There are two kinds of top speed. Aerodynamic induced and RPM induced. If your car doesn't have the wheaties to push the air out of the way at a 6,000 rpm redline in top gear, you're simply not going to hit that rpm. Therefore, your speed is limited by aerodynamic drag. If you add power and are able to hit the target RPM, you're going to have a higher top speed that will become RPM limited. In this scenario you run out of gear, not motor.
The non-SRT cars would probably be aerodynamically limited if the artificial limiter wasn't there.
There's not much RPM left after the speed limiter kicks in so it'd probably be rpm limited.
