I ran 3 different types of 240sx's.
Default, Shift at Redline, and Shift at power peak. Guess which one had the best accleration?
Time to 100ft
Redline 240sx (shifting at 6500rpm)

Default 240sx (shifting at optimum shift points)
3.3
Pre-Redline 240sx (shifting at 5500rpm)
3.4
Time to 500ft
Redline 240sx (shifting at 6500rpm)

1/4mile time
