Heng, if you read what ferrari have to say about the F50 engine,
it is no exactly like what you have discribe. Isnt that abit
misleading?
Quote : The second important area is the F50's much acclaimed
'Formula One derived' engine. This is based on the 3.5 litre V12
unit which powered Prost and Nigel Mansell in the 1990 season, but
it's relations are loose. The road going powerplant took the F1's
65-degree vee, used the same 5-valve per cylinder design, and
retained the block length. Everything else, however, is different.
It had to be - although the F50 is a remarkable car, the
requirement to replace an engine every 200 or so miles as in an F1
car would be ridiculous! Some of the exotic materials have made it
onto the road engine, however, with titanium playing a part in the
internals. The capacity was increased to 4.7 litres, and the engine
hits the rev limiter at 8,700 rpm, quite some way short of the
14,000 attainable with the F1 engine - pneumatic valve springs made
such revs possible, but these were too unreliable to be used due to
air leakages (which have been often seen to cause problems in
Grands Prix), and were replaced with steel springs for the road
engine.
