Turbosmart Dual Port ; Good Alternative ?

[cobrAA]

Hello,

I'm planning to boost at about 25psi. I wanted to replace my BOV with the Turbosmart dual port ( at low psi, it recircule, at high pressure, it will open up and vent it for a sweet sound)

Or should I recirculate completely the system? I heard a recircule BOV will elimate the stalling issue at low rpm but from what I read, the oem bov hold its pressure better so you are always on-boost between gear.

Will I really feel that extra performance giving by a recircule BOV or its negligeable ?

Thank you very much for your input as I never droven an OEM setup and don't know how the boost/pressure feel.

Dual port means, either recirc OR atmo.

Not both at the same time.

Fitting a BOV for "that sweet sound" is for dickheads.

Women won't come running when they hear it.

So THAT'S what I've been doing wrong all this time?! Damn.

Better change to the flutter sound, that HAS to pull the chicks right??

... On a serious note, if you dont want the stock BOV, upgrade to GTR spec (if you dont already have one), or recirculate the Dual Port. I actually use a dual port recirculated.. Looks pretty

Why don't you just go with the proven stock GTR setup?

You know it's good... Not really sure why you wouldn't then use it.

Well.. it was made for 13psi.. not 25psi.. Not sure if it will hold up and honestly not interesting in doing the test myself jsut to find out I have to re-do it agian because its leaking.

Guess 80% of the skyline owner are dickhead then.. who said I wanted to attract woman's attention anyways? such an useless post.

Are you kidding?

They hold over 30psi and over 550rwkw. Seen it with my own eyes on 3 different setups.

No need to do testing yourself when there are 100s of people before you. There are countless users here all running stock items. Just go look in the dyno thread or search "GTR BOV"

What psi is the stock gtst bov good or recommended for?

Well No I wasnt kidding. I spoke about oem bov at our latest skyline meet and most people were anxious about runing oem over 17-18psi. I will look into it. thanks!

Bah don't listen to them. I bet they've never tried to do it. Just like people saying you need a aftermarket FPR and what not for moderate setups... Fact is if the stock gear is working fine - you don't! Save your cash

I ran 24psi/GT3040 through a single GTR BOV on my RB25, it would flutter ever so slightly so probably a needed to be a bit bigger, or go to dual BOV's.

Not much will be lucky if it holds 1bar

The absolute best awesome alternative is part number by Nissan: "14483-05U00"

Your stock bov is recirculating, so why replace it if it works fine? An aftermarket bov will a) get you defected, b) cause stalling issues and popping as it vents metered air c) cost lots of money d) make everyone think you are a dickhead.

So you are basically paying money to sound like a dickhead, get defected and make you car run worse. Seems like value for money I guess?

Holds over a bar no problem.

Plenty, get a GTR bov if you have issues, they will run 30psi fine.

edit: on 18psi with a stock rb25 bov I get a tiny bit off flutter when I back off on a WOT gear change, but it flows plenty for the rest of the time.

Hardly anyone runs an aftermarket BOV these days.

[89CAL]

I run an aftermarket BOV

If your gonna buy an aftermarket one, run full plumback no atmo. You should still hear the noise if thats really of concern, it will just be slightly quieter then if it was atmo

I absolutely agree that the Stock BOV will hold fine, I just dont like the way they sound.

Right now I run 2 blitz and one is seized. And I'm having stalling issue hence why I looked into recir BOV. I have a BNR32 that his mild tuned already. But 1 summer ago when my both BOV were working and at 17psi I had zero issue.

At the moment, I had 3 options:

1) Run one blitz and one OEM

2) Run the Turbosmart dual port alone

3) Run the turbosmart dual port and one oem

My friend's car actually run 2 HKS atmo and one OEM but I think the atmo take over the OEM bov. I will simply install it and run the car without bumper and see what can stop my stalling issue.

Hi guys might be a stupid question but what model gtr bov should you recommend or are they all the same?

I got defected with mine venting to atmo, I have an aftermarket plenum, stock bottom and aftermarket top half.

If my intake doesn't have a port to recirculate can I plumb it into my airbox? Or will that be not enough to pass defect clearance?
