PORT TEMPLATE TOOL, J-BRIDGE INTAKE 4-PORT
PORT TEMPLATE TOOL, J-BRIDGE INTAKE 4-PORT
The Racing Beat Intake Port Templates allow you to undertake your own “J-bridge” port efforts on any 12A or 13B rotary engine (except 13B 6-port). 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 on thin sheets of aluminum 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 template is held in place and the porting shape is then traced onto each housing. You must then use your own judgment to develop the port shape beyond the scribed line.

Actual template shown in photo.
The Racing Beat “Race” Exhaust Port Templates for all 13B peripheral port exhaust rotary engines allow you to undertake your own exhaust porting efforts. The race version of these templates open the exhaust port further “upwards”, increasing the port timing duration which results in more intake-exhaust overlap and better high RPM performance.
The Racing Beat laser-cut aluminum porting templates are patterned after their own original master templates. Designed and refined over decades by Racing Beat’s legendary engine builder and co-founder Jim Mederer, this exhaust port template gives you a powerful resource to assist you in your engine upgrade project.
Incredibly easy to use, simply mark the template position as instructed, spray the exhaust port area with marking dye, hold the template in position (we use a simple hand clamp or a office paper clamp), and then scribe the new port shape onto the housing. It’s really that easy.
Porting Effort
During your porting effort we suggest you stay within the boundary of our template shape. This shape has been designed to yield excellent results for a broad range of engine building applications. However, you can certainly get more aggressive with porting efforts beyond the template line, you must then use your own judgment and expertise as a guide.SKU: 22216 -

PORT TEMPLATE TOOL, RX8 RENESIS, BIG HALF BRIDGE
Port Template Tool, RX8 Renesis — Big Half Bridge
This template is for “Bridge porting” the upper (secondary) and lower (primary) intake ports on the front and rear side housings of the 2004-2011 RX8 Renesis engines.
We still consider there is not enough port thickness, at the bridge area, to leave enough for a “safe” bridge strength at the center housing intake ports.

PORT TEMPLATE TOOL, STREET INTAKE 4-PORT
Port Template Tool, Intake Street Port (4-port)
Racing Beat Intake Port Templates allows 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 aluminum 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 judgment to develop the port shape within and beyond the scribed line.
