2014-2020 Formula One 1.6l V6 turbo engine formula

The trumpet length is depending on the rpm where you want to set the resonance frequency of the inlet tract.
This gives you a slight charging effect.
You can influence the power and torque curves with that.

So basically you chose the rpm where you want the highest effect and set the length for it.
Here you have to take into account the rpm, speed of sound, valve timing.

They have gotten their explanation about intake pulse tuning slightly wrong. Here is a better description from Heywoods "Internal Combustion Engine Fundamentals":

"As the piston moves downward during the intake stroke, a reduced pressure occurs at the inlet valve relative to the pressure at the open end of the inlet pipe. A rarefaction wave travels down the intake pipe to the open end and is reflected as a compression wave. A positive tuning effect occurs when the compression wave arrives at the inlet valve as the valve is closing."

This is basically the same, but opposite from what is happening during exhaust pulse tuning. When the exhaust valve is opening a compression wave is formed, which travels to the collector in the exhaust manifold and is reflected as a rarefaction wave and travels back the exhaust valve again, preferably arriving when the exhaust valve is about to close.

First fire up of the Haas-Ferrari VF16, shared by Romain Grosjean.

But why does the Ferrari engine sound like the Mercedes in 2014??? New firing order?

Sounds like the Mercedes. Nice!!!

tuned lehgth inlet systems appeared on motorcycles decades before their 'invention' by Mercedes-Benz as attributed in the Autozine reference
in 1938 ? Norton race motorcycle was bought by the UK National Physical Laboratory to investigate 'free supercharging'

tuned length won everything in car WDC when that went to F2 rules in 1952 & 53 (Ascari in the Lampredi-designed 4 cyl Ferrari)

basically, tuned length in cars had been stifled by the dominance of supercharging from the early 20s to 1951
many N/A 1 inlet tract/cylinder engines eg fuel injected Offenhauser and 30s UK Freddie Dixon disciples seem short of the tuned length
the tuned length of course being all about enabling and using further extended valve timing

Mercedes-Benz did invent the continuously variable length system for the 1955 sportscar (WEC equivalent) - it was never raced ?

so Renault with nearly completely new PU in Canada?

So much slagging of these engines from the onset, not noisy enough, not enough cylinders, they're too restrictive... Today we saw these engines top the fastest ever lap around Albert Park with Lewis Hamilton's 50th pole.

Schumacher's 2004 lap of 1:24.125 was toppled by Hamilton with a 1:23.837 not bad when you consider they're doing it with 50% less fuel.

Vettel did 1:23.5 in 2011.

Missed that, I stand corrected. Give it another year. Don't miss the less fuel part... damn new qualifying format.

2011 had DRS on demand during qualifying laps.

2016 has super soft tires.

Different things are different

Can't really make any direct comparison for 2004//2011//2016

[Tauri_J]

2011 had DRS on demand during qualifying laps.

2016 has super soft tires.

and higher tyre pressures

Didn't cars qualify with race fuel in 2004?

Qualifying was slower than 1.24.1. It was a race lap with very little fuel (but somewhat used tires).
