you get more low down power (which would be great for an auto) by using a supercharger... turbos requires you to be using the engine in high rpms to get boost therefore making you engine wear a lot faster than with a s/c'd engine
each to their own i spose, but, dont tell me... your doing this becuase you saw fast and the furious?
I can't believe there is still so much misinformation out there for the super vs turbo route. In my experience with turbos it is VERY easy to get a turbo to be making similar power to a supercharger at low revs, I'm talking under 2000rpm and still beat the hell out of it up top. It is all about having a good computer/tuner and a well matched turbo. With all the advances in turbo technology in the last 12 - 18 months there is no need for the argument that turbos don't make power until high in the rev range....
And also more wear....please!! I had a well built 1.3l swift GTI motor making 160hp at the front wheels for 130,000km's.
