Jeez dude. Your math is waaaaay wrong.
For chassis weight it's way more than that and probably somewhere in the ballpark of 8-10lbs per horsepower.
Using your math if I shed 100 pounds my car would pick up the equivalent of 214hp which is not true.
For rotating mass its a 1:4 ratio. 1lb of rotating mass removed is equivalent to 4lbs of chassis weight removed. 10lbs off of wheels/tires total would be equivalent to 40lbs of chassis weight removed. Which would free up approximately 2-4 horsepower (albeit the car would handle a lot better because of less gyroscopic forces).
