Hey Criple rooster and everyone else,
Since a have a car with a very boxy rear end, most fuel savings will be had by improving aerodynamics. Adding a partial boat tail (and in doing so some cargo volume) seems very apealing to me. At cruise without mods at 100kph my intake air pressure is about 45% of atmosphere, thus if i improve aerodynamics just a bit i could run just 2 cylinders at 80 % atm. This would net me some fuel savings again (maybe 5 % - 10 %?) by reducing pumping losses.
What do you think?
Head gasket problems, fuel trim going rich, catalytic converter overheating?
