Top-to-bottom recipe for Pro Stock & Street domination!
160 Cubic Inch PROMOTOR

Pro Stock Racing ProMotors

The "Power Chefs" Randy Torgeson, Paul Matyka and Reggie Ronzello have pooled their talents to cook up this 160 cu in. ProMotor^TM for the new Harley^® ProStock drag racing class. Their inspired recipe blends Matyka's ProCasesª, side-by-side rods, Moon Rock Crank^TM and Reggie's radical R&R billet Proheads^TM with Randy's ProJugs^TM to satisfy power-hungry appetites.

R&R ProHeads^TM are the brainchild of Reggie Ronzello and Paul Matyka using Reggie's "cross sectional flow analysis" technology with all the right stuff, including narrow valve angles, vortex fins, and massive valve gear with precision CNC machined 6061T6 billet alloy.

Hyperformance ProJugs^TM are machined from Durabar^® ductile iron billet to create the toughest cylinders on the planet.

Street ProMotors

ProCases^TM and internals are testament to the genius of Paul Matyka. The crank pins are finished with a hex end that indexes into EDM cut hex recesses on the inside surface of the wheels so the inside area of the wheels is totally smooth, allowing sufficient space for the CNC billet steel rods to run side-by-side, while keeping the whole assembly very compact. Both sides of the crank ride in massive double tapered Timken bearings, creating a virtually indestructible bottom end to handle enormous horsepower at extreme RPMs.

ProMotors^TM for the Street. Hyperformance manufactures bolt on fin sections to turn the Pro racing heads into Pro heads for the street. THe first street ProMotor was built in a 190 cubic inch configuration for the Radical Cycle Predator (see RadicalCycle.com). The 2nd street ProMotor was built in a  205 cubic inch configuration for Doc Hopkins (see DocsHD.com) for the Woody. The 3rd is a massive 260 cubic inch Monster built for Radical Cycle Predator #2.
