Just curious to see how that affects gas mileage and of course performance...I have an 07 SI.

MPG will take a hit, but it sorta depends on how its driven. One kid I know has a turbo 8th and was complaining about only getting in the teens, and then proceeded to tell me how he was doing 100+mph on the highway, so that wasn't helping.

As for performance, mid to high 200's is pretty standard for the Greddy kit. There some guys with lots of tuning that have broken 300.

MPG shouldn't take a hit unless you have a crappy tune or are constantly on the pedal.

well u can get more power gains etc with a turbo setup rather than a supercharger...
like turbo is for serious power that can be increased over time effort or whatever u want really as in power gains... supercharger ,, eh u can do pulley, port polish, and or rebuild the whole charger .. but mostly i think supercharger is for just a gain ... not serious power as turbo can put out... but idk your choice as well as how much power u want outta the vehicle...
