can you replace the bypass valve on the G trim with a BOV?
can you replace the bypass valve on the G trim with a BOV? Just wondering since the G trim doesn't start producing boost until after 3000 rpms if you removed the bypass valve and replaced it with a BOV like on the T trim would it cause boost to start building sooner and in the long run cause you to have more boost up top?
I asked this question on LS1.com and got no responses. It may be a stupid question but can I at least get a response saying it is, if not is this a possibility. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: can you replace the bypass valve on the G trim with a BOV? Don't think it's a stupid question.
I don't know the answer, and some folk don't venture a guess because when they try, suddenly you have people who pounce on the post and ridicules them... or claim it's just an attempt to inflate their post count. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />
Either no one is sure, or the right person hasn't seen it yet. Keep that "ttt" handy. <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Re: can you replace the bypass valve on the G trim with a BOV? This may not REALLY help you, but check out Hugger Orange SS's BOv he put on his procharger:
<img src="http://community.webshots.com/storage/1/v0/0/17/91/40101791TeLPqU_ph.jpg" alt=" - " />
He has a nice write-up about the BOV and it's affect on the ATI SC system here:
http://www.ls1.com/forums/showthread...eferrerid=9599
Maybe an issue or two from his discussion will give you some ideas to chew on.

Re: can you replace the bypass valve on the G trim with a BOV? Chad:
I have the same setup as you but with the 13# pulley. I do not have a boost guage hooked up all the time. I guage it whenever I dyno and I was seeing 12# at wot (7100 rpm) and put down 576 rwhp. Last time I dynoed though I only saw 10# and 510 rwhp. I think my belt is sliping. Where are you tapping in at?
Black LS1 TA:
Thanks alot there is some great info in that thread. I have already experianced the raised heads and oil shooting out of the dipstick after I uped to the 13# pulley. I tore my engine down and found the rings damaged and replaced them and studded my heads thinking that was the problem but maybe not according to this thread (although the rings were an obvious problem). I am a little confused though H.O. SS talks like the Vortech already has a BOV and it just needs to be upgraded. I thought the V-9 came with a bypass valve and that is why it does not start produceing boost until after 2900-3000 rpms and just free spins at idle and lower rpm. Maybe it has both I guess I will call Vortech and see if they will give me any info.
Thanks again guys for posting and the info.

Re: can you replace the bypass valve on the G trim with a BOV? If this is anything like the vortech on my mustang, then no. If the bypass valve is located BEFORE the mass air meter, you can replace it (you aren't blowing measured air out). If it is NOT, you can't.
If the bypass valve is located after the mass air meter, the car will run very rich when the blowoff valve opens, as the car thinks more air is entering the motor than actual.

Verdad Gallardo Re: can you replace the bypass valve on the G trim with a BOV? well I went ahead and ordered the BOV from that thread he said he alredy put it on his friends with the vortech so I am going to try it
Andrew:
The setup is like yours with the bypass after the MAF but this guy alredy tried it and said it worked also it should be open only after the throttle body is closed and should not affect the metered air. I guess I will find out thanks for the reply.

Re: can you replace the bypass valve on the G trim with a BOV? I'm interested also in how ur progress comes out. I first hooked my gauge into the vacuum line that is coming out of the back of the aftercooler and that was showing no boost at all <img border="0" title="" alt="[Eek!]" src="gr_eek2.gif" /> . Someone said that it sounded like it was behind a check valve. I now am hooked into the line on the back of the intake before the check valve and it still almost always shows vacuum until I get the rpms way up there. It may be possible that my belt is slipping. <img border="0" title="" alt="[Confused]" src="images/icons/confused.gif" /> I love my set up and definitely that whine but I would love to get all of the bugs worked out. <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" />

Re: can you replace the bypass valve on the G trim with a BOV? I believe that Vortech puts the MAF on the inlet side of the supercharger according to the photo on the website.
