Quest for MPH !! (caution, ricer math inside) !!!
From my exp. MPH for me is a Weight to HP Ratio and yes there will be other mitigating factors such as air quality, track conditions, suspension, gearing among other things that you can do to tweak that result. In the end getting the weight down, and getting the motor to the RPM that works best.
IF MPH only matters then ditch the auto and go manual you pick up just from that alone, especially if you go for a LIGHT weight flywheel.
I am of the mindset that ET matters more then MPH so some of this throws the idea of a good ET out the window but there are definitly options to think about.
