5th & 6th Ports (For a S4)
I have a question. Does anyone know (by experience) that this will activate the auxilery ports better then the exhaust backpressue method?
Also, should I be able to move the plunger on the actuator with my fingers? Because i can only get it to move about 1mm.

Not sure on the actuation, but the plungers should be able to move freely throughout their entire throw with fairly light finger pressure. Also, if they're off, you should be able to blow into them and actuate them.

yes, they will open around 3.6K-3.8k RPM using that set up.
I currently have my vert running that way.
And yes the actuators should be able to be moved by your fingers

That'll work, but it depends on what the relief valve part of the ACV is doing. In other words, if your ACV is still working with all it's inputs (switching valve, split air solenoid, relief valve), you're not gonna have air at that hose all the time.
A much more effective way is to route the air hose to the air pump-to-ACV hose- full-time air, & greater pressures...In fact, you'll have to install some form of "relief" valve into your actuator "feed" hose to keep the ports from opening at less than 3,000 rpm. I use a simple plastic "T" for this, with a "calibrated" hole drilled in it. With this setup you can actually get the aux port valves to work when you want while sitting in the driveway, since back pressure produced under load is no longer needed. In other words, you can experiment with different rpm opening pressures by varying the size of your "relief" valve.

What cat? Lol...
I've actually tried both methods (or hoses) to open the ports, and get much better results using the air pump outlet for pressures. It's always "bang" on at 3800, whereas the ACV exhaust supply was a bit more temperamental...Hey, whatever works for ya, man...

Now the S5 (which uses a different set of actuators) they are designed to be slammed open, but the S4 motors do not see any benifits from that.

wait i have a question about this set up. my ports arent opening up sufficiently because i have gutted the pre cats and have a new exhaust set up, and this set up looks interesting but how do they open up the ports? Where does this piping lead to? What does it do?
thnx

I don't understand your other questions though... they have been covered in the top part of this thread.
So again, the tap'd pipe is the exhaust/dump pipe from the ACV and it vents to under the pass headlight area.

o0oh. thanks..i thought air would come in from the other end..hahah sorry guys. i did the set up but when i had it revved to 3.5 rpm the ports arent openin up. it wouldnt open up till like 6 or sometimes not at all. does it require load to open them up?
