    anybody know anything about F1 cars? I was just curious what ferrari does to make so much HP with them out of a NA V10 3.0 litre. I realize that they rev high, but how do they keep the torque up that high? is it cam profile, ecu tuning of some type? a 360 is a relatively (for a roadcar) high rpm unit, but still, it's HP begins to fall off after a certain point, so RPMs alone arent what make the power...what is happening internally at those high revs? a SUPER highlift cam profile switch a la vtec?

    There are lots of things that Ferrari does to allow a F1 engine to rev and produce high power output numbers. Perhaps the biggest factor is bore to stroke ratios of around 3:1 this allows lots of air and fuel to be placed into the combustion chambers.

    Other items include reducing friction with engine coatings, Minimal piston skirt areas, very narrow plain engine bearings, Reduced oil friction.....

    The key thing to remember at 18,000 RPM Each piston is bouncing up and down 300 times a second In order to get maximum effect of the combustion process the piston pin is placed as close to the crown of the piston in order to park it at top dead center the longest possible time (Piston Dwell).

    There is not one magical eleiment that produces power it is the lumb sum of several items that causes the end results

    The most important equation when designing an engine is as follows:

    Money * Math = HP If you dont have a large budget do not expect a lot of HP like wise if you do not do the math do not expect a lot of HP either. This is why you see a lot of people throwing money hand over fist at a engine and it becomes undrivable or loses power. They did not do there homework.

    F1 cars don't produce that much torque, I believe it’s around 270 or 300 lb-ft. They produce a lot of HP but that’s based on the RPM. And in any case torque isn’t that important for an F1, they’re usually moving fast enough to rely on HP. Only time torque is important is off the line.

    The TQ of an F1 engine is pretty close to the TQ of an F360! And that is all that is possible with atmospheric air. Since the F360 has 20% more displacement, the F1 engine make up for its lack of displacement with A) compression, B) friction reduction, C) special gasoline*, D) breathing, E) exhaust wave scavenging. The distance from the air intake in the air box to the back side of the valve is only 6", is straight, has the perfect profile to allow air to accelerate into the combustion chamber. The headers are perfectly tuned for the power band of the engine. Cam profile has close to 160 degrees of valve overlap 340 degrees of duration, valve lift is close to 50% piston stroke, valves are controlled by pnuematic springs (3000 PSI nitrogen). Stroke is reported to be in the low 3x mm range (i.e. 1.3")

    *gasoline is a mixture of Tolulene, Xylene, and other exotic liquids. It knocks on the test engine at 101 octane, but operates in the race engine as 110+/- gas.

    What about the big killer-noise vibration what ever you want to call it they have to be rid of it,whats it like with unbalanced wheels on a 360 at 160mph not nice,so an f1 motor turning 19,000rpm is vibrating its heads off,
    ferrari 2002-850 bhp
    ferrari 2003-885 bhp so a gain of 35 bhp
    ferrari 2004-who's going to tell us then we know your there,
