Naturally Aspirated

The peripheral port is positioned at 90 Degrees ATDC opening time and 165 Degrees ATDC closing time.

It is recommended that a new rotor housing is used for Peripheral Porting. Used housings will be measured and inspected before machining to ensure they are satisfactory to our strict standards.

All housings will need hand finishing to suit individual porting preferences. There is enough material in the sleeve for approximately 10 Degrees of opening and closing duration available for individual porting requirements. 

For information on Peripheral Port Kits see the Peripheral Port section of our products page.
