How much volume are you trying to push through there. We are up to almost 1gal/minute and getting fair smoke, but with the rotor downwash, it defuses The volumn of smoke oil you can pump through depends upon the volume of your exhaust gas. A bigger engine, or running at a higher RPM (or both) will usefully allow a higher smoke oil volume. For a big piston engine (eg 540 cubic inches) 1 gal/min should give very good smoke, with the right smoke oil. Check the flashpoint of your oil - betcha it's up around 400F. You'll get better smoke with a (CoC) flashpoint of 250F. As far as dealing with rotor downwash, you're on your own!
