Hp. vs. Weight

Hp. vs. Weight
If my 97 Gt has 215 hp and a 99 Gt has 260 hp, but the 99 weighs 600 pounds more, can you equate how much that "lowers" the Hp. on the 99? I'm speaking relatively here, I know the Hp. still stays the same.

But to your original question, while its far from accurate, i think this is what your looking for:
100 lbs = .10 second in a quarter mile
.10 second in a quater mile = roughly 15 hp
100 lbs = roughly 15 hp
So its equivalent to 90 hp difference in the two, but franky it doesn't work like that

Don't ask me where I got it, but I read somewhere that for every 7lbs lost of a car it frees up about 1hp...

No weight reduction will "make hp"... you might get the same result from losing weight as you would adding hp.
generally, in cars that run 12's-14's or so, 100 pounds, or 10 hp, SHOULD equate to about a tenth, or .1, of a second.
This is all general though, there are many factors to a race that can offset 10 hp, OR 100 pounds or both, for instance, a worse 60'
