What can be done to make the engine louder?

[langwadt]

Ditch the fuel flow limit and kg limit and let them have specific qualifying engines with no restrictions, no rev limit etc.

with no flow limit they would probably run lower rpms, to get them to run higher rpms they would have to
increase the rpms required for full fuel flow, but they can't just do that with years of development invested
and frozen engines designed for 10krpm

Ban the turbo but allow the electrical compressor side, unlimited kinetic recovery, lift revs to 20k.

[komninosm]

Well if the issue is essentially a lack of revs due to the maximum fuel flow, drop two cylinders to increase the available fuel flow to mix with the air flow at higher revs.

This is all ferrari's fault

Not really no, it's simply technology's fault. We have advanced substantially in our ability to design efficient engines, the result is that very little energy is wasted as sound now. We simply can't have modern formula 1, and noise at the same time I'm afraid.

And I for one don't want any more noise.
In F1 or in real life.

But hey! At least we can here slipping tyres and a beautiful turbo sound LOL

Yeah, I'm loving the slipping tires sounds.
I find the turbo a bit "futury", but i like that too.

That doesnt actually sound much different to what we have now..you can still hear the announcers in the background.

All that needs to change is the sound engineer for the tv broadcasts.

Guys, 'come on.
I am an audio engineer and this is really simple.

Have you ever watched Thursday practice at Monaco? Sounds fabulous. You can hear a car wind through the streets all by itself, with hundreds of reflections off the buildings.

Right now there are no boundary effects happening. Every time you've heard a car, either at a race or from video, you are hearing reflected sound. The exhaust is reflected by a boundary like the tarmac. The 2014 engines have the exhaust pipe pointing straight out into what can be called "free space". Want the cars louder? Point the exhaust down.

I'm sure they are looking into this right now. Probably some clever engineer will couple that downward exhaust position to some point where there could be an aerodynamic advantage?

Cheers,
Radley

[lebesset]

there is an even simpler solution .... get bernie and monte to shut up moaning .... maybe the engines won't BE louder but they will SEEM to be louder

[sennaf1god.94]

Scrap fuel flow sensors and implement a mandatory fuel cell of 107 littres.

Without this engines will never reach the max. rpm's as written in the rules (15.000rpm)...

Now engines can't even get 12.000rpm without getting a call by the FIA reminding you Mercedes are the only ones allowed to break the 100kg/h rule...and you don't in the name of "efficiency"...

No, they would rev as low as the regulations allow them. Higher rpm = higher frictional loss. RPM =/= loudness anyway.

You can gear the cars to do 15000 rpm, but you'd lose out on performance. You could further limit the fuel flow to reach 15000 rpm, (eg, full flow from 10500 raised to 12500) but the cars would be slower.

As for the rest, Nice conspiracy theory. But its irrelevant to this discussion. Save it for the illuminati discussion boards.

Source please? Where we could find that. We are on technical forum so elaborate and support your "theory".

You can switch Mercedes for any other brand in the sentence, as long as you place on the MaFIA the good faith of the ruling, you get a F1 where they can actively control the results of each GP and consequently the fate of the championship.

Instead of making mandatory a physical fuel restrictor, they preferred a device that only measures the flow but that can't actually control it. Therefore you have the RB gate...

The 107littre fuel cell is just efficient and doesn't need any active device onboard to make teams comply with rules. All this complicated systems only obey the need of controlling the results.

Plain and simple.

You can't get it.

Rules dictate a limit of 15.000 rpm max.
Engine manufacturers can't get past 12.000rpm on the dyno or 11.000rpm on the racetrack due to starvation forced by the 100kg/h flow limit.

Allowing a bigger boost from turbos alone won't have any impact on rpms, allowing the engine to get more fuel will.

Both, breath and eat, are needed if you want a noisier engine.

The engines can, but they've been designed not to. Because there's no advantage in racing to having a very wide power band. Certainly not with 8 gears. The fuel flow only reaches peak ( 100kg/s) at 10500 RPM, but because frictional and pumping losses increase as engine rev's increase, they don't.

If the fuel flow reached peak at 8000RPM, then the engines would rev to 9500RPM during the race instead. There's no advantage to rev high, when you can just increase cylinder MEP (like in turbo cars).

Bullshit. Watch the onboards from Bahrain, Force India went to mid 13k rpm on their qualy laps.

WTF???

Engines can cope with revs up to +18.000rpm, if allowed a higher fuel flow, without any significant frictional loss. They were designed with the 15.000rpm in mind!!!

More turbo boost would be needed for a better whooshing sound anyway
