Does anyone have any pic's were they drilled there factory upper plenum for a extra vacuum line.Or were to drill ? I need a line to my map sensor and I already have to many coming from my factor fitting. Any help would be great have a appointment to get it tuned Wed.

 

Instead of tapping your plenum you might want to think about a throttle spacer. I did and it works great. http://z1auto.com/prodmore.asp?model...ne&prodid=2414

 

I would drill and tap for each line you run into your manifold, don't use T fittings and hook multiple lines to a single bung.

 

throttle spacer looks like a good choice, give you 3 extra lines, plug those that arent needed. Its a little costlier than buying a tap, but if you dont have a drill and drill bits, I think the throttle spacer would be the best option.

 

why are you asking the same question twice in the same section?

 

did not mean to double post!

 

Powerlab makes a really cool vacuum distribution block. I would have one of those, but I already had the AAM throttle body spacer w/ 3 ports.

 

Thanks for the pic I thought under the brake booster would be good just wanted to double check. I have a appointment wed for a tune and need to get it done asap. Went turbo sold procharger

 

here's my setup.

drilled and tapped the upper plenum and am running a dedicated -6AN line into a vacuum manifold.

 

Is that like an external manifold to provide multiple ports to tap off of?

 

I did the same exact thing on my car (tapped location and manifold location) and it works great. I made my vacuum manifold out of some extruded -10 fuel rail though from Ross Maching Racing.

 

That's funny. My first vacuum manifold, I made from Fuel Rail stock, too.
I was running a manual boost controller at the time, and this manifold was for feeding the side ports of my wastegates. (I am running -4AN preassembled nitrous lines as my vacuum lines to the wastegates.)

 

we usually just tap the upper plenum on the back side of it. clean and effective.

 

drilled a hole last night under the brake booster line thanks for all the help.

 

I like Andrew`s setup alot !! its so clean and mean, i`ve ordered this Vacuum Manifold its so damn small !!

it got two 1/4 NPT ports and five 1/8 NPT ports and its only for 29 bucks.

 

Nice....
