Your question is very parallel to the old LBJ:
Q: How many Surrealists does it take to change a lightbulb? A: FIIIIIIIISH! The only way you can convert lbs to HP is by throwing in length (feet) and time (minutes). Divide the weight in lbs by the length in feet and by the time in minutes. Throw in a term for revolution as well, and you have HP. Re-arrange it, and you get: HP = lbs/ft * R/min [ * 5252 to get the units right] Which is an obnoxious way of saying that your question has no real answer. Too many other factors for any one number to be "correct". For instance, take 100 lbs off of a BMW 7-series. Not much diff, huh? Now take it off of a motorcycle. Big big diff!! Also, lighter weight means less force required to accelerate, or decelerate, or turn. More HP does nothing for braking or turning, so at an autoX light weight is even more important than at the drag strip, for instance. --DD |
