A fast rc nitro car would be either the Traxxas 4tec 3.3, or the Schumacher Fusion.
Or if price isn't an issue, get a 1:8 scale IC circuit car. For example…

Brushless motors are a little different though. You could have what is believed to be the most powerful brushless motor, but if it's matched to the wrong batteries it will perform distinctly average.

Driving skill has a lot to do with it too, it's no good having a fast car if it isn't set up properly and you can't control it.
