Robert, I just wanted to say thank you for sharing all of this. To an Engineer (Civil, but nonetheless still possessed of the engineering mindset), this is as fascinating and enjoyable to see as anything I have seen in a long time. I can only imagine how enjoyable it must be to create some of these pieces and see them installed and functional. Immensely satisfying.

Thank you again for the continued updates.

Though the picture is not great, this gives an idea of the new rear anti-roll bar made from carbon fiber and titanium. All parts are very carefully engineered for proper strength and flex and minimum weight. The titanium parts are "printed".

For an "old" car, the 964 is becoming increasingly modern.

Indeed it is! Thank you for the update. Can you reveal the wt. reduction with that bar?

also, I lost track of what muffler you finally went with... the CF/Ti piece didn't work out and you were considering inconel (?)

The original rear anti roll bar was approximately 9.4 pounds. The new one is approximately 1.9 pounds. As to exhaust/muffler, the final configuration will not be determined until after the four valve engine is completed and either works or doesn't. My guess, however, is that the headers will be incolnel and the final muffler will be titanium and carbon or titanium and ceramic.

BTW, the original front ARB weighs approximately 15.3 pounds and the new one is expected to weigh approximately 2.5 pounds.

Printed hollow or solid Ti portions, I assume hollow C portions?

Love those mathematical shapes.

Short update on 4 valve engine progress is that we have ordered the parts for the first test engine and hope to have it running on a test bench by November.
