depends on how much power you plan to make.
A stock scat pack has 425-435hp to the wheels and way more torque.@MoneyMopar.
I'm going to Supercharge (SC) my '19 SXT next year with a RIPP kit. I've read many....many comments and articles about this very subject. I've gone back and forth about it with many on here. Here's what I know. You DO NOT have to upgrade anything. Not sure what you paid for yours, I bought mine brand new for $22k. It would take me another $20k in upgrades to get to the cost of a current year Scat Pack (SP). Add on a SC and a tune and it'll way be less than "Should have just got a Scat Pack" and potentially have the same RWHP with much cheaper insurance. Though, the SP will still have more RWTQ.
I've seen videos and conversed with others that have the SC on the V6. Many report they do not change a thing and have no issues... but it is a roll of the dice. Some had blown head gaskets not long after, torn up their xmsn or rear diff. I think it depends on how well it was taken care of before installing the SC, who installed it, and if you plan on actually racing it a lot after. Drag racing puts a lot of stress and load on the engine...any flaws get exposed quickly.
If you plan on racing it... I personally would upgrade the brakes, rear diff, and driveshaft/rear drive axles. You can find used Limited Slip Diffs (LSDs) for around $1200. Or go to a local junk yard and see if you can get one.
I have seen or spoken to someone with a SC V6 beat a SP from a dig (0-60) but loose from a roll (40mph up). The video above never shows from a dig and is the outcome I expect from a roll with an experienced drag racer. The SC V6 will slay "stock" R/Ts all day, every day. Many videos on youtube of this very thing. I just want mine faster as I feel there is much potential to be had with the bonus of gapping smug V8 owners.
And for those of you who want to argue about if the SC V6 RWHP can equal (or be greater than) the SP RWHP, there is actual dynos of the SC V6 having 425 RWHP with a well tuned RIPP kit. The stock SP is 475 "crank" HP, which is just around 400 RWHP. Here's a handy guestimator: Wheel Horsepower to Crankshaft Horsepower Guestimator (mk5cortinaestate.co.uk)
Watch this SC V6 beat both a SP and SRT8.

In all fairness, there are lots of other variables that go into play with any of these cars: tuned or not, changed out headers and exhaust, tires, etc. Once I start my build, I will post pics on here.
I can agree with everything you stated. The SP RWHP is just a guess, I have yet to see an actual dyno. Probably find one on YouTube. The SXT V6 is not designed for racing at all. But I'm going from a perspective of... I just want to make mine a fast sleeper when I need to be. I don't intend on drag racing at all. I like to make do with what I have while making it better if I can. I want that feeling of accomplishment of taking something meant to be a daily and making it an unexpected beast. V8s already come with the notion of badassery, not the V6.A stock scat pack has 425-435hp to the wheels and way more torque.....
