2014-2020 Formula One 1.6l V6 turbo engine formula

All that has to do with the power train, gearbox, clutch, fuels and lubricants, etc. Generally the mechanical side of Formula One.

What does it mean that the cooler is indirect (or direct?)

Indirect means a water intercooler.

I thought Ferrari would have made the same system variable length.


Their V10 system was amazing even though turbo engines need longer pipes.

Engine sound quality on TV:

I asked FOM on improving sound and this was their reply:

Please kindly note that the sound equipment trackside is handled by each circuit - we believe they do their best to ensure visitors have the best possible experience during F1 races.

I remain at your disposal should you have any other question.

...because it is not like there are 22 microphones track-in that provide the sound that people actually complain about...

our world changed when Porsche turbo'ed the 917, producing the first road circuit-raceable turbo (ovals-only till this)
iirc due to their innovation - the recirc BOV - keeping up turbo rpm
TC Same thoughts. As a student I had an interesting discussion with a Porsche engineer about 935, and the same subject. Unfortunately they couldn't fit all the required plumbing in the engine bay of a 911 body.
If you don't want turbo lag, then don't let it's rpm reduce. I have a feeling that you and I, are considering, different types of waste-gates and BOV's, and a different layout. Better not give away the secret :wink:

And how would you do that without also NOT generating anymore electric energy?
Exactly! You would think that they all had spare electrical energy to send to MGU-K.

This is quite interesting idea. The penalization in the worst case is to start from end of the field (IIRC) so if some manufacturer decide to ditch reliability and go for pure power can this be an solution? If some manufacturer make a PU which last only for 2-3 race weekends it could be interesting. There will be few more penalizations but not so much...

According to Rob White, they dont use those sliding trumpets that go up and down which they used in F1 in the past. They're too long with a long stroke and take too much place. He said some road cars that use these, have a rotating device that is a compromise for gaz passage. What device does he mean?
This?:
Honda's trumpets look a bit like these IMO http://www.autozine.org/technical_schoo ... udi_V8.jpg

What is the trumpet length dependent on?

RPM, you want longer intake runners at low RPM, and shorter at high RPM.
It could also be dependent on load.

No that is not what I meant. What is the criteria in deciding the length required for low rpm and high rpm?

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.

BTW this effect is more useful on the other end of the engine to help get the gases out of the cylinder.
The higher pressure of the exhaust gases lead to a much higher effect.

Also, this is essential in tuning a two-stroke.

They could use last years loop hole and take a new PU in every session to build up a buffer of units for the rest of the year, thereby minimizing their penalty affected races.
