SKU: 22210

The Racing Beat “Streetable” Exhaust Port Templates for all 12A rotary engines
allow you to undertake your own exhaust porting efforts.

Our Racing Beat laser-cut aluminum porting templates are patterned after our
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

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.
