Porting Templates

These templates have the port shape scribed on an aluminum plate for each port listed. The actual port size and shape needs to be cut in the aluminum to the scribed lines. The Turbo and 6-Port templates are pre-cut on a CNC water jet. Templates allow easy marking of the housing (dykem or permanent marker, then scribe port) and consistent port opening size/shape.

We now offer intake porting blanks for those engine builders who have their own special port designs. A very critical part of porting is to make ALL the ports exactly the same. With a porting blank, you can make your first port, then transfer that design to the template, then use the template to scribe the rest of the ports.

We have a reasonably detailed explanation of porting (and use of these templates) in our FAQ Section

We also have a DVD which details the porting process start to finish. Click Here

Renesis Street Port Template

49-22203

The Racing Beat Street-Port Templates allow you to undertake your own intake and exhaust porting efforts on all model years of the high-power 6-Port Renesis 13B engine. These porting 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 housing. The finished template is held in place with the tubular dowels and the porting shape is then traced onto each housing. Included with the Renesis porting templates are Racing Beat's exclusive detailed instructions and advice to guide you through your porting efforts. Limited clearance on the 6-Port Renesis side housings creates additional challenges when porting these housings, our instructions provide detailed photos of the most critical areas of concern.
