    How does Ferrari do it

    Ferrari in many of their recent cars like the 355, 430, 458 italia all use v8 engines. They are all N/A and fairly small displacement but develop a lot of horsepower stock. They 458 italia is up around 550hp using no supercharger or turbo. How are they getting this amount of power out of a fairly small motor. Then of course is that sound!!!

    He is saying relatively speaking 550 hp is a lot for a 4.5 liter V8. The reason they are able to do this is with the engines excellent ability to breathe air, it can move air into and out of the engine very quickly and with little effort, so the power is used to move the wheels.

    To do this naturally aspirated from 4.5 liters, 550 hp is not nothing, it is difficult for a production car. Cosworth, renault, peugot etc.. can make engines that make 700 or 800 hp from 3.5 liter V8s, those engines redline at 18,000 RPM. Ferrari engines uses similar technology in production engines which is why they can make close to 600 hp from 4.5 liters and 9,000 RPM redline.

    Those cosworth, lotus and other f1 engines are they still n/a or do they turbocharge them. If they don't turbocharge them what kind of tricks is there to get that much air in the engine. Can the head design be that special?

    dont forget about the HONDA S2000. 240hp from 2 liter = 120 hp per liter in 1999

    ferrari 458 - 562hp from 4.5 liter = 124.9 hp per liter

    GT3 RS 4.0 - 500hp from 4.0 = 125 hp per liter

    the head design is in fact that special. Ferrari takes a lot of pride in their head and camshaft design. They are also low friction engines. All of this costs a lot of money. People are paying ferrari for the pedigree of technology that goes into these engines, a century of evolution to what are the best and most efficienct production engines per liter in the world. Honda is also up there with their F20C engine and K20Z3, but those are smaller in displacement.

    Note: you can HURT performance of the intake port of a head by porting it out wrong. Diffusion angles, flow areas, valve angles, surface roughness etc... all go into the technology

    Wow, thanks for the answers regarding this. Honda really deserves some respect for that s2000 and nsx engine and the price points they worked within. Ok the nsx was pricey but it was pretty special for its day.

    Breathe moderate amounts of air - EXTREMELY quickly. This is what makes an engine special.

    Easier to say than do, but this is the "key"

    If I could quote DBFIU - he is 10000% right. He points out the issues with doing the above ^ (4 posts or so)

    It's easy to do higher specific output with smaller motors, look at motorcycles.

    The F20C is nowhere near as impressive as the 458 motor or F430 motor as the F20C dyno's in the 195 whp range.

    Really, Porsche is making the best naturally aspirated high revving motors right now. The GT3 RS 4.0 is making over 100 wheel per liter, insane.

    still the honda came out in 1999, thats when the f355 was out and 996 gt3

    and the honda is a 20k car...so very impressive imo

    Look at the torque per liter numbers.

    It takes special coatings, a light valve-train and light internals, and a flat-plane crank with a special firing order to reduce rotating mass. Ferrari also uses pumps to maintain crankcase vacuum and for the oiling system to reduce frictional losses there. I believe I read they made 7% more power on a motor from the crankcase pumps vs without them.

    That is the reason they sound so badass as well.

    You can make some pretty high rev stuff out of "lesser" motors as well. Look the 11,000RPM 4G63s, RB26s, 2JZs, 10,000RPM NASCAR pushrod V8s, etc.

    Nobody revs higher than Ferrari with production V8's though.

    They can hit over 9000.

    Not quite so simple, you need torque at those revs to see the math do its thing.
