Rev limiter Options

[jdogg]

How good is the stock rotor with the rev limiter in it? Is it reliable, does do what it is supposed when it is supposed to consistently?
I am currently running a non-rev limited rotor, but found myself wishing for some sort of limiter at the last autocross as the valves were floating! (IMG:style_emoticons/default/huh.gif)

There are positives and negatives about the rev limiter rotors. Rev limiting rotors work by cutting the spark, but the fuel is still being pumped into the engine so when spark comes back at a lower RPM there can be large bangs from the build up. Another point is that most over revs occur on down shifts where the wrong gear is selected in the heat of the moment so they won't help at all in that case. Many racers and hard core auto-x drivers don't use them instead using a shift light to help with up shifts and getting lots of practice to help with the down shifts. But if you are starting out and one will make you feel more comfortable then it is a good idea to use one. Good luck.
