Forge BPV doubt

[eliwwjd]

I'll like to know from those who have the forge v2 bpv, is this valve push type or pull type? It's just that on the website it doesn't offer any additional info.

[Djohns]

So what are you doubting?

Probs the blue, two shims.

What is a BPV really? What he's searching for is an deeper meaning what is exactly an BPV.

All BPV are push unless stated otherwise.

@eliwwjd; I really think you're over thinking this, man. From what I last remember I think you said you were running like 18-20PSI boost. For your application, push or pull isn't going to make a difference. I had a forge v2 running 22PSI and had no issue.

[eliwwjd]

Thanks to all of you for your replys. i'll be going with forge finally!! The v2 has been eliminated and now we use the same as the wrx. I know what a bpv is, not looking for a deeper meaning, bpv comes in either push type piston or pull type(like hks) and i just wanted to know what type was forge. push reacts faster than pull type but is prone to leak easier. pull type is slower in reacting but holds boost more efectively than push type. I did my homework on reading and getting informed. Forge confirmed me that is push type. Thanks guys for sharing your inputs.

[WAMBUSHHHH!]

I just don't think on a bolted speed with a stock turbo that push or pull is going to matter much, if at all. Now that's not to say don't try to future proof parts if you're considering going BT but I just didn't want you spinning your wheels on push vs. pull BPVs since again I don't think you're going to notice any difference. Both styles should hold the boost you're targeting just fine.

[eliwwjd]

Thanks buddy for your help. What about a catback, i know there isn"t to much gains just sound but any downsides on this since im stock turbo at the moment

[WAMBUSHHHH!]

There was a thread a little while ago that went through this debate. I'd have to go looking for it. I think the end result was that there are gains to be had by upgrading your CBE. They will be minimal at best but there is more than just sound when upgrading your CBE.

So really the only downside is for the $$ spent per performance picked up, the CBE seems to be the worst bang for your buck so to speak. If sound is what you're after, get a CBE but don't buy with the expectation that you're going to see huge performance gains.

Thanks guy! The reason why im considering cbe is because i want different exhaust sound. So going 3" actually gives you at least some gains, even if they are minimal?
At the moment i have a cs racepipe but i'll be going full turbo back with long dp from cobb. Was wondering if when upgrading your cbe at first before the retune, power in lower band is affected due to not being retuned? or ther is gains in the lower and upper band even if not tuned at first?

Let me ask those of you owners of this forge bpv, finally goy my bov and it came with blue spring installed, and it also came with 2 shims, is the blue spring sufficient or do you guys recommend installing the shims?

[2012FailWheelDrive]

Blue spring 2 shims is the general answer you'll get but go with whatever works best with your setup. Also I'm curious what you piston looks like. I bought my bpv around 4 years ago and just recently got a rebuild kit for it and it looks like they changed a couple things about the piston.

Mine came with the yellow spring installed and no shims. I'm running the blue spring and no shims on 21-22 psi and works fine. The springs seem pretty underrated as the blue is rated 23-30 psi and fully opens under slight boost or almost vacuum.

My piston is the one on the right side in the picture, which i see it has better seal design than previous piston. What has me thinking is that the valve came with 2 shims and they told me on Forge that this was shipped in the old versions. I suppose that with the 2 shims the spring gets tighter but not like red spring.

Maybe this is why people use it with 2 shims.

[eliwwjd]

I need some light here! I'm getting a sword clashing sound dammmm! isn't this sound suppose to be eliminated from this model? Has anybody experienced this with the new model FMWRX3?
I installed blue spring with 2 shims but they recommended me to use just the blue spring but im wondering if this has anything to do with metal clash noise. If this is the case I'll try to return it or re-sell it. Dam this shit is causing me money loss.

[Djohns]

And what was wrong with your stocker?

[eliwwjd]

Well nothing. I was recommended to upgrade from something that is plastic to something that is not plastic and would leak. To be honest, the car is pulling fantastic but that metal ping noise is not doing justice to the valve. I'll probably be taking it out and selling it. Damm!

[WAMBUSHHHH!]

@Djohns; any reason you took exception to my previous comment?

@eliwwjd; what version of the forge BPV did you get? If its v1, you're going to have that Mario coin/sword slash sound. Again, I think you're overthinking this. If you don't like the sound by all means sell it and throw the stocker back on. IIRC you aren't targeting crazy boost and you're still on the k04 so your stocker should be fine. Replace it when/if it fails. Again, for your general application Forge, Cobb, HKS, GFB BPVs will do just fine.

My bad! Never even realized I did that. I'm always on my phone so I definitely fat fingered it.

