Hello guys. I'm planning to be fbo next month and already decide which dp's, intercooler,intake to go. But while reading around here i was convinced that i also need charge pipe and blow off, if i'm gonna run high boost with e85.
So the question is which bov to go. i mean those of you who alredy got bov kits just to say your opinion about the loudest? quality? Active autowerke? or HKs? or TIAL?
Advice please!

All the BOV's you mentioned will be more than sufficient to hold high boost. It will really come down to sound preference. You can easily find videos on all types of BOV's with a quick search (Google magic ).

Synapse

I installed a hks bov and like it...not too loud but loud enough

[triggz]

HKS or Tial are both proven and race cars use them. Tial especially

as i understood almost all bov's cost the same and sound pretty normal!!!
That makes my choice easier)))

You should get Forge DV's. If you want, have them vent to the atmosphere like a BOV:

Sturdy charge pipe, uses OEM style connector and c-clip which I liked. The bov itself is loud, it shares the same flange as Greddy BOV's so you can mix things up. I had to buy an extended coupler and t-clamps for the connection to the intercooler pipe.

Just curious, is there any benefit to a bov (other than noise) over the stock (in good working order) diverters?

Thanks man very useful info. Just to clarify: extended coupler and T-clamps are not included yes? Where can i get it? And is it possible to install without them??

At stock boost levels no. At higher boost levels yes. Higher pressure handling, better throttle response, less lag.
At higher boost levels aftermarket BOV/DV will definitely be beneficial.

Luckily I've always recommended Tial to all my customers when asked.

Our most popular charge pipe /BOV kit sold today is the Evoluion Racewerks, Tial BOV. Usually in anodized black.

+1 Tial. Their wastegates are solid too.

Funny you say that cause I have seen in the past threads about the stock charge pipe cracking or popping off and always thought it was related to the stock DV's failing causing excess pressure at the throttle body when closed. That almost make sense

Yikes, didn't know this. Thanks for the heads up, Jeff.

What about active autowerke vs tial? Quality? Loudness?

I've heard of some DV leaking but I've never had an issue with mine at higher boost levels.

Do you have any instruction on how to do this? I think this is the classiest sound.
