Just to ensure you understand, the chart on the left is hp, chart of the right is weight. At 150hp (120 stock) the lap time difference (same weight) is 8/10 second per lap; at 200hp (160 stock), 1.2 seconds; at 250 hp (200), 1.6s.

Given equal 200 hp (160 stock) a 2500 pound FWD car would need a near 200# weight advantage to make equal lap times. And, this assumes a 60/40 balance; I'd *kill* to get my FWD car near that value (most are 80/20).

You don't consider that significant? I most certainly do.

But why not use weight? Keep in mind that since we set weights based on horsepower, we can only choose one variable from which to derive subtractors. It's my position that the base assumption from which everything else is derived, horsepower, should be the factor used.

That's some big numbers, Andy, and supports exactly what I've been trying to convince you of for a couple years...[/quote]
