You have to also remember that in 'real world' driving, is not always good to have a huge turbo as they'll be laggy and before its fully boosted up and your getting its full potential you'll be at the next bend in the road and having to back off, and that n/a engined little pug 206 gti 180 (good example of a light nippy n/a engined car) will be well away leaving you behind.
