Larry Elison is a very lucky man indeed!

Hi all,
Not sure if it's been mentioned in here before, but I have been spending hours looking at this Cobra specially commissioned for the Oracle CEO.
This is truly a work of engineering excellence, if I could afford one I would have one tomorrow !

Just spend time looking at the whole project story from concept to completion, it's truly magnificent!
Enjoy!

Mmm, that really does not read like the thoughts of someone who understands material science at all. An aluminium chassis held together with bolts is going to get suffer terrible metal fatigue and crack in no time at all, and in wildly unpredictable places. Massively time consuming to make and pretty to look at really does not equal solid engineering.

that will be hopelessly heavy and vulnerable to stress.
Well Kirkham Motorsports don't actually state the weight of Larry Elisons car.But I am confident that it will be a lot lighter than the 2300+ Lbs of a normal 427 Cobra!
The other aluminim bodied Kirkham Motorsports 427 Cobras, are qouted as being less than 2000 lbs with billet suspension and all alloy engine!
I am just trying to work out now how much I could sell Tom and Lucy for to fund the $100,000 I need to buy one!
I for one think the LJE car is a work of pure car art, if I could afford one I would buy one tomorrow!

Ahh yes it is a nice work of art and certainly interesting.
Apologies if my post sounded a bit snooty.
No problem! Everyone is entitled to their own opinion!Apologies if my post sounded a bit snooty.
I just loved the excellence of engineering that went into the production of this unique Cobra!
I also think that some of the negative posts made by other people on here are not based on any real facts, more misinformation than anything else!
There is no reason to suppose to that the chassis will have an inherent problem due to being made out of bolted aluminium panels.
If the aluminium remains below its fatigue limit and the bolts are not loaded above their clamping load then there shouldn't be any problems at all.
It has to be the least economical and least practical method of car construction imaginable.
It is also an epic piece of automotive art.
I work on structures like this every day, big CNCd thin walled light alloy parts with bolted flanges. It made me think if a range of very ordinary stuff (furniture, light fittings, kitchen equipment etc) all CNCd with pretty isogrids on them would be a profitable venture.

The Kirkham cars are quite hit and miss when it comes to what is artistic and what is well thought out engineering. An example similar to the all alloy Cobra is this one.
The copper is heavier and has no benefit other than showing what the guys in Poland can do.
The Chassis in billet aluminium is flawed as it has no grain and is prone to fatigue. It is like chipboard wood. Extruding it forming it in a press is what makes it stronger and gives the metal a grain rather than playing with a CNC waterjet.
A titanium Ti 6Al-4av alloy chassis would have been better suited to their skill set and the chassis design of the Cobra.

Well, it could be argued that he must of been a reasonably lucky man to be able to achieve what he did.
I'm not going to argue that point however, the idea of luck is completely subjective.
It does sound slightly better than "larry elison is a very rich man indeed" though doesn't it
A lot of boat trailers are made with bolted aluminium, and none that I've seen have failed based on that issue. I guess aluminium flexes and so bolts aren't the best method of holding it together, but I'm not an engineer so if someone could clear this up that would be nice?

It's a very pretty thing, but it is not "excellence of engineering". It sounds more a like a few flimsy facts about car design thrown in a to justify a product that is needlessly expensive.

If designing a brand new chassis from Billet Aluminium, then engineering it in to a 50 year old design of car, and all the limitations that entails, I would like to know what your idea if engineering excellence is!It's a very pretty thing, but it is not "excellence of engineering".
