Gear Skipping

Shan2nu · 25th May 2010, 19:59

Most road cars use wide gear ratios, so it doesn't make sense skipping gears while upshifting, unless you've achieved a good enough speed in the lower gear.

On my OHC, i always make sure the gear im shifting into gets the engine speed to a min of 2000rpm on a flat surface. If it's an incline i increase this rpm to 2500-2700.

Someone driving a turbo diesel could get away with doing 2000rpm even on an incline. So how/where you shift will change with the transmission and engine characteristics of your car.

Just curious here, but shouldn't the fallback RPM lie within the power band (especially for turbocharged diesels) ? The 2nd and 3rd gears on my baby Innova are wide apart in terms of ratios and hence shifting up at 2850 ~ 2900 revs leaves me at 1100 revs at the 3rd gear.

The powerband apparently starts at 1400 revs and if I'd want it to fallback here, I'd have to shift up from 2nd at over 2200 revs. Does that make any sense?
