what manf. techniques were used for the CF? those are not Fiberforge pieces, are they?

Nothing to do with Fiberforge.

Robert,

If you make everything out of lightweight materials that can be lightweight materials...what do you figure the final weight will be?

Rob
Magnificient work. Any updates on your work ?
Im sure we are all waiting for more tasty pics and updates.

INSANE

Ok is any of this for sale.....drool!!!

The short answer is "No"

the GS is an engineering exercise into what is possible for Cartridge LTD. It is not to produce 964 parts for sale. rather show what can be done in the automotive sector across many applications.

that said cartridge does produce select items for sale however the volume is truely limited and none of the parts are for the 964 platform (Axles for the 996/7 Cup/RS/RSR series, 4 way shocks for 6/7 platforms, etc.)

Bob may have changed the model as well, so i cannot comment on a stock parts list, but cartridge LTD. is an engineering company and not a parts supplier per say.

Bob feel free to correct me if i am wrong here.
(i can claim in transit jet lag as a wait for my flight from Bobmay to Sao Paulo)

A fascinating exercise in material science! I'm assuming that many of your discoveries (on materials) are shared with the factory so that they can also benefit from it. The only issue I would find with that is that since the vehicle really isn't driven then the wear aspects of these changed parts are never challenged sufficiently to know their actual utility in the real world.

Beautiful work!

Porsche is a Customer (as well as other top level Automobile manufactures) of cartridge. however they are not given free of charge since this is a business, of course.

On the testing question- Structural / Wear components have been thoroughly tested to exceed the standards set by the customer (for instance Porsche). critical parts on the GS (brakes and engine components for example) are tested to the same or more stringent levels than Porsche (Many on the Porsche test benches) In this Cartridge is a Client of Porsche, utilizing its testing facilities as well.

As far as real world examples goes, cartridge Driveshaft’s (with ceramic bearings, Ti, etc) have been used and proven more durable than the factory parts in racing in the US and Europe (including 24hr races). Dampers are in Use as well for various marques as well.

The Components for the GS were made to a level exceeding what would be required for in a 24hr race (LeMans)

Bob, let me know if i misspoke on any of the details

Fantastic! It's good to know we have such world class engineers out there in NC!

NYC - Bob is the head of engineering and product development

I shoul mention that Bob Owns cartridge Ltd and is the driving force behind i as weññ

Hello is Bob's car closer to completion as of yet?
I met Bob I guess about 17 years back at a swap meet where he had the America GS Roadster and his
black 1985 BMW M6 w/21 miles both delivered on a trailer to the meet simply for people to ogle and gawk.
I recall being a might pissed because at the time I also had a black '88 M6 and felt anyone who chose to own one of those cars no less the porsche without driving it was very,very eccentric and missed the
real reason for it's existence....
Oh yeah the America GS Roadster was exceptional even back then but the turqoise and purple color
scheme left a lot to desired..
just my .o2 Bert

New throtlle bodies.

Wow!

It must be fun making this stuff!! :-)
