I would set it at 9,000 RPM if a later GT3 RS. (meaning, what are you driving?)

My 81SC has a 6,400 RPM red line. I set mine at 6,500 with a pill on my older MSD 6AL. You probably have a dial. Others will have better data once they know which car.

Hi,

Thanks for that bit of info; I failed to see that in your original post,..

Set the rev limiter for 6500 RPM as that's the safe limit for cast pistons. You are well past the power peaks at that RPM, anyway.
