Default Boost/Vacuum source for multiple feeds.

So I've been reading and it looks like most people source off of the brake booster for source of boost/vacuum. I'll need to have three references for boost. One for the gauge, one for the BOV and one for the Hobbs switch(dual pumps). The wastegate I plan on running a line right from the turbo to the port on the wastegate. I'm running a standard ls6 intake.


I have one of those blox vacuum manifolds and my plan was to get a simple T from autozone and T that off of the brake booster and run it to the manifold.


From the manifold I'd have my BOV, hobbs switch and boost gauge connected.

Does this seem logical or am I missing something? Thanks for the input guys.

That's how I did mine. I had mine drilled and tapped for 1/2 inch 1/8 NPT barb fittings. But this is the one I went with

Well here is a dumb question. Since I'm doing the !AIR mod anyway could I just use that connection on the back of the ls6 intake below the MAP sensor?

Where is a good place to buy these blocks? If anyone else has pictures on how they did this I would like to see them. Great pics Sweet SS, thanks.

I need to at least tie into boost pressure for my boost gauge and hobbs switch, how would you guys suggest I do it?

I have a block mounted where my battery used to mount, and a 3/8" rubber line to the ls6 manifold behind the TB on the passenger side. Think that was originally going to the valve covers, dont need that with boosted applications anymore, works great.
