...achieved? with a well tuned sfi injection system & a large roots style blower like an eaton m90 (gm 3.8 s/c's) as well as tall gear ratios, pumping a lot of boost down low & through the powerband (because everyone knows rotaries cant pull enough air to run half assed efficiently at low rpms), would it be possible to get 30mpg with one of these at 55-70 if the rear end gear ratio was high enough?
 
I'd say 30mpg is a bit high, but a reasonable 25-28, but also depends a fair amount on the weight of the car that it's in.
