T-Man 555-Torqster PS

This is the most popular cam for bolt-in applications on the market. No head work required. Lift designed for stock valve springs. Works well at 9.5 to 10.1 compression. A very effective combination with flat top pistons and stock or slightly modified heads. A noticeable increase in power and torque. Making it a perfect choice for two-up riding on curvy mountain roads where torque is desired while still providing the quick acceleration for hot rodding around town when one-up riding. This cam has a broad torque band that will start at 2000RPM and still pull through the higher RPM range. This cam has been used successfully in 96” to 110” builds. Cold cranking pressure at 9.5:1 is 182 PSI and at 10:1 is 194 PSI at sea level.

T-Man Performance has been working diligently with Andrews Products on our NEW Exclusive PS design to give our customers the quickest accelerating cams on the market while maintaining the reliability of longevity for valve train components and insuring the quiet running valve train requested by the Harley crowd. The new grinds are identified by the ‘PS’ stamp on the Cams.

At T-Man Performance, we take pride in helping our customers select the proper cam for their build. Your cam choice is critical for a successful build. We recommend that you contact us for professional advise concerning your selection.

Some of the things that can impact your current or future build are compression ratio, riding style and where you live. One of the most overlooked questions regarding a cam choice is – the elevation where you do most of your riding. A cam choice will vary due to altitude and compression ratios should be considered because of this variation.

Please be sure to consult a professional before making your choice.
