Nice graphs. Swamp and TBone are using a simulation tool called CarTest, which pretty much does this kind of comparison for you automatically after you supply the torque curves and some other specs for the different cars.

On thing: as I mentioned in the thread where jm1234 posted his graphs, the RRI torque data are for steady-state tests. A real drivetrain under acceleration would produce less torque at the wheels due to rotational inertia effects and other dynamic variables. Also, different engines might respond slightly differently to the acceleration pulls.

DCT gearing in 3rd looks good!
