A Periphery ported side exhaust is better than both i= ntake and exhaust being periphery ported. Neither the intake or exhaust por= t ever closes. So, there is exhaust dilution of the intake flow based on th= e amount of exhaust back pressure. Up to the point where RPMs do not allow = enough time for this to occur.Then it sort of steps up on the cam and the p= ower comes on as if by an electric switch. The full periphery engine tunes = like a dirt bike.  The intake length and diameter and the exhaust leng= th and diameter tune like a trombone. 
A periphery ported 12-A can do 310 HP at 10,000 RPM. = A 13-B can do 330 HP at 10,000 RPM. We have to be under 105Db at 50 feet at= full throttle. The Renesis has zero overlap. But it had a Micky Mouse inta= ke with 2 different tuned lengths.
