First off, I would LOVE to see that video...  Care to get in the video
rental business?  :-)  
Where did you get this video?  I'd really like to get my hands on a copy
of this.

Can you see the throttle assemblies?  I'd like to see the barrel
throttles that
are used on F1 engines.

>From what I understand, the injectors are mounted in that location to
try and 
improve the quality of the mixture.  An F1 engine turns 17,000 rpm and
consequently
has very little time for injection of fuel and atomization of same.  So
they mount the 
injectors above the intake velocity stack to give the fuel some extra
time and distance to
get mixed with the incoming air.
