Well, u would want the turbo to spool as fast as it can to achieve the boost u want. So there is no lag, if u don't believe me then, do the research, and then answer me back. It may not seem right, but u would need to deal with backpressure in N/A trim. For turbo, flow efficiency is the right point. Why do you think a 2.5" to 3" piping for a turbo tC (2.4) is a good idea? Because u need to let the turbo move the exhaust gasses faster to help spool time, also N/A needs thermal capacity in the piping to retain exhaust velocity, that's why backpressure is still needed. Go turbo... no need for too much backpressure since thermal capacity is there with the gases and temps from the turbo itself.
