don't forget about www.sscc.us for those with the need for speed.
FLAT OUT ON A PUBLIC HIGHWAY,nevada highway 318 (my choice)
or highway 278 (more turns) each one lets you go as fast as you can or
afford to go.

Ummmmm......BONNEVILLE. Get it? We're talking nostalgia here. The place where all land speed records are made and broken. (Since Daytona closed the beaches). The place our cars are named for, the place where the Spirit of Bonneville ran.

Some more information:
The drag coeffiecient of a 92-99 Bonneville (no distinction made between the different frong bumpers) is .360, and the frontal area is 24.3 Sq/Ft. At 140mph (breakout speed for the 130 class at Speed Week), aero drag is costing me 160hp. This doesn't seem bad, but keep in mind that heat is a factor also. I'm assuming that'* costing me 160 wheel horesepower, which is about 200 crank hp.
Now for gearing and such......
Using a gear ratio of 1:1 for the final drive (3rd gear since I'll never see OD), 2.97 gearing, and 225/60/16 tires, I'll be running at 5251 rpm'* to maintain 140mph. (757.63 tire revolutions per mile for those that are interested).

The calculator/formula I use determines the diameter for me by inputting my tire size. That'* ideal diameter, mine are obviously smaller now from wear, but I'll have new shoes on for the run. My H-rated tires qualify for the run, but I'm going to V anyway.
The only problem with calculating tire diameter from size is that most of them aren't exact and that the rolling diameter isn't acheived. Of course the only way to get rolling diameter at those speeds would be to know the wieght that wheel is responsible for, how much of that is unsprung, the weight of the thread...
But somehow I bet you knew that and you're just entertaining me....
