Turbosmart BPV v Forge BPV
 

Besides not being able to get the turbosmart bpv yet does anyone know what the differences are between the two? I see the Forge uses shims and the turbosmart uses springs for adjustment, but anything else different? Thanks for any input on these two.

You can buy it from Streetunit.

what makes you want those over something like the hks bov? just curious because im not sure what i want and trying to see what makes people get certain ones.

Different sounds and different applications.

I know su sells it just wondering why would one by that vs the forge?

its a smaller unit, and requires no modifying. if you have an intake it makes the psssh noise too. dont see why ppl spend so much on a bov that they have to recirculate anyways when this stock replacement fixes the leaks and gives the sound that most want.

I've had both and I have the TS now. I like both. They both work the same for me. The forge has the loud ping sound. The TS has a quieter whoosh sound. If you want quiet, get the TS. If you want the ping, get the Forge.

Forge sounds a good bit more distinctive and louder, and it's closer to looking like stock when you get it in black.

I haven't tried the TS but it's still a piston type valve, it can't be that different by much besides sound and looks.

Forge with MS intake:

Not looking for the ping so I guess the ts is the one.

I do have it on the car. It sounds like the stock BPV with an intake but a little bit louder. Pretty sleeper if you ask me. Driveability its very similar to the Forge but not as tunable. With the regular spring on the Turbosmart I get a little flutter which is normal. I have a ETS TMIC, CS test pipe, CP-E CAI, PG TIP.

nice thanks, whats the diff in tuneability?

with the forge there is a blow off noise but it's not a ping - I'm not sure where that came from but "ping" is not correct

What do you mean by a flutter? And why is it normal?

Turbosmart you only get 2 spring choices. Forge you get 3 springs plus 2 shims in conbination.

On low throttle boost or boost at a higher gear there is a little flutter. As long as its not surge you are ok.

It's me or there is no seal under the turbosmart BPV?

It comes with a separate gasket.

with this flutter are you talking about leaking boost, lagging? sorry im confussed as the what the flutter is doing and how you notice it.

Flutter is when the valve doesnt close all the way and it opens and closes very quickly, its not that big of a problem just slightly annoying. In all honestly if you listen to a lot of cars with after market bpv or bov you usually hear flutter. Non flutter is a quick distinct pppshh flutter you actually hear the valve open and close with a few faint sounds. Youtube it and youll hear the difference.

Anyone interested in buying my Turbosmart BPV let me know. Pretty much brand new on my car for a day. Not that it doesn't work perfect but I got a good deal on a HKS.
It will be worth while for someone from Canada to purchase it from me.

i have the forge and i love the sound. blue spring only with the aem cai and all i get is wooooooosh all day long....... no ping sound of any kind.

pm

for people that have forge with no ping....vids or it didnt happen

Mazdaspeed CAI, ATP TIP, Forge BPV.

that was the worst sound clip ever. do it when your parked....not inside your pocket on the highway

I didn't make the video, I only uploaded it onto youtube for the guy. It really doesn't matter though because you can clearly not hear the Forge "ching".

i have modified my forge b4 using of all things a nylon washer from medieval. (no bullshit) it was roughly the same diameter as the forge shim....about twice as thick and it had a half inch hole in it. I placed it over the forge spring (instead of under like you would the shims) and it eliminated all pinging. oddly enough I didn't like the stock sound so I went back to normal forge ping.

So do you have to service the turbosmart bpv the same as you would the forge?

you cant CLEARLY hear much of anything.

You must be deaf because I can hear the BPV sound and it's definitely not a "ching". The Forge "ching" is one of the most distinct sounds out there.

I've had the Forge installed on my speed6 .. the sound of the "ching" was quite annoying, and to be honest, I didn't care for the driveability with it.. tried all the different spring combinations, but found the on off power transition quite rough.. shifts felt harsh..
Went back to stock.. mainly to get rid of the annoying sound..

Just installed the Turbosmart .. No more ching.. just a nice normal psssh sound.. like others have described, it sounds like the stock bpv, just about twice as loud and a little sharper... although I wasn't expecting much change in performance, the most noticeable change for me was the fact the car no longer "hesitated" when initially leaving from a stop.. with the forge and the stock units, accerlerating from a complete stop was usualy accompanied with a slight hesitation/bog .. the turbosmart completely eliminated this..

thats exactly what im looking for. I only have 1k on the car and it bogs like you described, its so annoying.

you must be retarded because that is a shittttttty sound clip. the only thing i can hear is you fart in the background.

here is what a real clip should sound like:

We want this kind of sound clip but with the turbosmart.

A) I already admitted it was a shitty clip.

B) I already said I did not make the video, only uploaded it for him.

C) I (and other people on 6crew) can hear the blow off sound, and there is NO ching sound for the guy.

Glad you liked the valve chrisyng. We should make a sound clip for them at lunch one day. lol


triplejumper18 - its a pretty low quality sound clip. I hear a little "ching" but i'm not too sure if it is or not because its not audible. But does he have his shims on the wrong side of the spring?

He has tried every combination, and he has even tried his Forge out on other MS6's, and it gave those guys the ching sound.

Has he ever thought there is something wrong with his car?

my point is that its so crappy that you wouldnt be able to hear a ping if there was one. I understand its not your video, but dont come in here saying you have proof, when the proof isnt even definative. The only people I have heard that say they dont have the ping, is people who dont believe that NO ONE'S forge make a ping sound.

the sound clip is not credible and therefore:

quality sound clip or :stfu:

He's pretty sure everything is fine. He used to be a tech for a racing team so he knows his way around the car pretty well.

It could be the ATP inlet that doesn't make it whistle. I'm on the stock inlet and there is definitely a whistle.

However there should be no performance difference between the two unless your Forge had a kinked O-Ring or missing the bottom seal.. they're both piston valves, not dramatically different in design.
