power to weight - Toyota Yaris Forums

yeah, it is closer to 100 lbs per .1, but probably not quite that much. That calculator is better, but it still does not account for everything, such as how high the car sits for drag ratio and wind resistance. Or how tall and wide the tires are. Taller tires will spin slightly faster, while wider tires have more resistance, but get better grip at the beginning and in turns. That is why you pay the insane amounts of money for cars that are calculated and engineered to perfection, like Porsche, and Lambourghini (sp?), and Ferrari, and Lotus, and stuff like that. Still, taking dead weight out of a car is a great way to make it turn better.

well for sure power to weight calculation of dead-weight is dead on, but I'm guessing you're referencing the rotational weight reduction; I totally agree there is no single method to determine that, and I'm def. no engineer :D
