Blitz SS/DD BOV

Post by **captain nismo** » Fri Apr 04, 2003 6:19 pm

Does anyone out there have the Blitz Super Sound / Dual Drive blow off valve? I was wondering how loud it is? Does the loudness depend on the motor much (like s13 redtop, blacktop, etc...) I want a fairly loud BOV and the Blitz one looks nice.ThanksChris

It is supposed to be fairly loud and the loudness would also vary, not so much based on the engine but on the turbo and how much boost you run. Here are some reviews and sound clips for you. http://www.alltrac.net/tuning/blowoffvalve.html It lists the blitz as "extremely loud" Hope this helps

Doogz,

sweet post man.

Thanks for the help and the intresting post Doogz.

It's loud once the boost is raised. I though mine was pretty quiet until I went to .9 bar. It may be a bit loud but it puts out a killer noise and that is nice.

No problem guys. I'm glad you enjoyed it

Sorry sort of off topic but does blitz make an adapter to fit on the bov to recirculate?

Post by **Ace** » Fri Apr 04, 2003 6:19 pm

No adapter to my knowledge. But I have seen a few people that just make a little metal piece and then connect a little hose to the intake tube. It seems relatively easy.

Is it better to recirculate the let off, or is it better just to vent it to the atmosphere. I don't want to lose the cool whoosh sound you know...

and what are the problems associated with NOT recirculating the BOV. I know that the ECU will trip up because there is air passing thru the MAF that is going unaccounted for. but what is the result?

the DD is quiet. if you want louder get the older Blitz Super Sound (tonnes on ebay) or Turbo XS RFL!

I have heard that the car will die sometimes when you come to a stop. But I haven't had any problems with letting it go into the atmosphere. Yet anyway. Knock on wood.

The problem with not recirculating is that the car uses a MAFs, which has already accounted for the air that is being released by the BOV, so sometimes the car will stumble following shifting when under a heavy load.

I'm going to have my BOV mounted on the hotpipe since i bought a hotpipe with a flage from heavy throttle. When having a recirculating valve does it matter on the location of the BOV? Like i've seen most recirculating setup with the BOV on the cold pipe. Would it make a difference if I recirculate it from the hot pipe?

Post by **Ace** » Fri Apr 04, 2003 6:19 pm

No I don't think it makes a difference.

Post by **float_6969** » Fri Apr 04, 2003 6:19 pm

would it fix the stumble problem if you moved the MAFS to the pressure side (ie-right infront of the throttle body) or at least made it a blow through?

Post by **Ace** » Fri Apr 04, 2003 6:19 pm

No you should definately not do that.

The Super Sound are known to not perform as well and have problems. the Dual Drive comes with a stainless mesh element to mute the sound if you want to be a bit more stealth. BTW- why buy a HT hotpipe AND the unuversal BOV when blitz makes a complete hotpipe replacement included with their SR Dual Drive kit? Don't worry, they are plenty loud without the stainless element!

the way you fix the surge problem is to get a fuel computer and lean out the fuel , my cousin had the same problem with his mr2 turbo

Ace -- What is wrong with running blow through?

If you dont wanna do that, just deal with it till you can get a full computer with a MAP sensor =)

Post by **Ace** » Fri Apr 04, 2003 6:19 pm

Well I have never heard of doing that. It may work but it will really hamper the flow of the air to the throttle body. Those stock MAFS units are small. Anyway maybe you can. But I wouldn't do it. Anyone else got any opinions on this?

Post by **float_6969** » Fri Apr 04, 2003 6:19 pm

I've never actually done it either, but a guy on here with a KA-T did it with his swap and he had a FM with an atmospheric BOV and it worked just fine for him. I don't like MAFS all together. I don't care where you put it, it's a restriction. Granted that it is probabally better to have it on the suction side of the turbo than the pressure side, as far as air flow is concerned, but if you want to fix you stumble for the price lengthening the wires, it's a pretty cheap way to do it and I don't really see you restrictin the air flow THAT much. Your computer would also be getting a much more accurate count of the air going into the motor as it would be adjusting for the dense cool air as apposed to the hot engine bay air. Maybe someone with experience can elighten us.....

Also what you could do is get the HKS unit ( I forgot what its called) It completely eliminates the MAFS.

D'OH! I never really understood how they worked. Too bad they're gone now, wonder why they discontinued them. From what I remember, they were pretty expensive. Nevertheless, I was kind of interested in them. Shucky

I'm sure you can still find them. Check Ebay and other places.
