"Was I supposed to lose" YES YOU WERE
You would typically lose unless they had their black 500 hp key in the ignition.
Here is an example of a modified F10 M5 with a stage 2 tune and exhaust mods that pulls just one car from a third gear roll race.
For the past several years I have raced and watched a good number of stock Hellcats at the drag strip and they always have very high trap speeds since they have a huge amount of hp. I typically have trap speeds of 118-122 mph but on occasion could be up or down 2 mph. I had a stock 550M and it had trap speeds typically between 109-112 mph.
SUMMARY: If you are stock and a Hellcat is using their red key, unfortunately, you will lose.
