Default Whats The Rev. Limiter & Can It Be Tuned Out?

Curious on what the rev. limiter is supposed to be. I'm guessing it's around 6,000 rpm cuz thats about where it's cutting out. I had recently disconnected the battery and now this limiter seem to be in affect. Before I had disconnected the battery I don't ever remember there being a rev. limiter on my car. I was curious and wondering if there's any way that I can tune this out by myself without taking it to a shop and getting it tuned out. Thanks!!!

Why would you want to tune it out, it can save your engine if you lapse in judgement or shifting ability (barring a forced mechanical over revving)?

yeah, let it go. these motors make their best power around 5700 rpms anyway, youll lose power after that.

The rev limiter will only ensure that there wont be any fuel in the cylinders when the engine is mechanically overrevved. Make sure it doesnt happen, if it does you'll hope that you only bent a couple pushrods.

-edit- To answer the question. The rev limiter ceases the flow of fuel into the engine at a specified RPM in order to prohibit it from revving any higher than said RPM. It is a safety feature and should not be eliminated. The factory setting is 6200 RPM. The limiter can be raised to allow for the top end gains seen from mods such as a bigger cam etc, although some people raise it on stock / lightly modded cars. Some people set it up to and above seven grand but that's my personal limit. When I do raise it (I havent yet) I dont think I'll even go that far.

I can read it now..... "I removed the stock rev limiter, revved to 10k and put a rod through the block.... I dont get what happened"

I was telling him, not you. Just trying to communticate the message that mechanical overrev is a very bad and potentially very expensive couple of seconds. Never had the experience myself thankfully.

Rev limiter is not going to do **** for you on a missed shift. It prevents over-revving from your foot being on the gas too long but not a mechanical over-rev.
