What is the power of your new blower? In either hp or amps.
I am looking for a bigger blower for my large #30 furnace running a Lionel Brute. The 5 gallon shop vac I am using is not quite enough. I built a blower years ago from Gingery plans but it is not quite enough either.
It turns at 3450 now. Maybe if i up the speed another notch.

the data tag on the bounce house blower that I won off of ebay say's its a six amp motor.
you can speed up the gingery blower, but I'm not going to say how much as I don't know how it was put together and
fans when they come apart are not fun to be around. you could make one with wider blades which would give you more air,
Chastain has the numbers if you want I can scan those pages out of his furnace build book and post them for you.
I'm not going to say to change the way you burn oil, but you would probably get a lot better atomization of the oil which would give you a lot better burn by using a nozzle.
One problem I have with this new blower is that the burner port in my furnace was cast around a 2" pipe, which leaves me with a choke point in the air stream so I'm not getting all the air pressure that I should, basically even with the damper wide open, the amount of air out the end of the burner tube is only about half what the blower will actually push. so I have some thinking to do, even though it will probably melt iron. Thinking about a home made carbide hole saw to cut a bigger hole in the furnace wall for a 3 inch tube, I have some carbide inserts that I can silver solder onto a piece of 3.5" tube to make a hole saw with. But before I do that I've gotta get this damn back problem straightened out and see how much iron I can melt, I may leave it like it is.
