Because, to actually put a running car on a track, particularly one with a lot of cutting edge (at the time) technology, at some point you need to stop all the intellectual masturbation and start cutting metal. A design that gives you 1sec per lap is useless if it never gets built.g-force_addict wrote:

You can safely assume it was blocking the exit. You can conclude that also by the fact that the Lotus 79 adressed exactly the problems you mentioned by channeling the diffuser exit to the inside of the rear tyres and by improving airflow into the sidepods:g-force_addict wrote:Isn't some air coming out from beneath the sidepods blocked by the rear tire?
Wasn't this creating a bottleneck as the airflow must turn to escape either between the rear wheels, outside of the wheels, or even over the rear wheels?
What does he mean when he says they took air from the side for the ground effect ?Marcus-F1 wrote:Beautiful interview with Norbert Singer, explaining how the aerodynamics were determined back in the day. Not an F1 car, but the 962 Porsche Le Mans race car. It was nothing more than educated trail and error.

The airflow pattern differs totally : when the Ligier is "extracting" air from below the venturi profile, the air coming out of the Ferrari is coming straight and only from the upper part of the venturi profile. Absolutely no air is being "extracted" from below the venturi profile in the T 4.

In reality the Ferrari 312 T 4 and the T 5 were bad ground effect cars because of the 180° V-12 engines. The 312 T 4 did well because of the dominance of the Michelin radial tyres over the Goodyear in 1979. Renault was the only other team with Michelin tyres that year but the Renault V-6 turbo engines had a poor reliability. One year later, Goodyear stroke back and the 312 T 5 was out of the game : 10th place in the constructors WC in 1980...
