[Land-speed] Rear Axle Question...

[23weldon]

26" tires, 2.14 rear 5% slip(0.95 speed factor) and 7000 rpm will get you 
240.5 mph.  5%slip with about 1000hp is probably the best you'll get with 
the hardest, smoothest salt.  It goes down from there.
Speed calculation formula:  Speed = RPM x tire dia in inches x (1-(slip 
percent/100)) / (336 x (ring&pinion ratio/quick change gear ratio))
Anyone who wants my spreadsheet email me.  It's a handy tool, especially if 
you have a variety of gear ratios available.  Any additional data points on 
the subject of slip will be much appreciated. Include car info, comments on 
course conditions, actual speed from clocks or gps, tach speed, tire 
diameter and actual gear ratio.
