Let's put your theory to the test. We are going
autocrossing on the 12th of November. I'll lose 50 lbs
and you gain 50 lbs. With a net of 100 lbs difference
we should have a .74 pound per horsepower difference
which comes to .4 seconds at the autocross.

BTW- My bike has 3 pounds per horsepower. I have no
doubt that a roadster could beat it at an autocross
though.
