For best acceleration, you want to shift at a point where you will fall back into the peak torque of the engine. I have my shift light set at 6200RPM, by the time I see it and shift I'm near (but not on) redline. After the shift I'm right back in the meat of the torque band (above 4k RPM) and still pulling hard.lupohki said:I'm a newb at stick. Can someone tell me the at which revs for the STi I should be shifting in each gear for the best acceleration? "Lowly" passenger cars are out in front of me from a stop, unless I mash on the pedal, which I don't feel I should need too.
ya the reason it felt faster (now that I realize what is going on) is because It jumped to 17.5 PSI in 3rd... i didnt realize i was getting boost creep in 3rd until today.bitabur said:It might feel that way, but if you're trying for MAX acceleration, you're best bet is to keep it floored the whole time, and drop the clutch after shifting.
I have a spreadsheet on that if you want it. Back in the summer, I ran some calculations, as did someone else on nasioc. Basically the shift points are roughly:jim said:Back in June when I first got the car, someone posted a plot of the effective torque curve for each gear on one chart.
I've just searched all over for it, and I just can't find it. It was basically just a plot of the torque at the wheels for each gear. You could tell the proper shift points by just looking at where the plots overlapped. Based on that chart, it was best to stay in first until redline, and then until 6k or so for the rest of the gears.
