Lots of drift videos posted show guys just holding their cars wide open and allowing the rev limiter to help control the overall rpm's of the engine. I thing that the rev limited actually does not limit using the fuel pump control and instead only fires every other stroke of the engine rather than every stroke.
From Wikipedia , "Limiters prevent damage to an engine by interrupting the power that is distributed to the spark plugs, this prevents the engine from operating above a pre-determined RPM level known as the redline. The RPM level that results with the spark being arrested can be a constant level, or, with the proper ignition control modules, variable. Variable rate ignition modules can be adjusted quickly and easily to achieve the appropriate RPM limit for different situations, such as street racing, drag racing, road course racing, highway driving, and lawn turfing."
