I really can't say what's faster than a NA car from actual experience, because it seems like NOBODY ever challenges me anymore since I've swapped hoods.
I can tell you about 3 cars I backed down though.
A newer Mustang GT, Porsche 930, and a S2000. In all 3 circumstances I noticed their owners were driving aggressivly thru traffic for some time before I finally was able to pull up beside them. After checking my car out, suddenly they became the most docile, law abiding citizens on the road.lol
"Intimidation" is one of the best performance mods you can make.
As far as I know, nobody ever gets a "moving" violation for that.
