Bill,
It's been over a year since I studied the Renesis intake but this is
what I remember.
The lowest rotary valve in the Renesis intake shuts off the secondarie
intakes at low rpm. It is full open for high rpms. The next rotary
valve connects the combined primary and secondary intakes from
rotor #1 to the primary and secondary's of rotor #2 at high rpms.
With the engine running at high rpm and with both valves open the DIE
can work. The DIE path length is from one rotor intake valve (at the
rotor face) up to and thru the second or upper rotating valve (in the
open position) and back down the other intake tube to the other rotor
valve face.
Hope this makes sence!

Yes George,
I was referring to the Renesis
manifold. Specifically though, I was talking about the valve that
produces the
D.I.E. effect.
What a
terrible acronym.

I'm
hearing you, I guess you mean
the Renesis manifold. Maybe someone can duplicate that in carbon fiber,
in a
more compact form. I know - another job for Bill Jepson.
George,
It’s a shame
that the stock intake
that does all this using a valve, can’t be used in our application.

I
missed where the 43" came
from, however from my calculations for 44mm inlet tube, my calculations
came to
21.36". That's for a straight tube inlet manifold. That's interesting
isn't it.
This is hard
for me to visualize as well.
Perhaps if you get a chance, you could snap a picture from the top.
Did you get
43 in. from #1 secondary to #2
secondary?

Dennis,
I just looked at your picture
again…the
secondary look much longer than the primaries. It may be an optical
illusion??? I bet you mean 1 1/8 id??

All my tubes are the same
length and the same diameters. I can check but I think they were 1 1/4
id. and 1 1/4 od.

Dennis,
Aren’t your primary and
secondary tubes
different lengths from rotor face to rotor face? If so, what are
the two lengths? Are they different diameters?
