Accelerometer

[Mike Chadwick <mchadwick@xxxxxxxxxx>]

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?
