A while back, I was asking about the 1-2 shift, and got various replies. Looking back, I guess I didn't communicate myself very well, so would like to clarify things.
Most of you are probably familiar with this type of chart for the 427 Cobra:
You can see the shift at around 66 mph. I used this particular chart as it lists mph @ 6500 for each gear. So with a little interpolation, I assume the 1-2 shift is around 5570 rpm.
Here's another graph, similiar, but shows the shift a little closer to 70 mph, and is typical of others I've seen.
I don't shift like that. I usually get it somewhere in the 3000 rpm range in first, then shift to second so I am starting 2nd at the lower-end of the power band. I then run it up high in 2nd before the 2-3 shift. I do it by feel, not the tach (which has slow response, somtimes intermittent, plus my eyes are glued to the road during a hard accleration run, not the dash).
I can make the 1-2 shift higher, but it becomes less smooth and I don't think it's terribly healthy for the clutch, although I admit, the two are related to an extent.
So, my driving abilities aside, my tires aside, and knowing I only street drive, I have a question:
Who shifts close to 6000 rpm from 1st to 2nd, and who doesn't, and if you do, can you elaborate a bit on it?
Thank-you.
