the 190a5 and a8 have the same engine.
the 190a5 is lighter
but, the 190a8 can push its engine to higher pressures so its faster.
above certien altitude, the air is too thin to maintain the higher pressure, so the engine powers of the 2 190s are the same and the lighter a5 pulls away.
atleast thats what i understand from the boards, feel free to correct me
