After Reading the latest "top speed" article, I started to wonder about
the comment on 600hp at the rear wheels.  Maybe someone out there can
educate me on this subject.  I had always thought hp ratings for most
cars were at the flywheel, and that the hp at the rear wheels was
substantially down from the flywheel figure.  A case point is that my
motor is rated at about 200hp at the flywheel.  When the car was on
the dyno, the rear wheel hp was closer to 100hp!  What gives?  How
much does the drive shaft/differential design affect the relationship?
I'll post a summary.
