Every once in a great while, I'd feel something 'kick in' at about 3500rpm. After doing a search and reading, I hooked up a digital gauge reading psi, 'teed' a line going to the rear actuator and a small pump. It took the pump 3-5 seconds to reach 3 psi, then both acutators would engage all the way. Then, I took it for a drive will the same hook up, the pump and gauge in the passenger seat. At about 3-4k, I'd turn on the pump. Pump ran, gauge read about 3 psi, I noticed nothing new from the engine.
Is it possible the actuators are working, but not affecting the sleeves? Do the sleeves turn, or go in and out?

Could be. If its like a Mark V FC, the acuator rods have a small spring in the middle,, so its possible for the linkage to turn without opening up the sleeves. If you suspect this, removing the intake manifold is a sure way to find out.

They could be working and yes they do turn/rotate... and they are to operate under load.. when they supposedly opened, did you also floor the accelerator??..it does no good to let in addtional air without the fuel.

I didn't floor it, but let me ask this. If I move the actuators during idle, should the idle be affected? It too, does nothing. Is that telling me that the sleeves aren't moving, even if the actuators are?

If the actuators move then the sleeves will rotate..the actuators depress, turning a rod which rotates the sleeves. Yes the rods do have a very thick tensile spring inside of them and coated with a hard plastic making it just about solid..makes me wonder why theyre even made that way...Idle will not be affected, which is why those who have them tied open have little or no change.
Shortly put, if the actuators can be depressed by hand without binding or they turn when your car is running and when the throttle is gunned from 4000 rpm up and you see them depress freely all the way they are working.
SE owners::: want to 'feel' the 6 port 'kick'? well sorta...get underneath your car and follow the split air pipe thats connected to the main cat or RB presilencer whichever you have...right before the check valve theres a vacuum hose that is attached there and it runs into the back of the lower intake manifold, maybe Brownmound can show you the pics of it.. this sends the 2-3 PSI backpressure to the actuators.. disconnect this hose! Drive the car around..punching it to redline, it will feel flat on power, especially in the lower gears..1st and 2nd. After feeling the approximate 20% loss of power.. simply reattach this hose and drive it around again, youll go now this is normal I have the Pineapple Racing sleeves and those smoothen out the airflow so well Im unaware of any true power gains... The only way to 'feel' any 6-port kick is to drive the car steadily at around 5000+ RPM then mash the pedal to 7000. An S5 FC will have more kick due to its dual intake design along with the 6-ports.

I pretty much did this..I ran the car with the hose off (connected to my pump, pump off) gunned it, slowed it, etc. then, I did the same thing with the actuators 'actuated, felt no difference whatsoever in any power band. I'm confused..is it working or not? I have a 2nd gen guru (Kevin @ Rotary Ressurection)that is planning on taking these out and putting pineapples in..I'll be really disapppointed if there's no difference.

The whole idea behind the FI 6-port setup is to have a more seamless powerband without much of a noticeable "kick". That is, the throttle response feels more "linear". There definitely is NOT the "kick" of the 4-barrel's secondaries opening. Just the way it is. -WG

There has been times I have felt, especially when the engine is not fully warm, a small 'kick' at about 3-4k rpm. It didn't do it all the time. Others on the forum said it was normal, thats the 5th and 6th ports. This rarely happens, though.
Guess the best thing to do is have the guy do the work, at least I'll know then its working.

I dont feel anything at all in my vert and I know they are working...

MIKE-P, if you move your actuators during idle, does the idle change at all?
