Z31 Introduction
-
I have been thinking about this. I took a look at the rpm drop on each shift, and this is what i came up with:
gear 1-2....1700 rpm
gear 2-3....1100 rpm
gear 3-4....800 rpm
gear 4-5.... 500 rpm
This is a dyno sheet of the same setup in another z31. The only differance is im using e85 at 15 lbs of boost with 9:1 compression pistons and, he is using 93oct at 20 lbs of boost with 7.8:1 compression pistons.

judging by that dyno graph, and given that your car makes the same power at the same rpms, shifting at 6200 is about perfect IMO. Why go past that when your power drops off, when you can shift and be right back in the power again?

Those are kinda small don't you think?
Oh yeah it will still be slow!
