has anyone tried a blow off valve on the ralliart yet? if so what did you go with?

 

Some ppl have the the evo9 BPV on, BOV's are bad though

 

How are BOV's bad?

 

You need a recirc BOV. All g63s come with it. You can get a forge, greddy type S or RS

Check this Vid out for Comparison

---Edit---

And i know its a ralliart. Doesn't change the fact that its not suppose to be recirc.

 

Metered air is released thus the AF ratio is thrown off. Seriously, if you want the "psssh" sound, get an intake.

 

So i just need a recirculating BOV then?

 

I'd say read up on this if you haven't really had any experience with a blow-off-valve/diverter valve.

Are you increasing boost? If not you would be best served to keep the stock valve and if you are increasing boost the one from the EVO X would be most likely an upgrade. In my experience aftermarket BOV's never work as good as the old 1G DSM recirc valve (which happens to be the valve of choice for the Nissan GTR). Making noise at the expense or compressor surge just isn't good modding.

 

I've heard the Evo IX bypass valve works.

 

it should. And they are more then enough for the RA turbo. Just make sure it is a IX or the VIII MR BOV. because they are not plastic!

Also if you want to hear the whoooosh sound , your best bet is the open element filter.

 

I drove a ralliart this weekend and the BOV looks just like the stocker that came on my 8, I bet a 9 JDM DV would work very well on your car. There are plenty around, just see if you can find someone to lend you theirs so you can try it out.

 

Ohhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh.................. ....

 

Its great to learn! Cause Knowledge is POWER! lol i love family guy.

 

Hell yea. Did u see the jack @$$ episode?

 

the EVO IX BPV works great, I have had it on for about 3 weeks no problems and you can hear the wooossshhhh check my video out, you can heard it on the 2nd and fouth rev. of the engine, but since you dont have to let your foot off the gas when you shift you dont hear the BPV when you shift. When I get up or pass 3K rpm and let of the gas I can hear the wooossssshhhhh that you all are talking about
