weight vs horsepower
Does anyone know how much weight is equal to 1 horse power? for example, if your car weighs x amount of weight less/more it is the same as having 1 more/less horse power.

Re: weight vs horsepower (SwitchCabNine)
There is no answer to that question.
But I think what you want to know is....
How many LBS. must be accelerated by 1 HP.
Lets say you have a 3,000 Lb car,
and a 180 HP motor.
You would divide the cars' weight by the ammount of HP.
(3,000/180=16.666)
Each HP in this example would have to move 16.666 LBS.
Now put that same 180 HP engine in a 1800 LB car...
(1800/180=10)
Each HP in this lighter car would only have to move 10 LBS, so this car would accelerate much quicker.
And a 90 HP engine in a 300 LB motorcycle?
(300/90=3.333)
Real Fun!
So to accelerate faster, you need to either up the HP, or loose some weight.
All of those examples assume the gear ratios stay the same.
