Copy that!!

Here's an experiment you can try.  Put all 4 on, but connect the pairs 
to separate throttle cables.  The problem that Ed cited with his early 
system was to much cross section at the low RPM to get enough power to 
reach the high RPM.  Mazda did essentially the same trick with the 
6-port.  A valve closed off one of the ports until sufficient RPM was 
reached to make use of the extra cross-section.  You can tell all your 
peeps at the airport that the extra cable is your special rotary 
overdrive that you've been developing in conjunction with the military.
