George,
I believe they experimented with several different
configurations including one with all the injectors at the far end.
However, as best I recall they felt they were having detonation problems caused
by the "higher" octane components "distilling" from the mixture and leaving
"lower" octane components in vapor (combustible) form whereas the higher octane
components were reverting to liquid form in the intake - or something along
those lines.

Bill/ Ed,
I thought they had two close primary and 2
out near the TB Secondaries?

Ok, thanks, Bill
My person experience has also indicated injectors
closer to the port turn out to give me a smoother and better running
engine. I have had all 4 out as far as 21 inches and found throttle
response and starts in cold weather not to my liking.

I find it interesting that after all of their
experimenting with injector positions - they chose to have all four very
close to the intake port.

Ed, Francois claims this is the best position for
efficiency and power in their tests. That jibes with the comments that
Mazda made for the RX-8 injectors in or near the port.
