I was referring to linear in a control method, aka when I push on the throttle, I have much greater control over the amount of force being applied to the wheels.@gregersonke
I think mine and @Nateness reply was with regards to your description of a Turbo being "linear". It is not, but I don't think you are using the right word to describe it "linear" isn't the correct term. Maybe you mean "gradual", based on your reply. Yes, turbo's tend to be more gradual then a supercharger in terms of power delivery.
230hp might be a little optimistic given these results on a ND miata.
[Supercharging] OpenFlash Electric Supercharger Dyno Tuning (it begins...) - MX-5 Miata Forum
Keep in mind that all of BBRs dyno results are in BHP, which is closer to crank hp. They do have a 190 bhp package for the Mazda 3, but that requires you to buy their header, intake system and tune. Its basically the same power you get from an OV tune combined with a SRI. The Miata makes around 10 hp more tuned than a Mazda 3 (seen from many tuners) since it has an upgraded stock exhaust cam. Typically, tuned Miata's make power till 6500-7000 rpms, whereas Mazda 3's stop making power around 6000 rpm because of the limiting exhaust cam.Don't mean to derail this thread but I have been seeing what BBR has been doing with the MX5 2.0 Skyactiv and it's impressive. I know that it has a higher compression ration and runs on Euro premium but the results look promising.
