What he said. At most surface street legal speeds on the street, the car will be barely quicker than a stock '18 GT A10 PP1, because, traction. Granted, the '18 GT PP1 A10 accelerates significantly quicker than the Gen 2 Coyote powered cars with the M6 or A6 trans. So for your car, the difference at lower speeds (i.e., 30-60 mph) will be noticeable. Below 30 mph, both cars are spinning anyway, so the difference will be negligible.
The difference is the supercharged car can accelerate much harder at highway speeds, as you get near the traction limits of the tires at higher speeds. Stop light to stop light (i.e, 0-40 mph), the difference will likely be negligible. So, I guess the question is at what speed are you curious about? Low speeds? Negligible (due to traction limits). High speeds? A supercharged car will likely accelerate at 80 mph about as hard as your stock car accelerates at 50 mph, give or take, depending on boost, rwhp, etc. At 50 mph, the supercharged GT will probably accelerate about as hard as your stock car at 25-30 mph, both being traction limited at the respective speeds.
I've compiled a lot of data on acceleration for many different makes and models of performance cars. For comparison, the GT500 only ran 0-60 in 3.6 seconds vs. the '18 GT A10 PP1 which does it in 3.8 seconds (C&D), and that's with 1.6" wider rear tires (275s vs 315s). However, at highway speeds, the difference will be significant, proven by the fact that the GT500 does 60-100 mph in 3.4 seconds, vs. the A10 GT at 4.7 seconds. Anecdotal evidence of the low speed traction limited theory: One time I ran a modified Charger Hellcat on the street with my stock '18 GT PP1 A10 from 10-50 mph (brief, yes). We were dead even because we were both spinning most of the way (me through first gear and into 2nd). He was just spinning the entire time, so even though his car made something like 300 more hp than my stock GT, it was a tie for that brief stint (we both took off at the exact same time). We both have 275 width rear tires.
Let's compare the stock 2018 GT A10 PP1 numbers to the current GT500 numbers:
Per C&D, the '18 GT A10 PP1 did 60-80 mph in 2.0 seconds. The '20 GT500, per Motortrend's recent test, did 80-100 mph in 1.9 seconds. So, essentially, the GT500 at 80 mph pulls about like the '18 GT PP1 A10 at 60 mph. Mind you, the '18 GT PP1 A10 pulls very strong at 60 mph so the GT500 pulling that hard at 20 mph greater speed makes a big difference in overall acceleration (proven by the 132 mph trap speed of the GT500 vs. the 120 mph trap speed of the '18 GT). Make sense?
