Blow-off valve questions

[Sanala]

So at some point in the foreseeable future, I would like to install a blow-off valve on my 2012 WRX for both performance and for that absolutely bizarre and somewhat attractive sound it makes when you shift. I understand that basically, a turbocharger draws in engine exhaust to give the engine a sexy boost at a certain point, and the blow-off valve is what allows the pressure to exhaust without harming the engine. Beyond that... I AM USELESS.

I do have a few questions though...

1. How much will this help with my turbocharger's performance? Will it help with the slight lag the turbo has in the beginning?
2. What are some trusted brands to turn to for a blow-off valve?
3. Is this something I should probably wait a while to do? (Car has like... 1800 miles on it I think)
4. Are you sick of these motherfracking snakes on this motherfracking plane?

Here's one I am considering for now - CLICK ME HOOKER

Blow-off will not effect your turbos spool time unless its recirc and/or malfunctioning

For it to effect spool time itd have to be a bigass BOV that recircs like 25lbs of boost, otherwise not gonna notice a thing, or if it were malfunctioning, youd get compressor surge, which if youre a picky a**, will effect spool time by hindering immediate boost re-entry after purging.

Greddy is the BOV people typically want for the sound, for reliable performance, and my strongest recommendation, go with a Tial, its what I use

The only thing youll really notice is a quicker and smoother evacuation at your point, typically you reace the BOV when youre running a higher amount of boost so you dont get boost leak, factory divertor valves have softer springs so at higher boost it may begin to open and leak out some boost, they also tend to have smaller flanges so the evacuation is someone restricted and slowed. If youre at stock boost and stock turbo, dun recommend replacing it, the only thing youll get from it is the sound.

But I do have scooby recommendations though, if you wanna get a new turbo for it, the ecu in your car comes with a few locked features, one being anti-lag, youll rape the current turbo with it, but youll be badass and between shifts wont drop out of boost, and when you get a new turbo, get an external waste gate on equal length headers and vent it atmospherically, when you hit boost your car will sound like Odins battlecry

[Sanala]

Hmmms, I see I see. >.< So the factory stuff is pretty much not worth replacing... DX.

Throw as many recommendations as you want XD. LOOOOL that sounds awesome.

Psh, I could practically come up with an entire 450hp street/race setup off the top of my head for that car, but I cant go Subaru xD

[Sanala]

Ohhhh, that's ok. Mitsus are still sexy.

So what turbos would you suggest?

[Crimmy Sun]

Because the Black would be unnecessary, the FP Red, thing spools up like a champ and would have no problems getting you to 500whp

blow off valve noises are for children, I always use bypass valves on my turbocharged cars. talk2hand

Diverter valves are for people who leave their s**t stock, and they also make a BO sound as well, youre aware of that right?

What it does is send the air to the intake manifold, preventing the car from stalling when stopping on a red light, so it's more functional than those ricer BOV's that throw the air out into the atmosphere.

Dude.... That's only if it's atmospheric, blow-off valves can recirc too, like mine, the Tial Q recirc

And what you said would make absolutely no sense, the diverter valve would either be unneeded or should be atmospherically vented, if it's dumping into the mani, you have a MAP sensor, so you can vent it atmospherically and not hinder your engines ability to rev. If its recirc its vented pre-MAF so it can be measured properly. What your thinking of is a type of antipathy that just creates a misfire to keep the turbo spooling

If a turbo car needs help idling at a stop light, there's a problem that's likely related to dumping air into the manifold

Also, a recirc BOV is still loud

Turbosmart and Tial won't steer you wrong.

Oh, and ******** your recirculating s**t. Dumping into the atmo, ftw.
