I bought my car with the mods in sig and I was just wondering if it's safe to rev it over the stock redline. I don't think there's a limiter since I saw the needle go near 7 once.

Where is the stock limiter and what is the part that holds it back from going higher?

THanks.

If you have a custom tune, it's entirely possible they changed the limiter. I had the limiter changed on my Trans Am when I upgraded the cam and springs.

I believe the stock rev limit on the LS6 is 6600 RPM. The LS7 has a limit of 7000 RPM.

I bumped mine to 6800rpm....I usually shift around the 6600 ~ 6700rpm area. Should be ok as long as you have proper valvetrain geometry and quality valvesprings.

I definitley won't make a habit out of revving it higher, but I just want to make sure it's ok to have it up close to 7 every once in a while. It's my DD so I don't really want any extra stress on the parts I don't need.

i changed mine to 6900 but set the raptor to 6600 to give me some safety!

With the AFR heads, the dual springs, and the cam it should make power all the into the upper 6000s. I would guess it would start to drop off around 6800 to 6900 RPMs. Best way to tell for sure is to run it on the dyno. A couple of pulls is pretty cheap. Once it is dynoed, you can see where the peak rwhp is at and set the limiter to that.

I take mine up to 7k sometimes when banging gears so im gonna say your's should be the same or very similar to mine, just take it on a dyno to make sure tho.
