rev limiter question

[jordan 572]

i have watched youtube videos of a lot of cars doing burnouts and when they hit the rev limiter why does the rpm go down then up till it hits redline then backdown? i know this is what it is suppose to do but why dont doesnt the computer just stop the rpm at red line and hold it there.

The rev limiter accually cuts the ignition - at least it does on my bike.

A good driver doesn't hit the limiter because:
a) makes you slower
b) no torque up there anyway...

Nothing in the car will cut the ign, not even the onstar theft it slows it to idle but not off.

The limiter will just keep you from going over.

There are "hard" limiters and "soft" limiters that use various methods of control. Basically, don't ride the limiter. It is there as a protective device, not to support incorrect driving. Peak power on the LS3/L99 is at 5,000 so you will go slower banging the limiter. This is not like a step limiter on a drag car.
