This is my Honda odyssey 250 HP V6.
It appears to have several  HR's.
One large one for each bank and auxiliary
smaller ones to tune the torque curve through out
the rev range. It works very well.

There is probably is a lot of R&D associated with this design.

Here are some diagrams out of the shop manual.
If we can get this to work on the RX8 engine it will
be a much more compact tuned intake and will fit
under the typical cowl.  We might get as much
as 220 HP at 7500 RPM if we are lucky and one
has a 3.12:1 gear box.

Those of you with cut off stock RX8 six port manuals
let me know the dimensions of the plate you welded
on. So far Scott and Bob.

My best guess is 4 by 4 by 13 inches long with
as 3 inch diameter intake pipe and throttle body..

If the plate is wider than 4 inches something like
3 by 5 by 13 inches might work.

4.5 by 3.5 might also work.

 A Maximite can measure the pressure as a function
of RPM for fine tuning. A 3/8" thick plywood box will
work and can be cheaply changed if the volume
needs adjusting based on the Maximite data collection.
