if you look at the dyno charts of the engine and calculate the torque to the wheels after it goes through each gear and the final drive then you can see optimum shift points. redline in 2nd gear puts down more torque than 5k in 3rd or whatever it lands at when you shift. it takes a car with a really weak top end or really strong mid range or a combo of both to make redline shifting not the fastest. your gear ratios multiply torque to the ground....get a dyno chart, your gear ratio's, your final drive and the points where the rpms land when you shift and do some math. the redline works best on pretty much any honda
