i know this is a real stupid question :oops:

is there a kind of feul ratio with a diesel?
or the most efficient EGT?

I just bought a eco diesel -it got a NA pump but it got a turbo-
it feels like the car is a little little bit more faster when the turbo 'kicks' in.
Maybe its just in my head... :lol:

probably the main reason that the vehicle is faster when turbo is spooled, is because of reduced back pressure and more air feeding the motor. you would definitely see a big power increase if you increased the fueling, but more smoke when not boosting

0 egt would be nice... motor would be 100% thermally efficient

i think natural gas has the most potential for 0 egt

The simple fact is that at full fuel the fuel will burn more completely with the added air in there.

More power with the same feul...
is this a (kind of) air feul ratio or not?

Yes, because more of that fuel is being allowed to be burned due to the additional air in the cylinders
