What is the best position for the smoke injectors in the exhaust.
Should I point them so they spray 90 degrees to the exhaust stream
or keep them spraying parallel to the exhaust stream?

Have a P60 in a Baby Boomer with Sullivan pump.

Right now I have injectors laying up against the exhaust nozzle. Then
they come out past the nozzle to form a V that almost touches together
about 2 inches past the end of the nozzle. The Super-Dri generates great
smoke but I noticed a lot of residue on the driveway and also on the bottom
side of the elevator. Doesn't seem like its atomizing all of the Super-Dri.
Thought the exhaust nozzle touching the injectors would help preheat the
oil enough to totally atomize it.

At Florida jets I remember seeing a large P200 with the injector passing right
through a hole int the exhaust nozzle. Thus spraying right inside the exhaust nozzle.
Would this be the optimal setup??

if you're not vaporizing all the fluid you can pinch the end of the injector to a fanned out shape that spreads the spray pattern of the oil, the smaller the droplets the better chance of vaporization. FWIW you shouldn't need to be preheating the oil, the jet blast is of sufficient temp to do the job if you inject the oil at the optimal position, with you saying your tubes are coming together in the jet blast you're injecting to far into the stream, you should be about 1/2" inside the blast and adjust that relevant to necessity. if they are to far in you'll burn the oil and get a flame, to far out and you get residue, with your setup you're to far inside the jet blast and the nozzles are to close to one another and they are joining oil streams and forming larger droplets which are harder to completely vaporize before they cool off, that is your residue.
