it is if you are comparing 2 different cars with 2 different setups, with 2 different drivers. there are too many factors. tyres, suspension, tyre pressure, clutch, rpm launched at, compression of the motor, etc.
here's an example. 2 cars run at the drags. 1 runs a 10.46 @ 131.3mph with a 60ft of 1.66
another car runs a 11.36 @ 119.3mph with a 60ft time of 1.648.
does this mean that the second car is more powerful because it got a better 60ft time? no it just means it got a better launch.
