if you GUYS are still confused at why 5252 is significant,
power (hp) = torque (lb*ft) X RPM/5252
torque (lb*ft) power (hp) X 5252/RPM
if you look at a constant torque curve and a constant power curve, both will intersect at 5252 RPM in which power (hp) will always exceed torque, concluding that higher engine speeds (such as at 9k rpm) take advantage of greater volumetric efficiencies
also, if geared correctly, it will allow the driver to stay in a single gear while cornering as opposed to having the shift while steering
