Thanks for the info. The rice racing system seems interesting and I will look into it. I have not been into rotaries for years but am a former factory trained mazda/subaru tech. Back when I was playing with rotary cars, the only vendors were basically Racing Beat and the next runner up was Rotary Engineering (now defunct).
Interestingly, this is a jeep so it has an onboard air compressor already - also from Australia. It is a twin pump model designed for continuous use and filling up huge jeep tires. Maybe I can connect the systems together.
In searching around for air assist, I stumbled onto folks doing some sort of hydrogen injection with I think vacuum assisted nozzle. Interesting.
edit:
I have this aFe filter that has an inverted cone. I have enough real estate inside the cone to put a jet in the center aimed down the intake tract.
I don't know if this helps or hurts but the intake tract itself is 4" and I was thinking to bring it down to 3.5" or 3.25', which is closer to the stock size of 3.14".
Would leaving the larger size before the throttle body slow the charge and give it more time to atomize?
There is no room with my setup to really go port injection. I will take a closer look again later but I doubt port injection would work for me. I think I have to go 100% pre TB/SC/CC.
