A supercharger (at least, Cetrifugal) will never produce the boost of low end grunt that a well sized, efficient turbocharger will... Roots blowers are better, but are still restricted to the engine speed for its maximum output... This is why people slate the Rotrex setups and one of the main reasons I wouldn't have one... They have all the disadvantages of an NA engine and all the disadvantages of a boosted engine... Unless you get a seriously big charger and allow that midrange torque to come up, it's just like an extended NA engine... Everyone goes on about it being linear, but at the end of the day - you look at what manufacturers are striving towards these days - and that's the graph that I posted above, torque coming in early, then the power going on to the redline... Not the torque rising at the same rate as the power all the way up the RPMs...
Meh, I don't care at all... But at the end of the day, a well set up, efficient turbo setup without someone getting distracted by shiny bits and sticking to the problem in hand and taking the time and effort to choose things properly, not just guestimate - it'll ALWAYS be better than an NA engine - it can't not be, forcing air down the inlet will always be a more efficient way of doing things...
