   Bill,
   Fantastic picture!
   Look back over the published data, then look at the Mazda intake at full
   blast, and you will come to the conclusion that for our purpose very
   short
   runners are best , the Mazda manifold lends itself to cutting and
   welding,
   whilst retaining the injector mouldings and fuel rail. What could be
   simpler? We just have to convince Tracy that 3 injectors are better than
   two.

   Easy, just tell me why.  You can run 3 if you want, no additional
   drivers needed.
