Chris,

If you want a spare 04/05 manifold to disect or cut in half... Let me know. I've got plenty of spares... I'll toss one out for scientific purposes... Lol.

I'm beyond broke right now. Saving for the wedding, and waiting on school loans. If I get my ducks in a row I'm hoping to get a new exhaust and a real CAI on the cougar, then bring it back to you for tuning. We could settle the whole debate on the Mondeo intake since I have everything but hood clearance taken care of.... If I close the hood you can feel a slight bump where the intake pushes up.

How much cam cover clearance have you now?

I meant for free... You'd have to pick it up ... But free

Cam cover there is lots of room, I cut off the tab on the back of the UIM that hit the cam covers the first time I test fit it. The COP units with the 04/05 valve covers is what caused my frustration, that and wanting to keep the EGR. From what I've read if I had dropped the COP units I could have gotten away with a smaller spacer, or if I had switched to the older cam covers things would have been easier.

Hmmm ... I'll talk to Tabitha about it, we'll be in Cleveland next weekend I think so maybe I can swing by.

so in this taper discussion, i come up with the question. "where" in the powerband does this taper (increase in velocity) take effectiveness? i have been reading a bit on airflow and such like mentioned before but i can't really get any good information on the advantages of tapered runners.

Again, if for large mass flow at high velocity, it is better to gradually build velocity from plenum to short turn. Slow it down slightly around the short turn radius and as Terry says 'give it a boost' into the chamber to keep the velocity high and unidirectional. You might check out info on venturi, laval nozzle, Weslake '3 zone' port, etc...
