Power to weight on its own doesn't tell a whole lot either, because although weight is weight, power is not power. We are just talking about peak HP. No one is talking about torque. Or how that power is delivered. If I have a peak power output at 7000 RPM's versus one that is there from 4000-7000 at the same rate, of course the second car will be faster. Look at the power band of a Comptech supercharger versus a centrifugal one like the basch. The Basch has a higher power output, but it's a narrow band at a peak. A CTSC has less, but it is much more broad. Power CURVE means a lot and it's not talked about at all everytime a power to weight ratio conversation comes up. A car with a superior power curve can be geared completely differently, and it will walk away from the car with the inferior curve everytime. Even though they have the same exact power to weight ratio. This is even more of a determining factor than aerodynamics. And we are just talking acceleration. Heavy is not good once you need to turn and brake.
