Re: (pie_ya)
Benefits:
- more torque on the road (quicker takeoff)
- quicker turbo spool (torque available earlier)
- shorter ratios (tighter powerband gearing)
Drawbacks:
- more torque on the road (wheelspin)
- quicker turbo spool (on/off behavior)
- shorter ratios (more shifting)
- reduced top speed
- reduced fuel economy
- need for other adjustments
It would completely change the car, that's for sure. Whether for the better, that's unclear. This is why I suggested prototyping it with smaller tires first.
I was considering the reverse, taller gearing, primarily for the fuel economy. The V50 T5 FWD gets significantly better fuel economy than the AWD, and it isn't (all) the additional weight and rotating mass. Just a thought experiment for now however.
