Streetable Exhaust Porting Service

Streetable Exhaust Porting by Racing Beat (All Rotary Engine Models) - This service provided by Racing Beat requires the use of "new" housings, supplied by either the customer or by Racing Beat.

Streetable Intake and Exhaust Porting involves changing the size, shape, position, and surface finish of the ports and port runners. The power increase from porting varies, depending on the other modifications made to the engine, but averages 20 percent. Low-RPM torque is reduced slightly, but idle is still smooth. Intake porting includes two primary and two secondary ports. Exhaust porting includes both exhaust ports, and is performed on new rotor housings only. The labor charge shown is for two (2) housings.

These services are performed at Racing Beat's production facility in Anaheim, California. Prices listed are for labor charges only. Return shipment freight charges are not included in the listed price. Contact Racing Beat at (714) 779-8677 (M-F, 8-5 PST) for further technical information, scheduling, turn-around times and shipping information.


* Legal in California only for racing vehicles, which may never be used upon a highway.
