.......but thats silly as you could say having to use SUL fuel and not std cheaper unleaded is a compromise
Indeed, its very silly to say you can build an engine without compromise, hence I dont know why you said that?
its horses for courses you build the engine in a way you want it to perform.....
Not just how it performs either, many other factors:
Formula 1 engine:
Compomised between
Needing to make good power
Reliability of having to last a couple of hours
Needing to be fuel effecient to minimise the weight of the vehicle during the race and/or number of pitstops
Drag engine:
Needs to make good power
Has to last the full 6 seconds
Has to have a cam choice that allows good torque low down to hook up with, and also has good power at the top end to keep pulling
Toyota Aygo standard car engine:
Needs to make enough power for sprightly performance
Has to be reliable for 100,000 miles+
Needs to be economically viable for mass production
There is not one single engine on the whole planet I can think of that isnt built around multiple compromises, can you name one Phil?
If not why are you saying engines dont have to be compromised if every single one on the planet is?
And if you concede that every engine is compromised, then why is a 2 psi cap on boost for 1000rpm a bad compromise but all the other things mentioned are not bad compromises, you are making NO sense at all.
