Hi,
I agree, this is great to get the real world scoop on injection.
Ford; like on my '99 4.6? I can see throttle body injection as continuous just
like a carb, but when the injectors are right in the ports 'spitting on the
valves' are they flowing steady and wouldn't that defeat the advantages?
Of course sequential makes more sense. Is there a mid-ground with systems that
might have say 4 'channels' running an 8 with the appropriate cylinders paired?
Good answers always give birth to more questions. ;-)
Cheers,
Rick
