Redline
I know the redline in the new GT's is 6000rpms, but is there any reason to go past this while racing or is it a bad idea? I havent done it yet, but I was reading about an intake for the 05-07 GT and it was talking about gaining 22hp at a 6100rpm peak. How could that be if the redline is 6000rpms? Thanks

RE: Redline
Most of us set the rev limiters up a bit (mine is at 6,800) to keep from hitting them under normal conditions.
6K is usually around my shift point. I don't think running it all the way up to 6,800 buys you much (if anything) unless you are modded enough (cams/heads) to have shifted your torque peak significantly.

RE: Redline
I *believe* the stock rev limiter is set at 6,250
My Brenspeed tune came with the rev limiter set at 6,800. So not a lot for a small block.
Again, you're not building any power after about 6K so that makes a good shift point. Moving the rev limiter up a bit just insures you don't hit the dreaded fuel cut off if you are just a little late with the shift.
I have not heard of anyone grenading their engine by over-reving it.

Oh ok thanks. But by over-reving it, do you mean past 6000 to say 6200, or past 6000 up to 6800? Like you said, I would always try and shift at 6000, but you know in the heat of the moment I might forget because I'm used to my 8200 rev limiter.

I mean past 6,800. I've had mine 6K+ multiple times with no problems.

RE: Redline
going past 6K won't kill it but to much can. Your valve springs are only good until so much rpms. Say you did hit 6600rpms, you could easily float a valve or break something else or it could be fine. I know some people with SC's or nitrous and gears will usually trap in the 1/4 mile track in 4th gear around 6K or 6200rpms, but i wouldn't try to do that much, accidents happen hear and there though.

RE: Redline
I think the stock setting for the rev limiter is 6200, I have hit it a on numerous occasions. It is a bitch because it just shuts you down, then the throttle by the wire waits for what seems an eternity (probably half a second) to turn the gas back on after you make the shift. The best thing is to make sure you shift at 6000 rpms to aviod the shut off. If you use a tuner to raise the limiter you are asking for trouble on a stock bottom end (premature engine failure) and the horsepower and torque drop off pretty quickly after 6 grand anyway. Put a set of 4.10's in an you will always be in the power band.
