Both Proto and Plus4 have awesome bottom end...... our track has so much bite and is so technical that it requires the engine to have piles of slow speed grunt..........Its very easy to bog a engine out on this surface, so everything is tuned to have more grunt.....very difficult to run a low stall clutch here.........
