Can anyone tell me if any of the old cross-flow .40 Enyas had perry directional porting? A friend recently acquired an old cross-flow Enya .40
BB engine & it has more power than a 2000 vintage schneurle-ported Tower Hobbies .40 (plain bearing). Both engines are in good shape & the friction reduction from ball bearings is not large, so it has wondering how an old cross-flow can out power a modern schneurle ported motor.
