T-Man 660 PS

This cam was designed for the customer looking for the max effort for their 103 or 107” build and is the go to cam in the T-Man 107 Thumper Kits and has been used in motor combinations as large as 124 cubic inch due to its high lift. Performance valve springs and adjustable pushrods are required. This cam produces excellent torque and power from 2000RPMs to 6500RPMs while maintaining its manners in town for rideability. We recommend roller-rocker arms when using with this cam. We suggest this cam be run at a minimum of 10.5 Compression and works very effectively at 10.8 – 11.0 compression while still maintaining the use of pump gas. Cold cranking pressure at 10.5:1 is 196 PSI and at 11.0:1 is 208 PSI at sea level.

NC State Sales Tax will be applied.

Description

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.
