i am not saying there are not times when twin/quad/whatever isnt good but single is clearly better. overhead alone is a lot. is filling your gas tank halfway twice at two different gas stations just as easy as filling it up once all the way? no. of course not. Clearly parasitic losses are significant here. Big win for the single. turbulance is a killer. A single greatly reduces the amount of energy that must be expended to make some boost, and decreases the heat and resistance on the compressor side. Would anyone even try to say that a twin setup has equal or less turbulance then a single? i hope not. gasses also flow best not in the center, but towards the edges of a tube. big win single. with twins, 1.5 liters has to spool two blades, two shafts, etc etc. with a single 3 liters has to spool one blade, one shaft, etc etc. even if the ammount of actual work was the same, single has a huge advantage in the overhead here. by the way, a single large turbo is much more efficiant. Anyone who would like to argue that making a certain CFM using twins takes less exhaust energy then singles, id love to hear an explaination. I will be surprised if anyone can come up with any explaination that even hints at sense that gives any advantage to the twins. discounting stuff like drivability etc. Is a single better theoretically? definitely. Would a single be better on a Z? probably. is a single practical? probably not. Is the greater effieciancy of a single going to suffer somewhat because of the convolutions associated with putting a single on a v6? almost definitely, to some degree.
