Just wondering what everyone with FI Rx-8's are running. I am looking to put a ifferent one on.

I kinda like the louder ones IMO. Like the Turboxs RFL or the Greddt Type RS....

Any other ideas?

 

The Tial 50mm is known to be one of the best.

 

I have the HKS SSQV and the Synchronic.

 

I've had the greddy type-s, turboxs rfl, and the synchronic (used it with filter, anti stall fitting, and in recirculating mode combination).

I don't care for greddy's bov's. the turboxs had a nice sound to it, but people online complain about having to oil it. The synchronic is really nice, but if you use the AP, you can't vent it.

 

Only problem is you can't recirculate it.

I am very happy with my Greddt Type RS. Not too loud but not quiet either.

 

I had the Greddy Type S, then switched to the HKS SSQV & liked it better.

 

They make a recurc fitting for the TiAL. It's expensive though.

The TiAL and HKS SSV are the best, but I don't care for the SSV "shudder" sound. It's still a solid BOV, though. Unless you're running massive boost, BOV's realyl come down to sound and reliability.

 

Blow off valves must be recirculated when they are positioned behind the device which reads your airflow since your car has calculated that the air will be burned.

If your blow off valve is in front of your air sensor you can vent it till you turn blue in the face.

 

How is it that MM doesn't have to recirculate his BOV?

 

Mysql meant you can vent when you using AP and synchronic together

 

^I thought he was using those together

 

yea, he is and its recirculated, not venting to atmosphere

 

I could've sworn MM said he wasn't recirculating...i'll look it up

I have a greddy type s with the rs spring and I also have a turbonetics raptor. I like both but the type s is louder than the raptor. And also the raptor sounds like a snake hissing, very quiet unless I blow off in boost.

 

Jeff isn't. I am. I don't know why people keep thinking we're the same person.




If your BOV is working well, it's not going to make a prolonged sound. That's one of the reasons why the synchronic works so well, the sound goes whoosh and doesn't squeal a half hour like the type-s does.

 

mysql:
not to thread jack but why does Jeff's work uncirculated and yours didn't care for it much? (other then the fact that Jeff is the evil mad scientist who can pretty much get anything to work...)

 

MazdaManiac is using the HKS it stays closed while in vacuum. Mysql is using the Syncronic and it stays open while in vacuum. This is why Mysql must recirculate his BOV and MazdaManiac doesn't have to even though they are both using the AccessPORT.

 

I have a thread about the synchronic if you search for it. It works the reverse of how a bov usually operates. That's one of the reasons why it works so well, but unless your fuel management is map based, you have to recirculate it.

 

mysql...I didn't think you and Jeff were the same person, I got confused on what BOV you where using. I thought Ray told me both you and Jeff were using the HKS

 

i am kinda lost guys...plz some1 to clear me up...does the hks sequential 2 bov has to be recirculated???????

 

How about you point out the specific quote that made you think that, so we can explain it to you.
