That is very true. I'm not sure the Lenco is less parasitic than a 904 (but, a five speed Lenco has to eat SOME horsepower; all those dragging sprags, but it enables the kinetic energy stored in the spinning flywheel to help,) but the alcohol over gasoline is definitely a factor; just how much, I don't know... But, it's a well set up car and makes good use of every available foot-pound of torque... nothing is wasted.
