If I were to get the vacuum block would it neaten up the installation in the engine bay as well?

I don't think so. The brake booster line coming out the back of the manifold is visible. The tap Sasha makes in the IM is hidden under the engine cover.

Of course you could make everything tucked away with enough effort and zip ties.

I think I'm going to go with aam intake. Vacum source taken care of...

Edit: Has 4 auxiliary vacum ports flows better and looks bad ***......

The reason I suggest the IM be tapped at the front is to have the vacuum source (IM) as close to the BOV as possible. This increases response time and opens the BOV quicker between shifts, which is what you want to see. The BOV manufacturer also recommends the BOV have it's own designated vacuum source.

Do you think the extra inches of vacuum hose may cause an issue? I, too will have the manifold tapped twice to provide a source for the boost gauge. Thought it would've easier with the vacuum block.

I don't believe you need to tap the IM twice with the SCG-1

The gauge pressure should be able to come from charge pipe. It don't need to see vacuum..... I believe this is correct...anyone?

The boost gauge needs to see vacuum. Take it off the IM.

Can you explain to as why "boost" gauge needs to see vacuum. I really have no need to see how much vacuum my engine is creating. All I care about is positive pressure. Just politely asking.

Chuck33079 · 02-21-2016, 10:15 AM

Why would you do it any different than the rest of the world? Otherwise the gauge would just sit at zero. I guess you could do that? But tapping the im and doing it the normal way is easy.

Plus, with all the new piping, vacuum leaks are a real possibility. How would you know if your boost gauge was only plumbed in to see positive pressure?

TcRocket · 02-21-2016, 10:28 AM

I guess I really have no desire to see how much vacum I'm making. And if I were to have a vacum leak it would barely Bo noticeable however upon boost it'd leak like a bitch. So I really don't see the reference there. I'm only trying to keep a healthy engine based upon boost pressure not vacum. The boost controller controlling the waste gates will only see positive pressure so why should the gauge controlling the solenoid need to ever see negative pressure. I'd rather see a gauge at zero instead of jumping all over in the negatives. If I don't see a number above approximately 3k then I know I have a line leak issue. Just my .02

Do it however you want, but there's a reason everyone else who installs a boost gauge does it that way. And doing it the right way takes no additional effort since tapping the Im takes minutes.

TcRocket · 02-21-2016, 10:43 AM

Just the way I seen Sasha state was that only the bov needed to ever see negative pressure. I've yet to install my turbo so I'm always open to advice.....

. Just saying how I was looking at it wrong or not and if I am I want to know the right....

What's the reason?

Side note..........anyone going to Z days this year. Never been plan on going

You have to drill/Tapp the manifold for the BOV. It only needs vacuum.

My reason for utilizing a vacuum block. Tapping the intake manifold or a vacuum block, they both serving the same purpose. Per Sasha advice, it's best for the BOV to have its own vacuum source with the shortest path. Very good advice. Doesn't make it wrong to do. No way between the two is wrong. I got this idea from VipViper who utilized the vacuum block for his build.

The aem intake with the auxiliary vacuum ports is super sexy I do believe and functional....
