magazines reveal a marked deterioration: the maximum
power to the wheel now appears to be of only 24.46 hp at 9750giri against
27.68cv to 10250giri at the time recorded on the previous F Even the maximum
speed is affected heavily with a peak of only km / h 146.350 against 160.3km / h
achieved by F. Only in the tests taken in the 400 meters to 50km / h, the IFI
shows a slightly better performance with a time of 19.487 seconds at an output
rate of 94.750 km / h (20.639 sec 91.550 km / h). Interestingly, however other
magazines took over not too dissimilar to the performance data obtained from the
previous F or a maximum speed of 160 km / h. It ‘probably some IFI supplied to

once again takes a leading solution and borrowed directly from the racing
department. The valve, split due to the adoption of a stud in the exhaust
manifold, and ‘controlled by an electric motor that receives the order to open
