single turbo,TT, or supercharged

tcmaboy...yes, you should build according to intended use, but there are an endless number of compressor housings, turbine housings and wheels out there so you can find a turbo to do what ever you want. You say "if you want a drag queen or dyno car, a big turbo's fine"...sure. But then you say that for the street or track, a S/C is better. Why? Just get a smaller, quicker spooling turbo. It may even be possible to have the best of both worlds, low/no lag and huge power, if you research and design properly.
