I'll try to get Alfa's side of the story on our list in the next few
days, but let me quickly mention that event timing is not -critical- but
it has a very strong effect on the ability of these simple old motors to
deliver amazing throttle response. Especially off-idle, through midrange.
Injection event duration is timed and very short, with positive fuel
displacement at over 300 psi. The Spica [Alfa Romeo] system was used with
mechanical and electronic controls during the time of the 1000 hp
days in F1.
