I was just looking at your signature..... Well you need atleast twice the number of pistons then rotars to just get a car going. So do the maths and work out what is better. .. and did calculations....
Well... we need four/six times the pistons to move the bloody car but half the pocket to feed it.....
another thing..... that one rotar's life is 100,000 km/h (max) and the four banger's five times of that....
now you do the calculation!
