Re: Ford injectors



I wouldn't suppose , that GM Multitec "disk " type injector doesn't have a uniform spray pattern. Recent , Bosch , Lucas and Seimens also offer Disk style , which according to design criteria are less susceptible to varnishing and have improved "fuel inertia" characteristics. OEs' are twiddling with the spray angle , atomization and shape of cone , aim @ Valve / Bowl. The voltage span on Ford /Denso injector is "slightly narrower range than GM spec , still within GM acceptable range. Likely, FOMOCO inj. / drv. has a different debounce scheme , so Inj rattle on open/close, when used on GM. Just some food for thought. No damage to PCM or Injectors? , car runs strong ?, noise is easily fixed , turn up the tunes. BTW good '94 ^ Lt1 Multitecs work great on warmed 5L Windsors. Delco Rochester needs to get price competitive.

Me too.  That was a supposition, not an assumption.  :-)  I'd love to see
spray pattern comparison data, the GMs are cheap and plentiful as the guys
driving '94-'97 LT1s love swapping them out.

These are the Multec design if I understand correctly.  I got two sets,
will snap a pic of the base and post to the list.  Very unique design,
they pass the fuel thru a machined plate with holes in it.
