Information Specifications Reviews

Racing Beat Intake Port Templates allow you to undertake your own "street" intake porting effort on most 12A or 13B rotary engines (except 13B 6-port and Renesis). Rotary tuners long ago discovered that changes to the intake port shape will alter intake timing, allowing increased airflow and velocity improvements. These templates are traced from Racing Beat's own master templates, which are the result of years of research and development. The actual port shapes are traced onto thin sheets of aluminium which you must first cut out, testing your ability to use a die grinder effectively before attempting to port an expensive engine component.

The finished Racing Beat porting template is held in place and the porting shape is then traced onto each housing. You must then use your own judgement to develop the port shape within and beyond the scribed line.
