Pat: mid range is not low range, as you see from dynosheet, those gains come from 3-6K and increase noticeably area under curve. Just noted typo of (U)EL
. I also second that it's more beneficial to concentrate on mid range vs targeting only short range near redline, where engine is at only for small fraction of time prior upshift from all used rpm range pre-post gearshift. For me on most tracks i've been to, used range was even from as low as 4K (to redline obviously. Stock gearbox, stock FD). Maybe sometimes there might have been extra torque/power in lower gear, but i see no reason to loose two seconds on extra downshift-upshift back to gain better acceleration for one second. I guess, only cars with variator gearboxes can benefit from absolute top numbers instead of higher increase at most of used range, as variators can use engine at constant most power rpms with always matching best gearing.
