Greddy Type-S BOV

02 SILVER WRX · 02-06-2003, 09:17 PM

I just installed the greddy type-s blow off valve on my car today with the adapter from enthuzacar.com and it took all of about 5 mins to install and it sounds sick with no leaks or anything.
Alright well i just thought i'd post my opinion of it cause i havent seen to many wrx's on here with the type-s

I have type-S and it produces the nicest BOV sounds out of all the other major brands. Thumbs up.

View Askew · 02-26-2003, 02:52 PM

Nice!! I want the Type-S also.

hollywood_pete · 02-26-2003, 03:52 PM

Any noticeable performance loss (problems stalling, etc)? I had one on my '92 GSX and loved the sound. I just don't want to hurt performance in any way on the wrx.

TKRbeast · 02-26-2003, 04:26 PM

where do you install the bov? i've only had my '03wrx for a few short months. use to drive a turbo civic, now i miss my bov. does a bov even benefit a wrx that is stock only?

narenji · 02-28-2003, 10:56 PM

can't comment on the greddy bov, but i had a 50/50 GFB BOV, but i didn't seen any performance gain or loss. the car felt the same, but for the sound. and after about a month of having it on the car, i even forgot i had the bov, because GFB is fairly quiet. It's just a bit louder than a stock car with the airbox silencer removed. the consensus seems to be that for the wrx, an aftermarket bov is not necessary in an otherwise stock car w/ stock turbo/intercooler etc. if you change the turbo, then maybe it's worth it. the stock bov is supposed to handle plenty of boost anyway.

look on your intercooler--driver's side. you'll see a little valve directly outboard of the throttle body, and a vacuum line going to it. that's the stock bypass valve.

gains? sound.
detriments? none, IMO. one note, though. they work a LOT better the less backpressure there is in your exhaust. yeah i know that sounds weird, but trust me on this.

man... you're STILL perpetuating the myth.

jsmonet, YOU may not notice the performance loss, but there is a detriment to having an atmospheric venting BOV--rich fuel mixture between shifts. This leads to reduced peformance (regardless of how slight)

I think we should bring Shiv's opinion on this (like we did on the other thread):

I suggest against installing any intake kits with any of our stages. You will loose power and/or safety margin by doing so due to MAF misreadings. At atmos. venting BOV won't make the car unsafe but it will degrade drivability and partial-throttle performance.

My 2c,
shiv

Also, check out the results from this search: here

I'm glad you like your BOV and don't notice a decrease in performance. Some very well respected tuners (including Shiv) seem to agree that a BOV venting to atmosphere will hurt performance by a transiently rich mixture in between shifts. If you don't agree, that's cool, but I think I will take their word over yours

As the owner of a ~350hp WRX, I can personally say that the OEM BOV seems to work just fine.

This was posted in its entirety in this thread.

I don't see the point in adding (and paying for) something that will actually HURT performance, but that's just me I guess.

-Bob

jsmonet · 03-03-2003, 02:23 AM

please, oh please, go wank yourself. jesus... seriously, do you think anyone who WANTS a damn blow off valve gives even the slightest care about you saying that?

fine, if it makes you happy, go for it. just keep saying it. i mean, it's not like bullsh** like this DOESN'T give nasioc a bad name... oh wait, it does.

edit: do you have anything better to do than seek out all bov threads to "spread your knowledge" like this? people who already have bov's don't much care what you have to say on this remarkably momentary possibility of a rich condition. sure, keep hunting and pecking for my posts and try to refute all you want, but for ALLLLL the freakin drama on this damn board about these, you would think they stalled cars and blew enginges, rather than produced the brief possibility of a small pop in the exhaust.

dookiebob · 03-03-2003, 04:47 AM

get over yourself dude. I don't look for your posts...

I agree, if it makes you happy, go for it. But I think people should know the truth about what they are buying before they buy it.

-Bob

edit: do YOU have anything better to do than to "spread YOUR knowledge" about BOV's?

02 SILVER WRX · 03-04-2003, 08:51 PM

There might be a very very slight loss in power due to the car running rich between shifts but it is just that BETWEEN SHIFTS so it wont effect the performance it wont help it either but o well

plas · 04-23-2003, 11:56 PM

My Greddy Type-S just came in tonight and it actually came with a full kit from Greddy to basically hook it up as a bypass valve.

DuBBRX · 08-07-2003, 01:21 AM

does anyone know of another adapter that can utilize the greddy type-s BOV other than from enthuzacar.com perhaps a little cheaper?

if you haven't bought one, greddy makes a bolt on kit for the wrx.

gruppe-s.com has a flange for about $10 that matches the stock intercooler flange. contact them, not sure if this will work for your application or not.

Tobey · 08-15-2003, 08:54 PM

also the only *gains* you will get from a bov is the cool sound and the fact that it will hold pressure past 19psi, which i heard may be a problem for the stock valve.

posting what i read a thousand times about the pressure holding deal, don't jump on my ass!!

2002t-wrex · 08-24-2003, 11:57 PM

Just bought the GReddy Type-S (Specific WRX Kit) should be here in 4 days

. Can you guys shoot a vid of the BOV on the WRX?
Thanks

Tur1smoWRX · 08-26-2003, 03:04 PM

Where did you buy the WRX specific kit? I already have the BOV and I just want to buy the adapter kit for it.

Tur1smoWRX · 09-02-2003, 03:23 PM

Evolution autosports for $40 http://www.evolutionautosports.com/ they are not an online store but they might ship **** one to you.

ObsidianRS · 09-12-2003, 03:31 PM

I got my kit from www.subarustore.com (TitanMotorsports). It's the full recirculating kit.

Definately takes longer than 5 minutes to install but it recircs the air (so it'll be quieter but no performance loss).

Unfortunately, I think I have a leak somewhere as I hear a screechy bird/leaky-balloon type sound when the turbo spools up. Hopefully it's a loose hose somewhere easy to get to!

*crosses fingers*

elixirvtec · 09-30-2003, 12:40 PM

I just bought a greddy bov kit for my 2002 wrx. Can anyoe tell me how to install it or send me to a website or forum with instructions on how to install it. Thanks

blkwrx04 · 12-23-2003, 04:38 PM

i have the GReddy Type-S BOV, i've had it on my car for like 2 months now. i installed it w/ the recirc. hose, so its more of a bypass valve. of course, i can't hear a thing louder than a flutter. im gonna plug it so it vents atmospherically cuz i actually want to hear my bov. im also installing injen intake and hks carbon/ti exhaust in 2 days. hopefully it'll work out. but i haven't liked the greddy type-s so far just cuz i can't hear it. when i plug it all should be well though. anyone else feel the same way?

blkwrx04 · 12-25-2003, 02:15 AM

also i was just wondering if anyone knew what i could use to plug the BOV w/????
