911R Weight Reduction
#571
(1) There was something on the web that mistakenly said that the Porsche 919 (LMP 1 car) had a carbon fiber gearbox but that was incorrect. (2) Yes, the case/housing. (3) The carbon fiber gearbox (with titanium inserts) will save approximately 20 pounds. (4) As to "attempts to use hybrid steel/carbon-fiber gears inside the gearbox for further weight reduction", I am aware of discussions (perhaps even I have had some), though not only about steel/carbon fiber but aluminum metal matrix composite/steel, titanium metal matrix composite/steel, etc., not to mention the various ways in which each hybrid might be combined (put together). (5) As far as I know, today, the only race teams that have carbon fiber gearboxes are certain of the F1 teams although I believe that some of the Audi LMP 1 cars (R18?) had carbon fiber gearboxes. (6) Yes, none of this is "a walk in the park" but very few advances are, although, with the advent of electric vehicles, one might question the need for continuing development of traditional gearboxes, though I might question, for several reasons, whether or not electric is the ultimate solution.

Today, I had an idea. Instead of a crankcase made from a different material, I have given the go ahead to design and produce reduced weight titanium rods, lightweight high temperature pistons, a reduced weight crankshaft, titanium aluminide wrist pins and possible valvetrain upgrades. Together, they will have much more of an effect upon the 911R driving experience than a reduced weight crankcase.

Wow wow wow wow. This is dreamy. Are you raising the redline or re-gearing the car?
