GTR-TT,

You wouldnt need that CAD drawing so you can figure out where all that twin turbo plumbing is going to fit for the TOP SECRET TT engine would you?

Nah, I have got an offer from a proffesional chassi designer to do some stress/flex simulations. I wan't to know that I make the chassi better without adding more weight then needed.

I doubt it is something that they would give out since so many people keep trying to copy them.

The only way I can see that you're going to do that is to buy a chasis from Ultima, then CAD it yourself. Ultima aren't going to be daft enough to give drawings of their chasis to some random guy.

The only other way is if you know somebody who has justtaken delivery of a kit, and will let you measure it before he gets going on it. It won't take too long to do, as it's pretty much all straight bits.

I think you'd have to butcher it a little too. The wall thickness may vary from tube to tube, depending on strength required etc. You would also need to know the exact alloy / steel used as well. I've seen a bit of Finite Element Analysis at fords btw - pretty clever stuff.

I think that they use the same thicknesses throughout. Ithink that they'll tell you what material the chassis is made of if you ask them. It's part of the sales process. That shouldn't be an issue.

It's all done with vectors you know.....

Hi Mikael
I was also interested to find more info on the GTR chassis so I made stiffness measurments of the frame
and added braces where it was flexing the most.
The stiffness was improved from 3300 ft lb/deg
to 9500 ft lb/deg. All this is outlined, step by step,
at www.ultimav12.ca
I hope the info is helpful

That V12 ultima is unreal. Never seen a 'kit car' built so well as this before. It's more like a real supercar.

Actually most "real supercars" are slower

I already have a GTR from Ultima (delivered jan 2003). I would never dream of making a Ultima chassi copy, I just want to steangthen mine a bit to make the suspension work better. A stiffer chassi will make suspension tuning alot easier.

It's a shame you didn't think of it before you put it all together then In which case, you'll have to find somebody who has just bought a kit, and go and measure theirs before the build it.

I know you don't want to copy the chasis, and you know that you don't want to copy the chasis. But does the factory want to have a CAD drawing of their chasis flying round where it might be seen by somebody who does want to copy the chasis? I doubt it.
