The usual route is go turbo or for cars already turbo'd , go with a bigger turbo. I think considering we are still using the factory supercharger and nobody has done anythin to the gearing,transmission, upgraded fuel delivery, or done any major engine work we are doing pretty good. Unfortanetley I feel with the mods currently available high 11's are as good as its going to get without nitrous. I think we will be limited by the factory supercharger and intake plumbing either way .
