We get questions about the compatibility of SDS EFI and EI systems with a/c equipped engines.
We are not compatible with factory Lycoming twin sheave flywheels.
We are compatible with the Airflow Systems serpentine drive flywheels and have a CNC'd drilling jig for these.
As well, be aware that the standard, one sheave flywheels supplied on new Lycoming engines lack the 12 tooling holes to mount our drilling block. In this case, best to delete the flywheel if it's a Thunderbolt engine and order our billet flywheel with the magnets already mounted.
