I am currently searching for pictures from a race-going Ferrari. Even extensive googling could not help me further so far.
This is what I know:
The car was a private initiative, aimed at the armsrace going on with the "Silhouette"/IMSA cars, the Porsches 935 K3 and "Moby Dick", that were going to insane ends. It was not factory-backed, and I have a strong conviction the car was initiated and driven by Gianpiero "Momo" Moretti and his then usual professional top-driver, also an Italian.
The only appearance of this car I seem to remember is on one of the 24hours of Daytona races; and its concurrents/specifics place it in the early 1980's. In this race, it caused quite a stir (which is why I wonder that I can't find pics of it), as it qualified more than reasonably, and then blasted off at a horrendous pace at the start, leading all the K3's and others for about 6 laps, before something gave in, and it had to retire.
There is no doubt it was a turbocharged car, and memory made it an offspring of the 288 GTO, but this is highly unlikely as that would place it several years later, so an outbuild of the 308/328 G4 is much more likely.
I do not know about any later appearance, though a more USA-oriented career is possible. The appearance of Group C cars made it more or less obsolete anyway, and Momo Moretti went to other things, before returning with his famous 333SP and other co-drivers.
Anybody there who knows what I'm talking about?
Thanks for clues, Joris
