Opti rotor RPM failure ?
I am curious at what RPM they seem most common to fail at.I am running a LE1 emission cam which I believe should top out at 6200-6400 rpm.It will have the Delteq setup on it , and wondering if it would be smart to make a rotor replacement or leave in there.The Opti is a brand new AC Delco unit for 95 and up.
It should last.

I believe the 6300+ range is when you can start to get some choppyness/cutting out of the ignition.
My opti failed when the seal for the opti drive failed, allowing oil to get in and eventually all over the optical eye and rotor. I would have surging at low rpms.

My rotor came apart @ 4500 or so. But that is @ 125,000 with alot of 6000rpm runs before hand. I think age has some to do with it and you should be fine with the new one in there.

Mine failed around 5,000 RPM and it was an opti that was about 10k miles old. Though I do distinctly remember the morning... the air was dry and about 35 degrees... power came on hard and the RPMs drove up to 5k pretty fast... then BAM! the motor was sitting on 50 rpm.
