What I meant by the lbs per HP was to refer to a indexing method for full scale cars that shows how much power a car has based on engine power and vehical wieght.
As an example:
The Dodge Viper weighs 3300lbs and has an engine rated at 450 HP.
The Nitro 4Tec weighs 4.5lbs and has an engine rated at 1.25HP.
Take the weight and devide by the HP and you get the rating of "lbs per HP" ( Pounds per Horse Power)
This rating system enables buyers and manufacturers to rate any car based on how much it weighs and how powerful the engine is.
So the Viper is rated at about 7.3lbs per HP
And the 4Tec or GT4 is rated at about 3.6lbs per HP
To put it simply the lesser number means the faster vehical. Less weight to be pushed by each HP. Get it??
Figure a 140HP Yamaha R1 Street bike weighs 500lbs. With the Pounds per HP system you can figure about how much faster a motorcycle is than a car. The R1 is 3.5lbs/HP and the Viper is 7.3lbs/HP. Obviously the motorcycle is faster because its pushing a lighter vehical with a very powerful engine.
Anyway, I just want to get the really wide tires like the Viper or R1 has to handle all the power of the car. More power (lbs/HP) needs wider tires to float, right?
Hope no-one is confused...
