ok non me ero accorto ma hanno cambiato il regolamento nel 2022 XD
e) For a new engine the initial rev limit will be either:
a) The lower of:
i) The RPM after the peak power at which the engine
produces 90% of the peak power figure, + 3%
ii) The RPM of the peak power + 700 rpm
OR
b) The manufacturer may choose to continue with the current
RPM by balancing (if the new engine maintains the same
number of cylinders).

f) To be a considered as a “new engine” all of the following
requirements must be met:
g) A new EU/ECE type approval with an update to the engine type
number (if no valid EU/ECE type approval then USA or ASIA).
h) Changes to the following parts (however if any of the following
components can be considered as a “Product Update” then they
will not be considered in declaring a “new engine”):
a) Changes to one of:
i) bore x stroke (at minimum 1 mm bore)
ii) layout change (e.g. “v” angle or cylinder plane)
iii) relocate main shafts, countershaft, or transmission gears/
gearbox layout (relative position of the shaft must be
changed requiring a new casting)
iv) Valvetrain type change or valve actuation type change
b) Or changes to three of:
i) in/ex valve change (shape or material type e.g. steel to ti)
ii) conrod change (weight 4% or material or length 2mm)
iii) abolishment of balancer (for homologated model)
iv) introduction of seamless transmission or a new kind
of actuation system
v) included valve angle change (need value)
vi) piston (weight by 4% or compression height by 1mm)
vii) crankshaft inertia change 8%
viii) Throttle body (split or bore or main dimensions)
ix) Airbox layout, air funnels and variable
trumpets mechanism.
