need help figuring out shift points

[mrQQ]

sheesh, and that's supposed to be correct info? it's not.

you shift so that your drop of rpm puts you in max torque AT WHEELS on next gear. and since in most of low end cars torque AT WHEELS on next gear is always lower than torque at wheels on current gear at redline you switch at it - and NOT before it. and HP has got nothing to do with it.

hehe, I'm sure there's been a torque vs hp argument here....probably half a dozen or so. I always find them entertaining, but I don't want to waste a lot of typing if there's several copies of the same stuff somewhere around here.....but I'll give my standard summary.

Torque is a static measurement. HP is a dynamic measurement. HP is torque applied over distance and time. Torque by itself involves no movement, no distance. its static.

Since we're interested in getting down the 1/4 mile (distance) as fast as possible (time) then we are only interested in HP. And incase its not obvious, this is why you don't see a whole lot of diesel rigs drag racing. They have buttloads of torque, but very little hp for their weight. That is why they are slow in comparison to a track dedicated gas car.
