Engine Mounts and Proposed Rule Change.
Posted: Mon Jan 23, 2012 12:36 pm
Thanks to Neal Bellamy for the heads up on the following which would make our engine mounts clearly legal if adopted.
SCCA proposed rule change, if approved would become effective 2013
The STAC is submitting the following rule change proposals for member comment:
- Replace 14.10.J with the following (#4128, 4837, 6431):
“Any engine or transmission mount is allowed provided it attaches only to the original mounting points, does not
relocate the engine/transmission (other than incidental to changes in compliance material), and weighs no less
than the OE mount. All components between the engine/transmission and the mounting structure are considered
to be part of the mount assembly.”
Also remove 14.8.E and re-letter subsequent sections accordingly.
Comment: The existing allowance attempts to retain bushing compliance through an ineffective restriction on
metal content. Mounts of a solid nature can still be legally fashioned from hard plastic (e.g. Delrin). The proposed
allowance replaces that ineffective restriction with one that instead limits weight reduction benefits.
