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)

Your reasoning is exactly how I 'use' my rev limiter. In autocross, I often (nearly every event) find myself at the top end of 2nd gear, but in a place where it doesn't make sense to go to 3rd and then immediately back to 2nd. And like you say, there is too much going on (and too much adrenaline) to try and limit your rpm's yourself. In these cases, I just ride the rev limiter until it's time to hit the brakes. Adding a shift light will not help. I have no problem knowing when to shift, I am simply choosing not to shift.

I've never had a problem with backfires or 'bangs' from the fuel build-up. Any rev limiting system that you will add to your ignition system will limit the revs by cutting the spark. To do it any other way would require an entire engine management system (one that can control timing and/or fuel flow).

A rev limiting system is well worth the money - even if it costs a few hundred bucks. But the $20 solution works just fine if that meets your needs. It will work fine with the Pertronix system assuming you already have the pertronix. If you are planning to buy a Pertronix and a rev limiting rotor, then I would suggest looking into an ignition system that will provide the rev limiting electronically (MSD, Crane Cams). I cannot recommend a system, but others on this list can.
