Really depends on the supercharger you buy. Expect to spend 2-3k in hardware. Another 2k on installation and getting it setup correctly.

There’s a company in Australia that sells and electric turbo that actually works, it’s 2500 bucks. No belt drive or exhaust mods needed. Easy to install, about 10 lbs boost.  It comes with a 48V control module. It charges off your alternator and hooks up with your ecm so its controlled by your throttle position. It can provide about 2 mins of constant uninterrupted boost when the accelerator pedal is pushed more than set threshold which is usually about 1/2 pedal or more. Cleetus did a video on it. Then he hooked up two of them. LOL

@Thumpy, for a 2019 I don't think there are even options out unless you got a custom fab. (S2k prices perhaps if new for the 2018+ years) That electrical turbo looks interesting though. Plus you would need to find a tune. @Jay Martinez, there be a reason you are looking to void the warranty? I mean I get it and all but just curious here. If you just want to be faster, a good set of wheels, tires and suspension would shave a lot off your lap time..

I'm not aware of any off the shelf supercharger kits for the 2019 model as of yet. A custom fab one would cost crazy money.
