Wouldn't that be an argument for running a smaller pulley on the bigger blower, though? To put it into its efficiency range quicker? You can run a 2.8" pulley on the Whipple 2.9 on pump gas. For the '11/'12 GT500, you can run up to 21psi of boost on pump gas. I'm sure running a 2.8" pulley would nearly eliminate any advantage the smaller TVS has. I still stand behind my statement that a 2.4" - 2.6" pulley on the Whipple 2.9 would destroy a TVS running the same size pulley. Only problem with the Whipple there, though, is that you'd have to convert to E85 or race gas full time with a pulley that small.
