The dyno run shows a comparison between the R and RS models.
The RS is targeted for the track and the R for the street. Mechanically the engines are the same with identical cams, intakes, and exhausts. Differences in their respective power curves are purely due to tuning.
The R actually has higher max torque overall and more horsepower up to 11,000 rpm at which point the RS pulls even and then gains horsepower until the 12,600 redline where it tops out with about 2.32 horsepower more than the R.
The RS comes with other goodies that are track oriented (suspension, brakes, tires, and a quick shifter), worth the $1,100 difference if you plan on track days. Otherwise, the R seems the better choice for street use.
