| JUST RELEASED! |  | | JIMS 131" Race Engine | JIMS is proud to announce the new 131" Twin Cam Race Engine. The 131" features the same stroke as the JIMS 120" at 4-1/2", but carries a larger bore diameter of 4-5/16". JIMS R&D Team has added many new features to further enhance the performance of this engine. First, to feed air to the 131", CNC Ported Heads were developed for effortless airflow. Next, they upgraded the oil pump to the high-flow design found in all current production Harley-Davidson® Twin Cam Engines. Of course these enhancements were made to increase performance, but they also decreased engine temperatures. Throw in a brand new JIMS Billet Cam Support Plate, which utilizes Harley-Davidson's new hydraulic cam chain tensioners, and finish it off with the latest in high-performance tappets, JIMS Powerglide™ II. As always, power delivery is as smooth off the bottom as stock, with a wide powerband of roll-on punch. These enhancements, plus 130 HP* and 135ft-lb* of torque, take the 131" to an unmatched level of performance and reliability in race engines.
*Horsepower and Torque performance measured at the rear wheel with a Dynojet© Dynamometer. Your results may vary based on E.F.I. Induction (non-carburated), camshaft and exhaust combination. This is not a street legal engine. | |
