512TR Autobahn Undertrays - Any interest

I think as seldom as we are ever able to go triple digit speeds and all the additional heat US cars generate and the amount of airflow those will reduce, and with the hotter temps in much of the USA and the traffic we have on average you are better off without them.

Ferrari did not leave them off US cars for no reason. Ferrari does their hot weather long term durability testing in the US for good reason and changes made to US cars is usually for equally good reason.

 

Are you sure about their purpose and market designation?

Some are "valid for CH, CH and AUS, and not for USA, CDN, J".

 

Good catch. They are for noise reduction, not aerodynamics.

Switzerland has the most strict noise regs in the world, and I guess Australia is right there with them.

 

Australia.

Austria is AT.

 

After I thought about it for a minute I remembered that.

If you scan the page many of the other items are noise insulation too. To the best of my knowledge Switzerland started the noise standard method of measuring noise driving down the road so sound insulation over and above just quiet exhaust was the norm there for a long time.

Thanks for questioning it. I knew of their existence, had seen pictures but never looked them up to know what they were for.

 

Australia and Switzerland use the same precats we do so they must be designed to be compatible. I have no doubt the early precats would interfere but these panels were never used on the early TR.

I have something like that on my car, but it's clearly aftermarket and it doesn't have a hole underneath. But it obviously makes sense, because it is installed mainly for protection of the sump. It was installed by the previous owner in Switzerland. Something like this can be very easily be made, by my opinion.

that looks like aluminum checker plate in 2 mm? ( in german: alu-riffelblech or alu-traenenblech )

 

Genau

 

I think the swiss owner did this because of oil leaking. the swiss technical controle ( MFK - motor fahrzeug kontrolle ) is very exact and they not tolerate oil at the engine or gearbox or elsewhere oil on the car

 

No idea, I see it as an extra protection underneath, so I left is as it is.

 

Turns out my Euro Testarossa has panels 23, 24, 25 and it's not a CH car. The Euro I had before didn't have them.

Was it ever registered in Switzerland?

 

Not that I know of.

Not going back on though. Might make for a more modern undercarriage but they just collect stuff and cover the rear lift points.

They do have some insulation on, probably some nice asbestos.

What is the piece of tubing between the transfer case and the gearbox? I know some cars don't have it. The transfer case overflows into the gearbox sump.

 

It was a tsb on later cars. The only thing that ever made sense was greater oil circulation in transfer gears. Never saw any issue in cars without it.

 

Brian, didn't Kent G have these on his car??? Somewhere in my fading brain i recall him telling me about it???

 

Have no idea. Based on how often his transmission blows up it can't be helping.

 

I am looking the under tray show in the picture in the 1st post

 

Hi All

The undertray marked in the first post is indeed for noise reduction. I have a Swiss F512M that for some reason did not have it fitted and, like turbo-joe says, the MFK is very strict in CH so I had the pleasure of getting one once it was noted as missing. I'm sure the car is significantly quieter from outside now...!
