The F50 Thread

Mine is there too at the moment, but only having a minor version of the same treatment Karim! James recommended wiring the exhaust valve permanently open (std system) for a good sound, would you agree?

 

Yes, Joel, I saw it since it arrived 1-2 months ago. Keeping the valve permanently open will give you the maximum sound the original exhaust can give (at all rpm levels instead of at only at the higher rpm), but no more. You will still have the sound damping effect of the original 4 manifolds, 2 converters, and 2 silencers.
As you like to drive your car often/hard, you should consider either a sports exhaust or straight pipes and then simply keep the original system in boxes.
So, three choices.

 

At what rpm does it open?

 

Joel - You might want to check a Capristo system developed 2-3 years ago for the F50 (for Kevin Johnson) facilitated by Scuderia Car Parts. I met him recently and he confirmed being delighted by this custom-made system (he had straight pipes before and I converted to them after a 2011 visit). But that was then, in today’s times it might be ‘too much’.

Bob - I guess around 4 to 4.5k rpm.

 

Hi,

the exhaust valves on an F50 are the same as used on a Ferrari F355 - the F355 5.2 Motronic uses only 1 valve, the F50 has 2 - one on each silencer. The danger with the original valves is if they fail - when they fail they do so in the closed position - therefore they don't allow the release of exhaust back pressure gases, and the catalysts get cooked - which is very expensive to source and replace.

I have a pair of as new F50 catalysts if this ever happens to anyone - contact me

If you use your F50, I would remove the original valves and store them, replace them with 2 new Capristo valves (just buy 2 valves for a F355) - if the Capristo valve fails, it does so in the open position so no danger with back pressure - the opposite to the original part.

I would also remove the 2 original F50 catalysts and replace them with straight test pipes - store your original catalysts and save them from further damage.

This will also give you a throatier sound, but retain the majority of the original exhaust system, give you a safer operating system with no valve failure issues, and save you a fortune in replacing the complete system with a sports system.

If you want more noise after that, replace the back boxes with a sportier option, if you want more noise after that replace the back boxes with straight pipes.

cheers Mark

 

Joel - so if you keep the valves permanently open as James suggested, then you will not have any potential failures mentioned above by Mark.

Very useful, thank you. Where is a good place to source the F355 Capristo valve - is that an aftermarket part or std?

I'm not sure what happened to the car that poor child was killed in a few years ago in the UK, Marcel may be able to give Chassis no. I think it was due to go through a major auction house before the accident

So basically all the information provided by the seller is inaccurate? I always had my doubts about that place...

Is the car any "good" Marcel?

 

ok, so no mileage discrepancy

 

Good afternoon;

I have similar information than Marcel, but with a few changes, as Marcel said it was delivered new to Emmanuel, but I have it as delivered through Charles Pozzi SA, Emmanuel is a Portuguese businessman, that resided in Portugal in the 2000s, close to the border with Spain.

This car was first registered with touristic plates in Spain in 2006 and finally in 2010 it was registered here (it was cheaper to register it in Spain than in Portugal, but the car resided in Portugal) on plates “4269-GXZ” in April 2021 it was sold to Switzerland, which is where it resides currently.

I can confirm that the car was in the same family ownership until 2021, as the person that sold the car in 2021 carried the same last name than Emmanuel, probably his son. Around the same time they also sold a Diablo SE30 to Curated in Miami (Chasis: 12112).

What I don’t know is what happened to the car between 1997 and 2006, it’s likely, as Marcel said, that Emmanuel lived for some time in the Netherlands.

 

Incorrect.
Not via Pozzi.
Direct sale by factory.
Netherlands, not Portugal. Not Spain.

Marcel Massini

 

Good afternoon;
I have confirmation from Ferrari that it was delivered via Pozzi, i can send proof via private message if you require.

¿Are you saying ZFFTA46B000106890 was never in Portugal/Spain?

 

I have confirmation from the factory that it was a DIRECT sale. SALE, not delivery.
A direct sale has ZERO to do with actual delivery. It can be delivered thru anybody on the planet.
And I require nothing.

Marcel Massini

 

Its a pity that someone with your knowledge answers in this tone to someone thats just trying to provide information to clarify the history of a car.

Not one part of what i said in my first message is wrong, i clarified it was "delivered through charles pozzi" never said it was sold new by them. The only question i had was what happened to the car in the first 10 years of its life, as i was not aware that the owner lived in the Netherlands.

As for the history from 2006 to 2021 i can 100% confirm that it was in Portugal and Spain as i've checked with the Spanish vehicle agency.

 

You may want to identify yourself first. Tell us who you are, what is your real name, are you a dealer? Broker? Collector? Journalist? Enthusiast? Owner? Or? Why do you need to hide behind an alias name?
You joined about 2 months ago and have 3 posts so far.
You may also want to re-read post #4016 again, where I clearly state "Sold directly by factory to first owner Emmanuel D. C. in The Netherlands.".
Not a single word from me about delivery.

And what is YOUR connection to #106890?

Marcel Massini

 

"HoyMatriculado" or in english "Registered Today" is what we are known as in Spain, which is the territory we know most about, we are 2 young (20 year old) enthusiasts that have compiled in the last few years a registry with all special cars registered in Spain, in Ferrari we have anything from Californias to LAF's to a 225 Sport Vignale Spider, we do work as brokers in some occasions putting in contact buyers and sellers, but i want to leave clear that we don't have any interest in this specific F50, we havnt transacted with it or provided Insider Auctions with any information.

We havnt participated in this forum because we didn't feel we had anything to say that hadn't already been said, until this morning when a friend sent me this thread and asked me about the car.

I completely agree with what you said in #4016, and what you said there is compatible with what i wrote down in my first post. Problem is, if you see message #4017 it leads people to think that this car was always in the Netherlands, which is not the case, as the owner was always portuguese (up to 2021) and the car spent from 2006 to 2021 in Portugal/Spain.

My only question, which i feel i didn't explain correctly in my first message, is if its 100% certain that mr. Emmanuel lived in the Netherlands from 1997 to 2006, as its a bit strange (although perfectly possible) considering it was delivered (not sold) via Charles Pozzi and the owner was Portuguese, that gap from 1997 to 2006 is where im not sure what happened.

I hope i've cleared everything up and we can discuss in a friendly manner from now on
