Why does the F355 sound so much more F1ish than the 360 or say 430?

Hand down the F360CS has the closest F1 sounding exhaust note of any Ferrari, except maybe an Enzo. I have not yet heard an F430 Scuderia at full throttle, so there's that. The 355 engine comes close especially goth's with the Capristo (now removed).

As for the Maserati engine, well, let's say it was a Ferrari/Maserati/Fiat partnership that created it. It was originally installed in all the late-model Maseratis - GT, Quatroporte and now the Grand Turismo. It was always planned to be the next generation V-8 for Ferrari. To call it a Maserati engine is totally bogus. Maserati was lucky they had the benefit of the Fiat/Ferrari partnership to even get the motor. Another beneficiary is Alfa Romeo who gets to use the engine in their new 8CS, or whatever that overpriced POS gets named when it hits our shores. What is interesting is that Maserati is keeping the engine rather tame at around 400 Hp (430 Hp in the Grand Turismo), while Ferrari and Alfa have pushed it to the limit near or over 500 Hp (485 in the Alfa and over 500 in the F430 Stradale).

 

What about the bore and stroke of the cylinders? Displacement has gone up from 355 to 360 to 430 and each time displacement went up, the sound seems to become deeper. I look at it like a pipe organ in that regard, the longer and wider the pipe the deeper the note and they all can be music to the ears. Just my thought of something that may have contributed to the change in pitch.

Dave we both were typing the same response and posted within seconds of each other.... and to make sure he heard us you posted it a 3rd time....

 

thanks didnt know that...i agree with you.

 

My recollection from somewhere is that the firing order changed from the 355 to the 360 in addition to the other stuff posted above which also makes a difference.

Listen to these.... !!!

Don't forget the 355 engine is a predecessor to the 360; the 430 motor is the joint Maser/Ferrari/Alfa engine. Certainly the intake and exhaust systems are different between the 355 and 360 and so are the resonators. That's where I think the sound difference comes from. Remember these sounds are "tuned". If you spend enough time at it, you could get either car to sound exactly like an F1 car at least until you ran out of rpm's. Engine note is a complete package comprising so many elements, not just the exhaust system.

 

my friend used to have a 355 with tubi and cat delete; sounded amazing, and very F1, very loud and high pitched.....

However, he now sports a 360CS with hyperflow cats... and that setup sounds pretty dam insane (especially if you disconnect the bypass valves)... when we roll together, I can't hear my car (and I have test pipes and X-OST)

I was rather dissappointed with the sound of the F430......and from what I heard, you can't mess around with the catalyics.... and I was especially disspointed with the sound of the F430 challenge cars .....

 

aha gotcha

 

Displacement difference between 355 and 360 is 3,496cc's vs 3,586cc's so yes you're correct only about 100cc's difference, not much. But the 430 displacement is 4,308cc's which is 812cc's more than the 355 so the 430cc's is almost 1/4 greater than 355.

I have to agree. My 355 had the level III capritisto and my new to me CS has hyperflows. The sound from the CS is amazing and to me sounds even more F1ish. The hyperflows also added an additional 25hp at the rear wheels (dyno proven) - win-win.

 

Kreissieg Makes some great sounding exhausts as well!

Compare for yourselves:

And just for good measure a Countach! (the best of them all!)

Good Noise - very nice

 

They sound great at higher RPM.............. though at idle they lack a bit IMO...

 

+1

 

Rookie,

 

Just yank out the motor and put in a real F1 engine. I'm not sure if I want the 10 cylinder @ 18,000 rpm or the ol' V-8 @ 20,000 rpm...listen to the Cosworth clip at the end when the rpm's drop to 9000, the engine sounds as if its at idle compared to 20,000 rpm.

http://www.youtube.com/watch?v=miRDt3BTmmY&feature=related v-8 @ 20,000 rpm

 

Quick video of my car today....it was gorgeous here in Hotlanta!

Great videos !!!

 

I know this is a taste thing - but I almost find listening to the unloaded engines like the countach and the LP 640 annoying rev'd up in neutral compared to under load. In neutral, the Horsepower required to spin the engine is less than 10% of that under load. The flow and the heat through the engine is what, gives you that throaty (not winey) sound. The F355 and the F430 tapes with the car accelerating away were under load. Awesuuum!

 

Sorry - for those without a Thermodynamic background, the heat addition from adding increasing amounts of fuel to increasing amounts of air is what creates increasing amounts of horsepower. When you crack the throttle in neutral and the engine easily races to 8000 RPM you are only using a small amount of fuel and air to do it. Under load, the air valve is full open for maximum air supply and the fuel is being added at the maximum rate to get the most possible heat addition which equals horsepower. Flow and Sonic velocities in the exhaust change with the increased temperature of the exhust gasses and hence the apparent "note" change under load.
