I would like to get some input about this BOV especially on a supercharged car. My plan is to install one of these on a 5th gen. in the near future. Any input would be much appreciated and I would like to thank everyone in advance.

I have it on my turbo setup and it sounds great. I get kinda like a flutter sound at low boost and high pitch release on higher boost. I like it more than the others like a RFL or Greddy.

 

I think the sequential is the best sounding bov, imho

 

I just posted this in the "Pic of reclocked blower and 3 inch piping" thread....

Well, after checking the SSQV out, it does seem to cause some compressor surge. It does not vent any air at idle, where the stock Bosch BOV lets out TONS of air at idle, and the sound "flutters" when I shift at low rpm's. At high rpms, it chirps like I'm used to. I now have this growling sound too, which I think is the air turbulence in the charge pipe. However, I'm not absolutely positive, as I built and installed a CAI (using a K&N air filter capable of 900 cfm) and that could be the source of the "growl" or at least contributing to it. I might temporarily use Ptatoheds BOV pipe/Bosch BOV and see how it affects the "growl" sound.

 

I have one on my set up. What do you want to know?

 

Do you have the compressor surge problems I described above?

 

sure do, I know its not great for the blower....it sounds hardcore though

 

damn right it sound hardcore.

what does a compressor surge do tohugh? if thats a way noob Q then dont answer

 

Forces the air to reverse and go back out throught the blower. Very bad for it.

 

Yup. I'm selling my SSQV. It may sound cool, but I'm not going to fu<k up my blower over it. Function>sound IMO.

 

you will get compressor surge with any BOV at low rpm's. Its not as bad on a Vortech as it would be on a turbo application. You aren't going to mess up your blower with it, you think its bad with an S-trim you should have heard how bad it was with the T-trim I had.

 

First off, your avatar is hilarious, lmaoooooooooooooooo


Second of all, so the final verdict, yes you get compressor surge from the ssqv, but its not bad at all for the vortech. CAN SOMEONE CALL VORTECH AND ASK THEM THIS PLEASE? I'm at work, i cant....thanks

 

Compressor surge on a vortech blower is not a negative thing for the blower. On a turbo application its really bad. I have had compressor surge with the Greddy BOV and the current Vortech BOV tightened down quite a bit. With the Vortech loosened a bit I get NO compressor surge at all...it vents a BOAT load of air though.

Ive heard that the SSQV is the best to get because there are two valves in there and one opens for low RPMs and one for HIGH rpms. But after reading this I think its BS.

This is 100% factual information? You called Vortech Matty? I'm happy if it doesn't screw up the blower. Some people say yes, some people are saying no, some people are saying "a little bit". Do we have to take a vote or go right to the source?

Yeah, tell me about it...A bunch of . But it sounds like it does have separate valves, one chirps at high rpms, the other flutters at low rpms.

 

You are too paranoid over something that is minor and unavoidable with a BOV. Vortech is not going to tell you Compressor surge is ok for the blower but I would take the word of myself and every other SC'ed Maxima with an aftermarket BOV. You will get surge at low rpm shifts bc its not enough air built up for the BOV to fully release and you dont want a bunch of air venting at idle. Most have run these setups for 20k+ miles without problems so I doubt any would arise out of the blue.

 

Thanks for the information. Pardon me, but I am always TOO paranoid with the car I love. SSQV it is for me

 

After talking to Steve the other night, he told me that HKS SSVQ will not work on the 5th gen. because of its dual valve design. Him and I didn't get a chance to finish our conversation, but I would like to make sure that I should be looking for some other BOV beside the Bosch bypass valve & HKS SSQV to install in the near future. Thank you very much in advance.

Andrei

 

The dual valve design has little to do with it. If you keep the MAF before the Blower and do not have emanage to do a anti-stall then you need to vent the BOV released air back into the non-charged pipe. So you would need to buy the recirculating fitting to do this on a SSQV.

 

SPiG, I told him the exact same thing, but I didn't know that they had a recirc fitting for this. Sorry I didn't have more time to talk Andrei.

Yeah, but it won't make the sound that he wants.

Andrei, they already have flanges welded on. Why not use those?

 

Steve, no problem what so ever. I'll try to find a better time to give you a call next time. I am a little bit concerned about the sound that the BOV will produce, although don't forget that I have a V1 which is going on the car. So I am not to sure at this point how much of a BOV effect I will hear over the SC. Also the pipes that I have has do not have the flanges for the Bosch bypass valve. The flange on the intake pipe had been welded off, and on the charged pipe there is a Greddy flange which is welded on. Although converting the flanges back to original condition so that the Bosch bypass valve fits shouldn't be any problems what so ever. So I would like to ask for everyone opinion on which BOV or bypass valve to go with.


Thank you so much for you input as well, I appreciate all of your help. The reason I am so concerned about the BOV, is because I've heard some negative things about the Bosch.
