Did a search.

Is there anyway around using an ACV but still retaining function of the 6 ports? I'm already using a RPM switch for the VDI since I'm using the 87 chassis.

I could have sworn there was some way around this using the air pump or something...but I think the ACV ties into the air pump.

 

aww c'mon your making me feel like a newbie

 

The AVC can be removed but the air pump must stay. The aux port and VDI actuators take their feeds from the air pump before the AVC. Study the 89 FSM, it's all in there.

 

Sweet,

Now all I have to do is find someone thats rigged up a rpm switch to the 6ports a la 89+ system. I know it's been done on the S4...

 

Um, you've already got one. It's called the ECU...

 

'87 chassis...

Just rip all that crap off and rig up a linkage and a solenoid to pop the sleeves open, and control it from that RPM switch That'll be my plan, anyway...

 

Yes 87 CHASSIS, wiring all 87


If I just get a new ACV will the 6 ports open okay with the 87 stuff?

And if I get a header, will the 6 ports still open?
since the 89+ system does NOT use backpressure, right?

 

 

I have a pacesetter header and a hollow main cat (still have factory mufflers) my 5th and 6th open fine..

 

Should be, unless he's using the 87 ECU with the 89 motor.

 

Yeah, but I mean if I get a header with the 89+ motor will it still be okay, is there a way to open the ports without the ACV on the 89+ engine

 

 

 

Anyone?? pleeeeeeeeeez
