that's pretty old, but it's still really cool. i like the fact that 100rpm is redline, but if you go over it, you make 10's of thousands more horsepower.
that's big, but i bet if you got up close it wouldn't seem all that huge.
BTW, some guy wrote this Ferrari F1 book and it has many details about the engines and everything. the cars must weigh a minimum of 1323 lbs. ferrari adds 154 lbs of balast to bring their carbon-fibre tub up to that weight with driver!
their engine makes 804 (or so) hp at ~17,500 rpm, and a max of ~258tq at 15,500
the reason for that is the 41.1mm stroke. it's a 3 liter v-10, the clutch is 4.5 inches in diameter.
it uses electrohydraulic actuators to shorten and lengthen intake trumpets from 6000-18000 rpm, but they have to be quick because the engine accelerates at a rate of 25,000 rpm per second.
it's pretty rad. the book costs like 97 bucks, but i'd definately buy it if i had the dimes.

25k rpm/s with no flywheel perhaps. a few years ago i had an mp3 and webpage where one of the F1 teams (i want to say bmw, not sure) calculated the audio tone output by their motor at a givin rpm. they programmed the motor to hit certain rpms at the correct intervals to play "when the saints go marching in" by the exhaust note. acceleration/deceleration to the proper rpm's seemed instant
