OK, been doing a lot of thinking and a lot of looking, and I cant seem to find how the secondaries are controled. I mean, are they opened and shut by the computer, or are they mechanical, like a vacuum secondary on a carb? If they are comp controled, it could lead to all kinds of fun, like a "Secondaries Engaged" light on the dash (spoof "V-Tec" light, think it would be kinda cool) and a modification to the code, possibly forcing the secondaries to open under WOT sooner, etc. Anyone know? I dont want to rip the top off the motor for nothing.

You don't have secondaries. 1999 was the last year for them.

My mother has a 96 that I might be taking off her hands, she is looking into getting a Five-Hundred, so the question still stands.

EDIT
P.S. I dug up my 2004 sourcebooks. In it there is a section on Powertrains. For the 2003 3.0L DOHC 24V Duratec V-6 is the following quote:
"Variable induction intake with dual tuned runners for each cylinder optimizes low-speed torque and high-rpm horsepower"
Quote is from page 6 of the powertrain booklet. Comments?

I thought ALL duratecs had secondaries...

There are no secondaries on my '03.

Are you sure that is information for a Taurus? The same engine is use for Mazda, and Jaguar.

Dual tuned runners does not necessarily mean it has secondaries that open and close with butterflies. Ever hear of their "split port induction" motors?

Go ahead and pull the intake off if you don't believe me, but you're not going to find any IMRC system or butterflies in there.

And BTW they are computer controlled.

Nope, only Gen 3's.

Some people call the 2nd set of intake valves that open up in the duratec at 4,000 RPMs "Secondaries." Others call the second shorter path in the manifold (opens at 3,500 RPMs) in the 96-99 Duratec "Secondaries."

All valves open at every rpm on every Taurus built to date.

Exactly. Even though it has 4 valves per cylinder, it's not like only 2 of them open and close until higher rpms. All 4 of them work all the time.
