Power to weight calc

[bruce plecan]

ref Martin Hill:
  There used to be a Shareware version of DragStripPlus
floating around the net, (I forgot where), but it has provisions
for like 20+ car engine variables, and was fairly accurate.
Was sold by Martel Bros,Texas USA.  I used a version,
and fudging 2-3% on torque converter slippage, numbers
were actually close.  Anyway this might be a accurate
way of quessing which way to go.
