Will a 1g bov sound the same as a 2g bov?

[PieEyedPiper]

I'm considering upgrading my bov to a 1g, and I'm curious as to what should I expect.
Will it sound the same? (i kinda like the stock 2g sound) and will it require adjusting?

Thanks

When I put one on my old car I didn't adjust anything. And I liked the sound better of the 1G BOV.

Ya they'll basically sound the same, except the 1g isn't a cheep plastic pos that leaks over 13 psi. Actually the 1g will probably be slightly louder since you will be able to hold more boost if you turn it up over 13. No there isn't anything to adjust on the 1G valve.

When I upgraded to a 1g it seemed louder and had more of a metalish sound if that makes any sense, It didn't leak so when it did blow it had more pressure going through it making it louder I guess. Either way it's 100x better than that stupid plastic one

Anyone else with 1G bov that knows if it is louder than 2G bov? I'm going to install one soon. Does the car perform better as well? Also what UIC pipe did you use? A picture of the setup would be kewl as well.

Yea I just put a 1G BOV on my 2G Talon. Its alittle bit louder, and I definitly like the way it sounds, how could u not!? Plus you need it if your going to be increasing your boost, after so much psi like 13 or 15 your stock 2G can't handle it, you need the 1G, so I would definitly go for it, and if u don't like it then youll know,but I would say test it out, but thats just coming from a girl.

the 1g BOV will hold more boost that a 2g. Do you get where I am going......1g

 

[zachakagoat]

Just go ahead and buy it, if you are wanting one that is just loud then I would go after market as they tend to be louder. But I would say buy the 1g, I bought one off the classifieds and then turned around and sold my 2g bov for the same price

1G BOV's are the bomb diggity.

$0-$50

Sound great.

Do the job perfectly.

Can be used as long as you want or need.

There will be a point in the order of modding that the 1G BOV will hold you back in some shape/fashion, But for under 600 hp its the best BOV on the market.

*yeah I have a 1G BOV....BTW it holds 24 psi just fine.

You guys that are concerned with the sound of your BOV will get a kick out of this.

We all know the BOV sounds different when plumbed to the intake pipe versus open. But did you know the type and even length of the return tube makes a difference? My UIC pipe has been through several incarnations on the path to the current state: 2.5 aluminum to GM MAF blow through. At times I had to be creative to get the thing connected back to the intake pipe. The results were interesting and in a couple instances, hilarious.

The Bugle. I made a pipe closely approximating the shape of the original return tube from copper fittings. The down side to a hard pipe is that it takes 4 hose clamps and some tubing couplers to connect. Slightly louder than the original rubber piece.

The Bagpipe. As the distance between the BOV and the intake changed again I needed something to temporarily bridge the gap. About the only thing I could come up with in my junk stash was a bike tire inner tube. Why not? I set off around the block to test my new setup. It was fine until I reached something near full boost and let off the throttle. Pow! Explosive decompression. The tube was split like something you see in a cartoon. Flower petal-like jagged edges.

The Pipe Organ. The bagpipe was replaced with a piece of convoluted sump pump tubing. I was curious if air rushing through the pipe would generate sound. Every kid must have seen or had some similar tubing that made musical notes as he whipped it though the air. Nothing. I eventually found that the original rubber tube could still bridge the gap if stretched slightly.

After recently installing all new intercooler pipe, my BOV was a considerable distance from the intake. No bit deal. Since I was now blowing through a GM MAF with translator with MAF-T, all I needed to do was protect the BOV from sucking in unfiltered air. More easily said than done and I decided it would be easier to snake a piece of tubing back to the intake. More sump tubing did the trick.

Now, when I let off the throttle with boost, the BOV blows off with a musical note and cycles down through 3 or 4 pitches before the pressure is completely depleted. Although very amusing initially, this one may get on my nerves after a while.

This makes me feel disturbed. My 1g sounds like a flutter when it blows off. *shrug* guess we'll see if it still does it with the new turbo.

 

[wret]

Crushed?

 

[swarm]

no, sir.

 

[wret]

Check the vacuum line. It sounds as if it is not opening properly. It definately should not "flutter."

 

[swarm]

Will do. Is there any way to test the BOV off the car?

Sorry for the hijack.

Just skip the crushing and jump to the testing.
