nothing, I personally just wanted to be able to control when they open from inside the car for experimentation, i figured it would be simplest converting the system to electric solenoids and a variable rpm switch.



Oh and I have an S4 intake that uses backpressure, which I have very little of with full RB exhaust, and no air pump... so the aux ports stopped working.

hmm see i have an rb exhaust and my ports work fine

You know, I was looking through my 1st gen manual and found instructions on testing the 5th and 6th port actuaters with low compressed air, like 2.5 psi or something. I always hear of people using tape or grease to check if they move or not, so I just thought using the compressed air would be easier.

yah, that would work, and then you could put a boost gauge in the 6 port line

well mine did til i replaced the stock y pipe and stock mufflers with the rb ones, then my top end disappeared... wired em open and it came back... the motors may have been a bit tired or sticky.

i cleaned mine out, and they stay clean cause they open and close all the time

we are getting off the subject here . :smirk: . I think that you would need MIL spec solenoids to take the hell-like underhood heat out cars create. that is a very expensive way to do this...and you can get little continuous air pumps for a fair price

Now thats a a nice NOS setup in that pic.
