 Rotary Engine Porting
Mild - aka (Mild Extended, Small Street Port)
Mild and extended ports are very similar in specification, but a mild port is a slight increase in porting over stock. An extended port is usually slightly more powerful and a tad louder.
A mild port is the first step to rotary porting. This version has been "shaped" slightly with a metal porting tool towards the upper area of the port, increasing air-flow and top-end power without creating any significant drawbacks.
The adva ntage is anywhere up to 10% more power can be reached, with the torque range extending higher up the rev scale, you can expect around 200 hp for a Mild Port  with good induction & exhaust. Popular port due to there low emissions, noticeable increase in power, regular idle and drivability without changing the standard engine’s characteristics. These are preferred ports for a car that's 100% street driven, due to their value for money and blend of drivability and power.
PRO'S: Smooth driving, good for daily street use
CON'S: Slight fuel consumption increase
