As I wrote to my friend Hartmut Kristen this evening, "As, for years, we have talked about weight reduction and weight optimization, enclosed is a titanium part that, though, at an even greater extreme, could have been made of carbon fiber with a bonded titanium insert, might amuse you." Yes, perhaps I am getting lazy, only titanium speed clips.

Are you planning on redoing those covers in a lighter material? Those boxes (with all the internals) are heavy...

Those were done especially for me -- we'll probably leave them alone.

And times many hundred Speed clips :)
I think underestimated my workload bob I'll ring you back tomorrow

Wow, you're a pretty insane boy ;)

Just curious: I went through the thread and didn't find anything about the final weight of the car.
I would have dreamt to have a partner like you when I was racing... that would have been a blast.

Did you plan on replacing the steel sheet panels with glued composite ones ?
After a brief study I determined that it was cheaper and more efficient than to replace whatever you can with composite/titanium parts. I use regular racing parts (magnesium, aluminum) but invested about 10 thousand USD on the chassis to get rid of almost all the metal panels and the savings (weight and money) is much worth it. Also the car is extremely stiff, because of the large (1 inch) honey comb that has been used to mold the panels.

Now, it's certain that my car doesn't look like yours (from far).

Congratulations, it's an exceptional quality of work!

Present weight of the vehicle is below 2200 lbs. Final will be a bit lower. The steel panels were not replaced with composites because that would not have furthered the R & D aspects of this endeavor. Should this and other "easy" things have been done, the weight could easily be below 1800 lbs (with air conditioning, leather, stereo, real seats, Tiptronic, etc.).

yeah...
You should use my chassis then :)
It's not fancy like your car, but is really stiff and damned light.

I love your drive trains. Beautiful job !
It's funny how the work from motorsport always looks so drafty (have you ever seen a factory race car?? The interior and the finishing are always atrocious) while your car looks more like some Bugatti stuff : everything has to be beautiful.

Congratulations, again.

For several years supplied parts to Porsche AG for factory race cars (do not do so currently because reduced numbers of cars and price rather than better quality compromise). So I know well what they look like. Have also done quite some work with Bugatti -- the leadership of which is truly dedicated to quality.

Also race cars at Porsche has become a real juicy business, they make a lot of money on that and let private teams win for them, while they used to build factory owned racing cars. I believe the last one has been the 98 gt1. This means that it's been ten years now that track Porsches are tuned production Porsches. This also explains why Audi wins every year.

The titanium torque converter marches forward.

Awesome, as always. May I just forward you my christmas list?

Can I PLEASE see the whole thing?
