Turner Engine Works acquired AeroMotion Inc. (AMI) in 1985.

-Thus, the AMI O-100 engine was renamed the Turner Twin Zephir.

-Very similar to the AeroMotion Twin as well.

-The Turner Twin Zephyr produced 53 HP at 3100 rpm and 55 HP at 3200 rpm with MOgas.

-Interestingly, other power outputs are given, such as 85 HP at 3450 rpm but with 100LL AVgas gasoline, and reaching 110 HP with a turbocharger.
