how do you know whether or not your fifth and sixth ports are operating correctly?

I dont know if mine are. When I have the car in neutral and I go up into the engine bay and rev is, I dont see the actuator moving at all. I know im going above 3800 RPM but it is not moving at all. how do I know if they are stuck open or stuck closed? will they open in neutral?

 

If they are not opening, you're car will feel like its "bogging" per say @ higher RPM's (3800+). If they are stuck open, you will have a reverse effect, "bogging" at lower end. Massive lack of torque.

 

You should be able to move them with your hands.

 

even when the engine is off?


how exac tly do the mechanics of the whole system work is what I really want to know, if someone has a pic of what they look like open and another of what they looked like closed, id be a happy camper

 

here is a pic of them
you can put a lil bit of grease and take your car for a spin..if the shafts have no grease on them then they are working...if the grease has been disturbed from how it was when you originally put it then they are not working...

 

yea what do they look like? I'm curious? maybe mine aren't opening..

 

Do Turbo II's have 5th and 6th? i know its a newb question but i don't know

 

Yes Turbo II's have 5th and 6th ports.

 

No they don't.

 

Your cars ports are opened by exhaust backpressure. You don't have enough in neutral to open them. revving the engine and watching them won't do it.

One way to find out is to actually reach down and try to actuate them. You can do it by hand. Just make sure the engine is cold. The other option is to zip tie them open and go drive the car. If you are alot faster then you know they are not opening normally. If your speed is the same, they work fine.

 

ok i didn't think they did thanks rotary god

 

Whoops I was misled - sorry for misinformation heh

 

Ill try that grease trick... Im not able to actuate them by hand. I jsut dont know how to tell whether theyre stuck open or stuck closed

 

its fine adrock atleast you were trying to help me out.

 

sorry wasn't trying to steal the thread!

 

aux ports do not open unless there is a load on the engine.

you said:
Nope you are right, they won't move... not in neutral, not without a load on the engine.

 

by the way...when you do the grease trick go above 3.5k rpms...

 

I am pretty sure they are stuck. I ahvnt done the grease thign yet, but I cant move them by hand at all

 

there is a link to remove them and wire the sleeves open isnt there can someone find it? been searching today and cant find it.sorry not trying to steal thread.

 

why do you want to make your car even slower?

 

no worries since(hopefully soon) itll be turbo'ed

is cleanig them gonna be the same process as wireing them open, removing manifolds?

 

you should be able to hear the engine open up as you are driving along and it hits the rpm point
