I disagree.

How will having the bov after the IC make it more efficient??
I have always tried to locate bovs before the cooler whenever possible, this will help intercooler efficiency.

 

just put one on before intercooler and after like i have twin apexi

 

The only thing I have noticed about this statement; is the instructions for "most" BOV say to put it within 12 inches of the throttle if my memory serves me right. I know nothing about the problems with putting on cold or hot side, but that's what the instructions said on the one I installed recently.

 

There are a lot of theories behind the BOV location. Some believe its best to release the air as close to the throttle as possible (as that's where it stops once the throttle plates close). Others believe its best to release the air close to the turbos (so you don't have to recharge the entire IC piping with air again once you restart building boost).

I've never seen any hard data to support one is better than the other as far as street cars go. However, most turbo charged race cars don't use BOV's at all.

 

Found some more.








Note: the oil on the ground on that last one is not from the FD, it was from my FC!

 

The purpose behind a blow-off is longevity of the engine. As Mahjik states, race cars do not have blow-off valves, as continually holding pressure means better response. but this is detrimental to the life of an engine. So when I state efficient, I mean life of your engine. That's the point of putting one in, right ?

 

nvmyre, Your car is killer lookin!!!

 

Well, it's more longevity of the turbos than the engine. The engine doesn't really care whether the excess charge air is released or not. It's to help save the turbos from air being pushed back once the throttle plates are closed. However, even the longevity argument is a little suspect with the turbos as many Aussie guys have done away with their BOV's and have not had any real issues. To be honest, I'm not sure our stock turbos last long enough for a BOV to make a difference.

 

So maybe I'll disable mine and lose less boost between shifts?

 

So is this a thread discussing blow off valves or are we posting pictures?

 

I apologize. Here's one i'll throw in for taking up your time.



Mahjik, sorry man, I sounded real stupid stating engine, instead of turbo. Thanks for correcting me.

 

You just redeemed yourself.

Where are you in socal? You know StaticX27 right?

 

i'm in huntington beach, ca. yeah, he's a friend of mine and i remember going in with your car to do a lot of fixing up . lot of work was put into it.

 

Pretty new pix

 

nice and clean

 

Nice, My cousin lives in HB... I love it there. If I move to Cali. The only two places Id live would be HB or SF...

Hey Dille,

Is that the Vertex bodykit? Looks very nice!

Also, what are your wheel sizes?
And do you have any clearance issues with the front bumper with speed bumps, kerbs ect??

Thanks,
George.

 

Pretty new pix

What Nose clip do you have?

 

Dille I love what you did with your 7 man.. Super clean, JDM, wingless and unique.. Beautiful car..

 

Thanks, guys

Wheels are: 18x9, think ET is 25 or something. Need spacers for next season.

The bodykit is Final Konexxion and i havent had so much problems with speed bumbs yet. Just need to be carefull But today i ran into some kurbs at the raceway so I need to re-glasfiber one side-skirt and some parts of the front.

 

my car in nor-cal.

San Francisco, CA





Sacramento, CA

 

here are a couple recent pics of my car..kinda dirty and no rims yet but ohwell

 

^Nice. Makes that G35 look like crap

 

Hey Kouki that wouldnt be Winged Deer Park would it?
