

chacon101

04-12-2008, 03:35 PM

So does anyone have a direct replacement for the stocker BPV that they can provide any suggestions on? I have the MS CAI and if the stocker is prone to leaking, I just want to replace it with something that holds boost better but works in the exact same way.

hey i'm new to the whole mazda thing and just purchased a new mazdaspeed3 2008 and i would really like to purchase a TurboXS Hybrid, but i was searching to buy one and all the infor says 06-07. I was wondering if anyone knew if it will also directly fit my 08? i just didn't know if all the engine stuff was the same? Thank you.

Bought the "06-07" for my 2008, fits perfectly

On a side note, talked to Chris from SU on the phone, great guy btw, he said the only differences from 2006/7-2008 are so small that most people will never know, and it definitly won't make any difference for the aftermarket parts you buy

Kinda on topic so here ya go, i just set up my HKS for recuirc and the "fluter" problem gets worse, and there is no way to adjust it other than finding a softer spring somewhere. HKS doesnt make one that i can find. Its a very well constructed peice and while im sure it would be fantastic on many applications i dont think our car is one of them. It should be noted however that there was no flutter or problems what so ever untill i installed my intake. I love it in VTA, but our cars like recuirc.

I bought the Turboxs HBOV as well. Also, put 4 washers in there. Only had one backfire under heavy acceleration. Mods are below...would the backfire most likely be from the new BOV? Or from the DP and MP? Or is it because of a combination of both? Not that the backfire scared me or anything...shocked my dad though! TEHEHEHEHE!

Oh yeah...Turboxs HBOV sounds amazing! For those that are considering :)
