TRI60

Here is a photo of the rear differenyial from a TRI 60. It was also used in the TRI 61. I have done work on both so I a could be mistaken and this might be from 0794.

Picture is from TR60 DiDion rear end

 

You are correct. Now that I look closely I see the provision for the sliding block for the DiDion tube. This is from #0774. The TRI61 used a very similar case. I am trying to dig up a photo from it.

Only the factory TR58 had transaxles and all were RHD. To the best of my knowledge no TR59, 60, or 61 had a transaxle.
Customer TR58s were LHD and had a live rear axle.

 

Hello Derek,
I'm fairly sure the trannys were behind the engine in the front not in the rear of the car. However in 1960 they had 2 types of rears. The "I" in TR"I" was supposed to stand for independent rearend. But not all cars had them. Some had the independant rear, some had the de Dion rear. The wishbone independant rear was the same as the GP cars and that is what might be confusing you. But the trannys were on the backs of the engines in the front as far as I know.

There is some good info about these cars on page 70 of the book "Ferrari, the Sports and Gran Tourismo cars" by Fitzgerald, Merrit and Thompson

Thats where I got the info from

I agree completely!

 

746 started life as a 6 cyl car (296 Dino) in 1958. It ran one race as a factory team, Siverstone, finished 3rd. In 1960 the car was redone at the factory to a V12. It was transformed to a TR60 with 532D trans mounted behind the engine and a 532D De dion diff as per TR60. It was built "after" all the team cards were just about thru with there racing cycle for the factory.It was formally consigned to Chinetti 14/Maggio/1961 as a "Bastardi" TR60

 

Thanks for bringing this up. Do any cars currently exist in the TRI60 configuration?

 

i believe all the TRs had outboard brakes.the cooling of drum brakes is vital and inboard brakes were difficult to duct and they were also subject to heat from the transaxle. the pontoon fenders created by scaglietti were designed to increase the air flow to the front drums. on slower tracks all was fine. the problem was at speed over 150 mph [like the mulsanne straight at le mans].the air flow inside the pontoons would start to produce lift which caused the steering to start to loose control[needless to say the drivers were not to happy with this]. that is the main reason why so many of the pontoon cars were rebodied. the factory cars used the transaxle mainly to transfer some weight from the front to the rear. also the dedion tube suspension designe made it easier to install outboard breaks and also improved the handling required at such places as the nurburgring, the mille miglia and the targe florio. it took a lot of design/testing for mercedes to develop a workable inboard rear brake system with there swing axles in the 1954/5 formular 1 and the 300 SLR cars. george [email protected]

 

0780 - I have read on this site in another post that 0780 might not have been converted to 0808. In fact 0780 might still be "out there" unlikely but possible.

0782 - many years ago, mid 80's, I read an Australian magazine where a letter to the editor was printed and the writer of the letter claimed to have seen a 250TR59 or TR60 in Australia and the only one that fits is this car but then again maybe it was a fake.

So as with most anything Fcar the facts are as clear as muddy snow.

We recently toured a local collection, The Pat Hart collection, and I couldn't identify one Ferrari with a Fantuzzi body, so I asked fellow club member, Kerry C., who is far more knowledgeable than I about it.
Here is his reply.
Darned facinating stuff!


The 250GT SWB Fantuzzi bodied Berlinetta has a long story, involving two
chassis and three bodies. A 3 liter Testa Rossa, S/N 0780 was raced
extensively in 1960-61. In 1962, Ferrari installed a 4 liter engine in the
car and re-numbered it 0808, with Fantuzzi rebodying the car as a roadster
with a rear airfoil and a wraparound windshield. Won Le Mans in 1962 with
Hill/Gendebien. Rodger Penske set a lap record in the 1963 Le Mans race, but
then broke the motor which sent the car into a bad crash. Fantuzzi again
rebodied the car, S/N 0780-0808, but this time in the Berlinetta form seen
in the Hart Collection display. Pierre Bardinon bought the car and had it yet again
rebodied into the first Fantuzzi (LeMans winning) form. The Berlinetta
Fantuzzi body was then placed on a shortened 1958 250 PF coupe chassis S/N
1087 by the Fantuzzi works. So the car has a 1964 body on a 1958 chassis.

I am quite confident that 0780 did not become 0808 as has been frequently reported. I examined 0808 quite carefully on behalf of the Classiche Department, and there is no sign on that chassis of the changes (including welds) necessary to convert the three liter car to take a four liter SA engine. Additionally, during the course of the inspection, the department discovered the order for the (new) chassis for 0808, placed with Vaccari in March of 1962. So, 0808 was a new car for LeMans in 1962; 0780 disappeared after the Targa accident and may well have been destroyed. 0782 is believed to have been destroyed as well, but it does remain a mystery.
