[s-cars] RS2 EM alternative on Ebay

[Dave Forgie]

All I was trying to say was "equal length" header runners is meaningless
phrase in itself.  If the equal lengths were equal shape and discharged
to atmosphere like a 60's Swamp Rat IV dragster, sure that would
probably be important.  However, when the "equal lengths" are all
twisted and turned differently, what is more important is the flow that
will pass through each runner at the same head loss.  The exhaust flows
and the head loss (back pressure) should probably be the same if each
cylinder is to put out the same number hp and torque as its four brethen
(sistern?).  Otherwise, some of the piglets are going to be more equal
than the other (so to mix a metaphor).

Of course, this is based on Civil Engineering non-compressible flow
background.  However, I think it still is valid (for the most part).

It was just and observation about the design of that header/EM on the
German eBay.

No wars intended or wanted.

I stayed out of the WGFV "debate".  I still don't understand why there
was a debate.  There is only one right answer - the one the Audi/Bosch
engineers designed.
