comment Engine Size and Fuel Consumption
@draksia, For emmisions sake when operating in closed loop, the A/F ratio is very controlled. A narrowband O2 sensor tells the ECU if it is over or under stoichiometric mixing and it will adjust instantly. At 18:1 you likely to get lots of NOx emssions and it 12:1 you get lots of unburned gas and other pollutants (see here ).

There is also valve spring surge, at high rpms, but that is a different matter.

comment What is a modular clutch?
Thanks for the explanation. By not having a flex plate with an aftermarket clutch, does this give an advantage in reduced rotational inertia ?
