for typical automotive diesel, the torque curve is flat only in the

More rpm less torque...


This is a TURBO diesel, whick keeps the efficiency up for a wider
band. (and it's not hard to change the turbo if you need a different
"map"

You may reprogram the ECU and give a flat curve for higher rpms, it's
the way Thielert use to have a 135hp , 1700cm³ engine from a 95hp
automotive engine. Nerver over torque this type of engine but it may
over rev and keep long life.
