The R - A New Idea!
This week I had occasion to look at the engine/transmission of an R at quite some length. The more I looked the more I have been tempted to try something new -- a carbon fiber transmission case. Do not know if it can be done, but it is worth a try.

Wow. That’d be awesome. What’s the estimated weight difference?

My initial reaction was to question the thermal rates of dissimilar adjacent materials.
Wow, just looked, CF has a negative coefficient of expansion, but what about adjoining materials - can they get these sealed tight throughout all temperature cycles?
Since CF is not heat conductive and most aluminum gear boxes have fins because heat is a concern, will trans oil temps be OK in a CF box...or is forced flow through an oil cooler being used?
Very exciting stuff thx for sharing

While I would normally reserve the use of the word "awesome" for curing cancer, the end of world hunger or the birth of a child, as the last German car I can think of with a carbon fiber gearbox was the Audi R 15, if we can pull this off, it would be quite nice.

Loving the idea of some weight saving on my GT3, but only planning right now. I do need to phone my dealer to discuss warranty and exhaust changes as I am in the UK, with a 991.1 I need to be careful
Did you ever do a list of items with target weight saving estimate by item ?
My GT3 will be a keeper so would love to plan for an upgrade over time

Just curious Robert... Do you own a CF production company or are you funding the development of these parts third party? End game? Jus make your R lighter or a business? You obviously know what you are doing but wondering about the why given the cost to design and produce these parts.
