 I recently borrowed an accelerometer from a friend (I don't have the model
 with me, I know it is supposed to be a very good one, about $800) and made a
 few runs in my 635csi.  It calculated (among several other things) 210
 horsepower at the wheels, simply by entering in vehicle weight (plus 60lbs
 for various trunk junk and 220lbs. for my oversized butt)  How accurate can
 this be?  Wouldn't other factors play in, like aerodynamics, gear ratios,
 diff ratios, shift points and/or driver skill, etc.  Does anyone have
 experience with these devices?

I would sujest that if it measured 210 hp at the wheels it's prolly not very
accurate.
