Streetable Intake Porting Service

Streetable Intake Porting by Racing Beat (All rotaries except 6-Port Intake) - This service provided by Racing Beat modifies the front, intermediate and rear housings as supplied by either the customer or by Racing Beat. (Price includes labor for all three housings.)

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.

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.
