Alright, quick check on both recommendations...

ROB, on the graph below, but peak RWHP was around 6,100rpm... MAF airflow in lb/min = 86.69 * 10 as a representation of crankshaft hp would equal 866hp at the fly which seems pretty far off... seems alot closer to WHP... thoughts?

Now testing; Engine Torque (taken from "Delivered Engine Torque" or "Engine Torque" VCM channels) x RPM / 5252 (constant #) = CHP
Then applying the Drivetrain loss depending on Transmission type, Auto / Manual to get the R-WHP/TQ...

Peak torque is at 4,500 rpm... Delivered was 640ftlb and Engine torque was 878ftlb...

Using your model...
Delivered 640 x 4,500rpm / 5252 = 548hp
Engine Torque 878 x 4,500 / 5252 =752hp

Seems like all of these are off... unless I am doing something wrong...
Thoughts?
