I have a 3120 rev limited to around 9500 rpm. If I'm milling big wood say 3 foot wide slabs, what will I really miss with the limited coil? Will my cut times be considerably slower then the 12k coil or unlimited? Is it a good thing to have it limited for my purposes?

Milling I really dont think you will be able to hold any rpm's in the cut over 9500....You will be closer to 7k so cant see the other coil helping any.........

9500 is a realistic milling RPM. I typically mill at 8500 - 9500 rpm.
Too bad they didn't set the limiter at 10,500 - 11,000. That would still be safe and give you plenty of elbow room.

You can mill a hardwood 3 foot wide at that rpm?

No hardwoods here, but in general, the wider the cut, the higher the RPM, since the psi at the kerf is less.
Max power on most milling saws is at 9000 - 10,500 rpm.

Mine is limited to 11k but I know I am no where near that. Silver maple would be the only thing here I would have a chance of running 9.5k. The 1/2 season hickory like milling bricks and that was only 22 inchs. The 30+ logs I will be working just to keep the saw from stalling. Light touch and really take my time.

On my 880 and big logs the fight is to maintaine your rpm's without stalling. (I stalled alot just starting) However You may do some smaller softwood that you hit your limit. Dont think thats what you have in mind living in Indiana!

Best advice I can give you is check you air filter often, keep a good nice steady slow pace. When you hit a knot it will stall the saw quick. Just let it idle for a few and start again. If not there lots of sanding to do!
