In any case, Indian’s trying to repeat that scenario now, saying the new PowerPlus will outperform the bigger Thunder Stroke 116 engine (although the 116 claims a similar torque peak of 126 pound-feet). To hit those lofty performance goals, the new ’Plus borrows a few design tricks from the acclaimed 1,133cc Scout engine, primarily the overhead camshaft design that uses four valves per cylinder. It also includes hydraulic valve lash adjusters and hydraulic camshaft chain tensioners for ease of maintenance and reliability, and like the Scout’s, cylinders are splayed at 60 degrees. But make no mistake, the PowerPlus was developed with an overarching big-piston, big-torque theme to squeeze out maximum power delivery across the entire curve. If the 122 hp peak at 5,500 rpm holds true, it'll eclipse the 100-hp Scout or the 120-hp (claimed) FTR models, and doing so at much lower revs to boot.
