What did you plug your MAF pipe with? I'm scared that whatever I put in there is going to get sucked in the turbo.

 

And you should be
Back in the day when I was blind I used the "hks 2g kit" and it come with a plug
It popped out more than once

 

Dont do it!! I did, and went back to the logical route. the way the car was designed.

 

all the more reason not to vta on your setup.

 

Most of the VTA BOVs come with a plug. But you could probably build your own out of a short piece of PVC pipe and a cap for a couple bucks.

But I'm sure you know that the logical option is to vent back into the intake if you have a MAF.

 

I used my OEM bov and plugged it in backwards...

 

wow thats amazing! you blew a plug off the MAF pipe? how did you do that?do you have a pre intake turbo or something? you realize that the MAF sees pressures at or below atmospheric, therefor a plug on the MAF pipe (however unlikely) would actually be sucked into the turbo, not blown out....

 

The plug is not very deep , so the worm clamp dosnt relly get a good bite on it .
No it was not sucked into the maf pipe it does have a lip on the plug .
Maf pipe is at or below atmospheric pressure , I would have never guessed it ....

 

For those that are still using Maf, I would not use a Bov that only vents to the atmosphere. We have put many vta bov on cars with maf and it doesnt perform the way the car should. The maf will go a little crazy and at times will just dump fuel. There has also been known drivability issues. People running map with an ems can use a vta bov, because you get rid of the Maf.
Now there are different bov that vent as well as recirculate and those have worked out fine. Most people should look into purchasing one of those.

are you running ems or other maf elimination? if not then dont do it, it will cause a overly rich condition every time you let off the gas.

 

beat me to it chris

 

It will do this regardless, only for a split second though so the computer can catch up with the signal output from the MAP sensor. I know that the 05's around me don't have a problem running VTA while still using the MAF sensor.

 

I just switched from VTA to recicurlate setup for the HKS SSQV BOV. I can feel the difference after I did it. The car runs smoother and pull a little harder than before. Probably pressure was leaking somewhere and I fixed it when I switched back to recic. setup.

In addition, I can run about 20-25 more miles consistenly per tank after I did that setup.

Before I was in the VTA setup, the cap that came with the SSQV BOV poped out also. I had to go to Home Depot to get another plastic cap. That one fits perfectly and it did not get poped out. As someone mentioned, the cap that came with the BOV was not deep enough for the clamp to clamp it down.

Good luck for the VTA setup, but I would defitnitely suggest you to go with the factory setup (recic.) for various reasons.

 

I've been hesitant to post this since there are so many threads on the topic and I've done plenty of searches, and it seems like a sore subject with a lot of people. I bought my car used last week ('04), it came with a HKS SSQV BoV that is VTA. It runs fine, idles fine, though I have noticed a tiny bit of flutter when doing small throttle adjustments in 4th gear.

I keep going back and forth on what to do and all my searches seem to have confused matters for me moreso than help my decision. At first I thought I'd get a recirculation kit, then I read of some people still having problems after that and saying it was a waste of money. Then I thought I'd get a Forge DV or an MR DV and read of people having problems with flutter on those as well. So now I'm kind of at that point where I don't want to touch it since I'm not having most of the problems that other people are. As you can see I'm a little lost, I'm really not the type to do mods to a car that won't benefit it simply for a sound, but I'm also thinking if it ain't broke don't fix it.

Even if I'm not noticing any driveability issues am I doing damage and is it likely my car is running rich due to the VTA? I know this has been answered before but it seems that the answers are all over the board so I'm just trying to get a more definitive answer.

Thanks,
Ike

P.S. Bd how easy is the recirculation kit install?

 

I have an 05 with a GFB hybrid BOV. Since it is adjustable I had plenty of opportunity to test the effects of VTA vs. recirc. You could say the car runs "fine" with partial VTA - it depends on your tolerance level. For me, even with the BOV set to the smallest amount of VTA, there's too much surging at partial throttle release & high rpm. As a drag racer you may not care, if you road race and balance your car at the tire limit through turns using LFB & throttle you do care ...

So playing around town I set it to partial VTA (yes I like the sound, I'm not too cool to admit it), but for any type of serious driving I set it to full recirc. Adjustable is the best way to go IMO.
