The factory used 3.154 for 1st gear in 2 N/A cars (both the Swiss 964 with the G50/04, and the 964 RS with the G50/10). So not all that tall...
Hence asking how folks got on with the 4-speed 1st - quite a bit taller at 2.6..

My friend had a 965. The 1st was so much more useful than my NA 87 Carrera 3.2 G50/01. The rollout made 1st so fun. Mine just hits the rev limiter in no time, then off to 2nd. I have too much torque to benefit from the low 1st gear - hence my belief the G50/50 is the PERFECT gearbox for most turbo 911's IMO.
The more torque you make, the less gearing you need. Small displacement 4 cylinder cars use 4:1+ 1st gears with 4:1+ rear diff ratios (at least back in the day).
Top fuel dragsters run direct to 36" tall tires.
All relative I suppose..
