Why would RPM increase with a higher fuel flow? With this kind of turbo tech, high RPM is not part of the power equation, air is pushed in the engine instead of pulled in, like in a NA ICE. Because of this to get the least internal resistance and the best and most complete burn of all the fuel available, you need the RPM as low as possible.MatsNorway wrote: ↑30 Aug 2019, 09:49If you also allow CoG to be lower, equal to the MGUH removed you claw back some cornering performance
If you allow them to run flat fuel flow from 0 rpm to Max rpm you claw back some efficiency. can you guess how much? i have no ideal.
And if you do that you would also get better sounding engines with turbo lag that could improve overtaking.
Why would they sound better at lower rpm? they would run a fatter fuel mix at times and the turbo will be taking out less of the engine sound as it has to be spun by the engine only.
Add minor tweaks to the engine formula such as free bore and stroke ratio and you could look at a ICE that is more efficient, cheaper, lighter and that sounds better and is more relevant for road car development.
I honestly do not understand why FIA do not go that route for the future. RPM will not improve these engines without increasing fuel flow as well.
Restricting the design of the engine (bore, stroke, capacity, angles, etc) is a huge cost saving. Just imagine how many tests they have to perform on different layouts only to get it wrong.
