Here's an equal comparison: Take $5000, add it to horsepower on a Miata, Hellcat loses every time.
The host of Fast n Loud was at an NHRA Top Fuel event this past weekend where they ran a '70 Hemi Cuda vs. Hellcat.
Hellcat killed the Hemi, like 12 car lengths type death, but only ran a 12.1. So, I'm thinkning your average Joe will probably be getting these to run 12.4-11.90 in a "test n tune" type event.
