I just went through every page of Roberts build----I wasnt ready for that.
I have been obsessed with rauh welt, and ap forever now....I honestly havent seen a build, of ANY car that compares to what he is doing there.....im speechless, wish I could see that car in person

Yes, the America GS has a Tiptronic. But, then again, it is a unique Tiptronic in that, when put into the "Tip" mode, it has no brain, i.e., it only shifts if the driver shifts. In other words, you can hold it in any gear as long as you want -- and its is a Tiptronic with a limited slip differential. As to America GS vs. Turbo S, that is a personal preference -- and I have always thought that Rolf Sprenger's Turbo S was among the best cars Porsche ever built. Having said that, with, in its final form, approximately 450 HP and 450 Nm of Torque and weighing less than 2200 lbs (1000 kg), not to mention unsprung and rotating weight significantly less than the Turbo S, a far better braking system than the Turbo S, 4-way adjustable dampers and other adjustable suspension components, etc., etc, I suspect that the America GS is at least worth of consideration.
P.S. The Type 964 3.8 RSR was a great car and the Turbo LeMans GT even greater.
P.P.S. Looking to see if the LSD can be a bit weight reduced through the use of titanium.

Nothing wrong w/a Tip...I loved the one that was in my car. If I could have had it set up like Mr. Linton's I'd probably have kept it. It would certainly handle the HP. I tried to find a suitable Ruf EKS, but was unsuccessful...I'm a left foot braker....two pedals suits me just fine.....
Robert, your car is truly art...you guys make absolutely lovely bits and bobs....and your engineering seems nothing short of brilliant.....coming from the racing world, I can say, conservatively, you must have a half million USD in design, fab, Ti and carbon in that thing...stunning!

OK, Robert I think we all know how you got the weight so low...
Can you give us a little info on how you got to 450 HP? Don't think I've seen any detail about this... Is it still 3.6 liter? Still N/A?
Not expecting every detail - but would like to know at least basic build spec...

You are correct, the power to weight ratio would be better than the CGT. As to how to get to the weight, engineering, engineering and engineering. As to the engine, it has been a 3.8 and now it is going to 4 liters. And with engineering (on both sides of the Atlantic -- full story to be told after success), we should get to approximately 450 HP. Finally, if we took easy weight out and, for example, did the doors, fenders and roof out of carbon (ala CGT), not to mention the seats, we could easily get below 2000 lbs (910 kg).

Because the project was to learn about a variety of things (e.g., designers, engineers, materials [composites, metals, coatings, adhesives], production sources) and doing these parts in carbon would have accomplished very little other than additional pure weight reduction after all else that was done.
