You need to find out what your vacuum is at idle, with the engine fully warmed up. From there you need to get the correct BOV spring. I am guessing your vacuum will be in the -18 to-19 Hg. Which means you need a lighter spring. Til Sport also recommends that each BOV has its own dedicated vacuum source from the manifold, via 1/4" hose, with no more than 48" between BOV and vacuum source (manifold). This is why in my instructions it tells the installer to drill the very front of the manifold, to keep that hose as short as possible.

BOV's work on vacuum, and if the vacuum in the manifold is not strong enough to overcome the spring, you could see compressor surge because the air has no way out, if the BOV is not opening fully.

With this out of the way, you at least know this part of the install was done correctly.

hey gonna pm you. thanks for the response.

Does anyone have the link to the new version of the kit? I have the V1 instructions. Thanks

SOOOO>>>.<<<< here I am guys, going to need some help since i haven't done this before. I have one bov that is on the driver's side. I have two waste gates on the passengers side by the turbo. Unfortunately they ran the whole set up wrong so my brother and I have to redo it. They feed the BOV off a t that was coming of a vacuum on the back of the manifold; the other line was going to the boost controller. It also looks like they ran the waste gates off of separate t's. I will have to get the G reddy instruction and make sure to do it right. ..... They seem to have a t that they don't need. What I am gong to do is just rerun it. I do have a few questions if I can ask.

What my bother and I did today, was correct the bov by tapping the manifold and running a dedicated line for it. I have gotten to change out the spring yet so I still don't see vacuum. And on to the waste gates....I cant seem to get them to work. I have both ports on the waste-gates hooked up one line down with a t to the WG on the bottom side, and one line with a t coming back up. This is were I get confused. I have a greddy profec, which has a control box with a inline filter. a solonid with port 1 and 3 being used with port two with no plug and left open. I ran the control box line to the nipple on the charge pipe and put the lower WG line to port 3 and the upper WG line to port one. I did it wrong and I know just looking to get it right really need some help.... Thanks guys!

Edit

i'm gonna look dumb but I don't understand the picture... I under stand the BOV part but the part on the left and the right are the ones I don't understand.
what is the second vacuum line coming off the front of the Intake manifold? I also don't see were the solonid is? did you hook up to port one and come out port 2 while leaving port three open or block? sorry for the question's i have never run a BC before...

I fixed it!!! The part i didn't get was the control unit and the waste gates are seperate systems. I had to tap the fuel pressure regulate, and not try to plumb it in with the waste gate system. Now i just need that re-tune from aam and will be good to go, but I was seeing my vacuum, boost, and not over boosting like it was. So very good day. I want to thank those that help me figer it out. Also just for the record because of the way it was hooked up AAM is compensating me with a AAM intake manifold.

Sorry for ******* up your install, here's a $2k manifold!

Glad you got fixed before your car pooped. That would be no good. A new manifold is a decent compensation I guess. It's not like you didn't pay them big $$ then they took it then messed up doing an install of what they specialize in. But like I said, a decent compensation due to the fact that your car didn't boom (could easily have with overboosting).

Glad to see AAM with an effort to make it right. Hopefully no permanent damage done during the overboosting and a $2k manifold is a pretty sweet freebie for your trouble. MAKE SURE THE MANIFOLD CASTING IS CLEAR AND CLEAN!!!!

I think it is fair, I never wanted to overboost but it looks like the tech hooked it up for a twin instead of a single. Then since i have never hooked up a bov or waste gates i had to learn; which was about 8 hours and a few drinks in lol. I still have to check the vaccum at idle and set the spring. Does anyone have a idea about waste gate springs? I have the seven pound and using the pressure for the BC, should I keep it this way or go to a heavier spring? Still learning....

I suggest keeping the one you have now as long as its working the way you want.

Are you using a boost controller? Then here's what you need to know in selecting a spring:

In the general case, you want to select the lightest spring that still allows your boost controller to hold the target boost all the way to redline.

If you have too light of a spring, the exhaust pressure at high rev/load will be able to push the wastegate flapper open on its own.

Too heavy of a spring, and you won't be able to dial the boost down if you need.

Now, you may want to go a little heavier that "the lightest you can" so that you have room to raise the boost later down the road... There is probably a range of springs that will work now and in the future.. And don't forget, you can always tension the spring down for adjustment.

You guys are confusing BOV springs and wastegate springs. Glad you got it all figured out. Let me know what your vacuum is at idle and I'll get you the correct BOV sent.

Ok will do sasa it wont be worked on till Friday so anout a week. Were is the best place to get the vaccum measurements from? I was going to buy one of tbose five dollar ones from ebay. Or would it be better from autozone?

Anywhere on the intake manifold. A cheap gauge will do just fine.