Hey man thanks for your suggestion. I returned back today to edgeautosport.The only reason why ive been looking into one that's not plastic is the fact of possible leak on the long run due to being plastic. I understand that a bpv is a bpv and any will do but to be honest, the forge performed way better than stock on boost recovery and reaction so maybe that's worth it but no no!!! to the mario coin sound. Dam its a shame on forge because that valve performs excellent.

FYI when i bought my rebuild kit the part number for the v2 valve was FMDVMAZ3S.

Hahaha! No worries, man. Just thought it odd since we're typically on the same page with most things on these threads so just wanted to see. Fat finger strikes again!

I'll be honest, I didn't feel much of a difference between my stocker, Forge V1, Forge V2 and HKS. The only time I felt a difference is when my stocker took a huge dump on me and wouldn't hold more than 16 lbs of boost. If you liked the Forge unit, get a v2. The v2 won't have that mario coin sound.

Where can i find to purchase a v2 sideways body? they are no longer being made by forge. Is v2 pull type? because the piston is sideways like the hks(pull type valve)
I considered the cobb xle and the turbosmart kompact bpv but from experience from edge shop cars and other forums i read, the cobb seams to not hold high boost no matter how much you tighten the spring. So the other one i had left was the turbosmart kompact but this valve has very divided good and bad reviews so if anyone here has it and would like to share there experiences, you are welcomed to share them. I have to wait for edge to give me the credit in order to move on with another model

[Djohns]

Go with a go fast bits then.

Alot of people like the gfb but to be honest that was the first bpv i tried like 4 years back and to be honest i didn't like it because of a weird sucking sound the car made when it had it installed so i sold it. So im kind of picky about purchasing it again and finding the same problem again

[Djohns]

Jesus you're picky haha. Dude in your case you need to stick with the stocker until it fails.

[eliwwjd]

LolYeah, im a 46 year old picky man and sometimes i hate it because i don't find what satisfies my expectations(talking about the valve). I also thought of tial qr but don't know if anybody here has had experience with them.

[Carskick]

Have you considered the Turbosmart?

I was considering one, but Justin Basil says it won't help my RPMs drop quicker between shifts, which was my main complaint. Something I need to research, as my RPMs hang too long when shifting around 3.5-4.5k RPMs with moderate throttle pulls. WOT doesn't seem to have the issue.

But I've heard great things about the aforemention BPV. Thoughts?

Yea as far as I'm aware I don't think we've ever disagreed. Most of the time if I groan someone they said something completely retarded or I just fat fingered it and didn't notice.

It's official you're more indecisive than I was about intakes and I went through a CS stock sized intake, JBR stock sized intake, JBR 3in, JBR 3.5in and then a CS 3.5in.

Here's the thing, a lot of your gripes have been sound related and I don't think you really had any true performance issues. Keep in mind that the mods and tune you're running are pretty standard across the board and with that I don't think you're going to get a night/day difference in response with different BPVs. As @Djohns; suggested, I'd go back to the stocker until it fails because I can't keep watching you go through BPVs. You're wasting a ton of money haha.

If you want my honest opinion, go HKS. I loved mine for a few reasons. HKS is a reputable company. Sure, they don't specifically make parts for Mazda but their reputation is pretty solid, especially their BPV/BOV. The HKS could handle all the boost I wanted to throw at it (which is similar to what you're targeting most likely). The HKS requires no maintenance. I hate having to service a part like a BPV. You can call it lazy or whatever but I just hate having to routinely take something off the car, break it down, clean it, re-assemble and install it. It's just an additional step that can result in a leak somewhere and I'd rather leave things as is once there is no issues. If you're so inclined, the HKS can also be run out of the box in VTA. The only downside is the price and a stupid c-clip that is used to seat the HKS unit into the speed flange. If you're buying used be aware that HKS units are commonly counterfeited so make sure to do your homework.

Just my $.02. I know you're picky but I don't necessarily think any of the BPVs you tried posed any real issue for your car.

haha yeah I saw the groan and was like "shit, did I say something previously that pissed him off?". When I got the notification I had to do a double take because I don't think we've ever disagreed. I mean honestly, I deserve to be groaned though so if you were to say "you're being a dickhead" I probably wouldn't have even fought you on it.

I have a tial qr. Been running it for about 3k now. More of a woosh than anything.

Thanks wambushhhh! for your advice
Yeah I have been spending money and im pretty tired! hopefully I could sort out things
Its the hks pull type or push type?

[WAMBUSHHHH!]

It's a pull. But again, I don't think for your application push or pull is going to make any difference. I've gone through both push and pull valves and never felt any difference between them. Additionally, neither gave me any issues whatsoever. They all held boost and responded the same. Stay with the stocker until it fails and then pick one valve and stay with it. Any of the popular BPVs are going to fit your needs..
