i think you rate the spec's time a little low too dude, i was pushing about a 15.1 before my MMI and light rims and short shifter, i havent been back since but im sure it will be sub 15, as for exact gear measurements..... i dont remember EXACTLY what mph/rpm i was at, id honestly rather be looking at something more important.....lets say, the road. im familiar with my car enough to know where its at in the powerband and i can associate that with a speed, forgive me if im a few numbers off, but i pulled that prelude pretty hard. take it as you will but i know all drivers are different, maybe get someone else in that dirvers seat and take me down?
