HP and Weight, this might be a little confusing Options

[celicarocker]

this whole theory is going off something i remember someone saying before. not sure of the exact numbers, but it was something like "every 125lbs you take out adds 4hp" or something like that. anyway, the point is there is a direct correlation between weight and HP.

now onto my main point. people talk stuff like "car A will beat car B becuase they both have the same HP, but car A is lighter" so if car B was reduced to the weight of car A, it would be faster? like if car A is 1900lbs and 150hp, and car B is 2700lbs and 150hp, wouldnt they both be the same speed? its like that old trick question "which would fall faster, a pound of bricks or a pound of feathers" where they'd both fall the same speed. so wouldnt a 1900lb car with 150hp go as fast as a 2700lb car with 150hp?

does anybody get what im trying to say?

think of it this way . most super bikes would smoke the hell out of any car on the road, yet they only make about the same hp as a stock celica does.

yes weight does matter a lot. many people do weight reduction mods, and they are a great idea, but the problem is that there is only so much that you would want or can strip out. you still have the weight of the chasis, the windows in the car and stuff like that, that you cant reduce.
