One thing that you should keep in the back of your mind with regard to the Mazda Rotary application is that each barrel of the IDA was virtually continuously feeding three cylinders ( chambers if you like ) firing at equal intervals. Not the same as your 1 barrel per cyl application where the inlet valve is open for say around 280°/300° of crank rotation then closed for the other 420°/440°.
