And do we know the overall gear ratios for the 997TT-TipS and manual?



Yes, the final drive ratio (what RC called the overall gear ratio) is 3.06 for the 997 Turbo Tip and 3.44 for the 997 Turbo 6-speed. By multiplying the final gear ratio by the specific gear ratio you calculate the overall gear ratio. For the 6-speed in 1st gear it's 3.44 x 3.82 = 13.14 overall.

The turning force at the wheels is flywheel torque x the overall gear ratio (assuming a rolling radius of 1 and disregarding transmission losses).
