Ok guys, got a question because I'm working out some math for an IDEA!!!! (AS IN DON'T START FLAMING ME FOR HAVING A F****** IDEA. EVERYTHING STARTS AS AN IDEA WITH SOME MATH AND LOGIC BEHIND IT!) Ok, now that that's out of the way.......

I'm wondering how long the intake runners are on the 2000 Vulcan alloy intake manifolds. And, does that length include the lower manifold or just the upper or is it the entire distance from the valve to (_blank_)? Is that blank the TB, the top of the upper intake, or what? Of course on the 2000 the runners are all the same length as opposed to the Gen 3 manifold that cylinders 1 and 4 curve over. Here's a pic of the manifold I'm talking about....(thanks Mark/TaurusSEtypeS)

Or where can I find it or who do I talk to? I've already checked my Ford CD's engine specs, but it wasn't there obviously. I'm hoping you know Bob, or know where I can find out. Or if anyone else knows, thanks a million.

I don't know what the length is, but if you are trying to work out the resonance, you would want to know the distance from the plenum (the large tube behind the TB where each individual runner starts) to the valve.

yes. I am trying to derive a formula for the resonance given RPM and (possibly) air density as well. But would that be to plenum wall that the runner connects to, or the wall opposite the runner opening?

From the plenum wall where the runner connects. You want the actual length of the runner.

***edit:***

The sound waves bouncing off the other side of the plenum is just one of the many factors that add the "reality component" (read: screws up your science) to the theory that you are working on.

its for a vulcan ranger, but the math will translate over to the taurus. Good luck!

WOW!!!! Thank you SilvaPain. Unbelievably awesome. Totally makes's my idea worthwhile and possible. This is why math kicks a**.
