I wonder, what is the practical limit of torque/power that can be put down on the Roadster with semislick tyres like R888?
It has been discussed several times on here that 160-180 bhp is the limit for a Seven type car beyond where there are diminishing returns from extra power. Perhaps that is the limit of typical road tyres with the roadster's weight?

Put the same driveline in a car weighing 45 tones. Will the gearbox survive less well than in a car at .45 tones.
The torque required to accelerate the heavier load is much higher.
