Just curious to know.

Euro/Asian cars tend to make their horsepower at higher revs at the sacrifice of torque. The smaller the displacement and the greater the number of cylinders generally result in less torque. American cars have always been Big cubic inch motors in relation to their horsepower. Big displacement equals big torque. The Torque and horsepower curves always cross at 5300 or so RPM's on a dyno(I forget the exact number off hand). Torque is what you feel when you drive and tip into the throttle. More is nice.
Dry sump oil systems may have some reduced losses due to the fact that there isn't oil being thrown about the crankcase to slow things down. Porsches, Z06's are both dry sump systems.
