I think this is the silliest argument against larger blowers. I made 685rwhp/605rwtq on pump 91 octane with a 3.4L Whipple pullied with a 3.5"/6.55" lower. (It was 17psi at 3400ft elevation, sea level would have been 20-21psi) It never felt lazy and trapped 134mph at 3400ft elevation. With my big bore motor its showing 15psi now on the same pulley combo.
It would be way better on E85, but the big blowers aren't lazy down low!
If you don't have easy access to E85 it will be fine on lower boost.
This is interesting to me because I know I would never use anything but 91 octane pump gas. I want to be able to drive cross country without thinking about it.
