$603k for CS on BAT! Has this world gone Batty?

Curious me...
For valve springs, what can be done with their "position" on assembly to get more performance?
For better machining and polishing of surfaces, is this a thing where they changed the finish specs or do they have a black box room/process center where the workers in there put out a higher quality product using better machines and techniques?
For blueprinting in a production environment, are you saying that they put more checks into the CS engine assemblies? ...to meet the F131 engine specs?
Trying to learn more about the brand, thanks for any reply!

 

Was he asking how to get an "OWNER" badge in F-Chat? lol

Yes, I too appreciate the interest.

So many years ago when I read the factory broadcast on this (Challenge Stradale engine) I too wanted clarification on valve spring positioning... At the time I was in the height of my engine building period (Porsche hotrodding) and this interested me to no end. I was (and still do) using titanium valve spring caps / keepers and was well versed in the gains of lighter & matched bits for rotating assemblies etc. So, intrigued I looked for the answer. Without going too geek here ~ perhaps you know the valve spring height on a racing engine can be adjusted for gains, including gains with change in spring rate etc. Assuming translation to English, I think that may be what was implied by the factory description. I could not find any data on Ferrari actually moving the angle or location. So... That is most likely it.

As for polishing, this is a hotrodding bit that has produced results from way back. The polishing has many facets that give performance, including better windage resistance, and strength to the metallurgy from the polishing procedure.

Blueprinting is the final wizardry that does not actually add power, but it makes so that the engine has less power loss while rotating. To clarify this means that it actually has less parasitic losses (from the weight minimizing & matching of internal parts) so that its final output is higher then that of a similar engine with lower tolerances. In general terms the engine does not have to fight as hard to make power. Making it a more efficient (more powerful) unit.

The Challenge Stradale. Ferraris factory hotrod.

 

Bummer, I was fairly interested in at $395K, but when the price changed to $495K I gave up. It is a gated conversion so couldn't really figure out how that would affect pricing.

 

IMO that was for your offspring to deal with...if they turned out to be car people!

 

My 17 year old niece is car obsessed. I had nothing to do with her upbringing, she moved here a year ago and now all we do is cars (two Miatas, two BMW Z4s, two Ferraris). This was a car we were shopping together. We currently have three manual cars (1990 Miata, 2003 Z4, 2025 Z4). This car checked a lot of boxes for us. We will restart our search next year.

360 CS were much more special cars than people think.

The best way to summarize the cars is that CS started out in the motorsport department and then they added things to make the car slightly more comfortable and street legal etc...

Do not confuse this with the scud or Porsche approach which is given the customer less and charge more.

The CS was actually a specially developed car from the motorsports department. The engines had significantly more attention put into them. They were probably some of the most scrutinized engines ever assembled for a production car with 1300 units. They received a ton of extra attention and were truly race balanced and polished and blue printed. If I remember right the f1 dept lent a hand but can't remember what to be 100%.

They received many bespoke parts in the engine bay and if course the suspension/springs etc... body work... Thinner glass etc... Enzo brakes.

After the commercial success of the model Ferrari figured out people didn't really care too much about that stuff and were able to dial back some of the pain staking hand touches and really crank out profits on scuds and speciale etc ...

While people hold the scud and speciale in super high regard and value...

Honestly if you want to talk about specialness and special care of a mid engined v8 Ferrari... Nothing comes near a challenge stradale in terms of unique Ferrari magic being rubbed into the car.

By comparison the scuds and the speciale and on are really just marketing exercises to part rich guys from their money.

I'm sorry scud guys. I do love a scud. They are absolutely fantastic. It doesn't make your car less awesome. It's just the challenge stradale is something that really was never repeated as far as the motorsport departments involvement.
