I was doing that for those that have dynoed their trucks, and have a number
to reference.
RWHP * 100/(100-drivetrain loss) is roughly crank HP in an auto. This
yields the gross HP that needs to be fed.
Numbers that have been tossed around for drivetrain loss that I know off the
top of my head are 15% (NV3500) and 23% (46RE).
Or am I off base?
