150hp @ 1000. rpm = 787.8 ft-lbs
150hp @ 7400. rpm = 106.5 ft-lbs
150hp @ 74000. rpm = 10.6 ft-lbs

Sure is. This is the context of my reply, in case you missed it. The table, being of only 2 dimensions, is um... inconclusive.

Im not sure why but more boost = more power even though the overall cp is the same. My guess is that its less of a fighting force as the piston comes up so less power is waited on the compression stroke. More power in boost less power out of boost. |
