First post here, hello everybody.

I'm looking for some feedback on Renesis header design, which may be
mostly theory at this point due to the newness of the design. With the
Renesis having zero overlap intake/exhaust timing, gentler exhaust
port
opening/closing timing, and a shared siamese center port between the
two
rotors that is smaller than the end ports I'm wondering if the
traditional header concepts for scavenging, tuning, etc. are now out
the
window.

Thoughts?

Yes it is an interesting situation. In theroy the center pipe
should be around 16 inches and the two outer pipes 32 inches.
The center pipe pulses twice as often and the pulses are
180 degrees apart e-shaft rather than 360 degrees on the end ports.

Something like this might work.

Paul,
Rotate the loops towards the center, one on top, and the other on the
bottom to reduce the height of the assembly.
