negative effects on lowering rev limit? I'm gonna start auto crossing my car once in a while and since i'll probably be in the stock rev limit a little bit, i was wondering if there would be any benefit to lower it. I know my car stops pulling as hard around 5500rpms. So if I lowered it to that and hit it more..would there be a negative effect..as opposed to hitting the 6250 stock limiter the same way?
I guess my actual beenfit should be..how much damage does hittting the stock limiter cause(I know you could bend a pushrod or have valve float)..would lowering it eliminate that?

the rev limiter is there for a reason, no damage will result. Overrevving via mechanical or otherwise may damage your engine. why dont you get a shift light and program it?

it wont help, and it wont hurt either.
to be honest, upgrade the driver. if you dont make power over 5500, then shift there. dont give yourself another crutch to depend on...

I do shift there..at the drag strip...but auto crossing is different.
ummm ok, youre not gonna hurt anything by hitting the stock rev limiter once in a while.
instead off learning when to shift yourself depending on the situation, reprogram the PCM. whatever floats your boat. and it IS a crutch. if you can't learn to avoid the rev limiter through practice, then forcing the PCM to lower it for you so you dont have to worry about it IS a crutch.
But you seem to be taking this personally now, so do whatever. it wont hurt anything to lower it.

Alternating pulling fuel and or spark from cylinders isnt going to be nice to your motor either. Im sure it adds some sort of bad harmonics and vibrations yoru bearings could live without. But you wont damage anything due to engine speed for sure.
Leave the limiter where it is. Its not the limiter thats causing valve float, its mechanically overrevving it thats causing it. Just dont stick it in the wrong gear.

There's no sense in lowering it. There will be times when you will need to shift into 3rd right before a corner. But shifting up to third, then having to get on the brakes right after is slower than if you had just kept it in 2nd and just revved it a little higher. The rally guys call it over rev. Rally cars peak at 4500, but redline at 9k. Those extra revs are called overrev and they are used only in the situation described above- approaching a corner with the engine past peak power. Real road race cars know the track ahead of time and select their ratios so that this situation never arises. Rally and auto-x don't have that luxury and so they benefit from a bit of overrev.

If youre that serious, why not put in a set of 918 springs and raise the limit to 6800 on the stock cam. You can still claim stock heads and cam, yet youll be able to up the limiter a bit. Heck, you could even replace with LS6 springs and raise the limit to 6600.
