FWIW, i will not add any kind of forced induction to my FRS/BRZ. |
a centrifugal compressor by definition is not liner. some people feel it and/or care, while others dont mind. we're all nitpicking here. so yeah it isnt that big a deal, but to some it may be, so we cant just sweep it under the rug. statements like "modern turbos have no lag" are just as dumb as "all turbos are laggy". the truth is somewhere in between and very personal to the driver's taste... the perfect example is the 335i vs 330i. the 335i is nowhere near "laggy" or lacking in response, yet the 330i is still more responsive albeit way slower.
my opinion is that for low boost a roots SC is the best option, then rotrex, then turbo. that's me. i like responsiveness
