Stop in for a cup of coffee

Sounds reasonable. Torque at about 1600 RPM! Peak HP at about 2200 RPM!
no... the dyno wouldn't read low enough... thats all at 2200-2400 rpm... as a former Cummins engine truck puller with over 80 dyno runs, the peak torque on a Cummins is always between 1700-1900 with peak HP around 2100.. so add probably 10% to those numbers.
