yes, however before we get too carried away we should remember rpm, all these savings were talking about only really start to add up at very high revs, pheonix might of found 13brake @ 8,200 but i bet at 6,000 the gain is only half that, and probably only a quarter at 4,000rpm, i think your find frictional losses are like aerodynamic drag, they go up at the square of speed.
