Glad to hear you're still around Bob.

The test headers with the original carbon fiber/titanum muffler mounted on a test engine. When the test units are completed, they will be dynoed with the test engine. Assuming satisfactory results, they will be scanned and a rapid prototype will be created. In turn, tooling, including molds, will be made and everything from the engine block through the tail pipe will be made in a ceramic material used in military applications and that can withstand 1200 degrees C (2192 F) constant, that weighs aproxmately 1/4 that of steel and less than half of titanium (we should save a bit more with elegand design) and that has superior heat insulation properties to steel or even titanium.

Wow...just wow!
Thank you for the wonderful pictures.

Whatever happened to your carbon fiber primary muffler with the ceramic coated and laser drilled pipe? Did the muffler hold up to the heat cycling and maximum temperatures?

The carbon muffler was made of a material capable of enduring approximately 300 C (572 F) and was combined with an insulation material. Having said that, during the development of the engine, I was also working on a potential military vehicle and, in this connection, came across a material that can take 1200 C. As a result, the entire exhaust system, from the head to the tail pipe, will be made of this material. As such, the carbon fiber muffler saw only very limited use, i.e., not enough to say it was sufficient for constant and continued use.

From the Porsche Facebook page: "Icon of its era: this 911 „American Roadster GS“ was a one-off car for a US collector."

I must confess to being pleased to have this car called an "icon of its era". Having said that, I am even more pleased that, through the work of good engineers around the world, the America GS, though more than 20 years old, has a power to weight ratio better than a Carrera GT, better than a Type 997 GT2RS and better than the upcoming 918 Spyder.

Very impressive Robert, and this with a cabriolet too.

And if I get my last wish and we can engineer pneumatic valve springs into the engine the resultant HP wll give a power to weight ratio even better than that of the Bugatti Veyron.

Not sure if a link to FB will work here, but those that are on Facebook, check out the post on: A story from the past: the last ever built 911 Turbo (Type 930)

You need a "Last 930 Consolidated Thread" Jamie, then Bob can tell us what exactly was done on the car :typing:

Maybe some pics too.

Sorry, I don't have enough details on that one. Just what Bob told me over the phone some years back, and I was not taking notes :)

What information would you like?

Info on what was different on your car as compared to other 930s. We got the running commentary on the 964, so something like that would be extremely interesting too.

Thanks
Andrew

The list is too long to put up.
