I"m wondering how much horsepower the case-o-matic from a 830 comfort King can take? I seen a while back where someone but a 336 with a turbo in a early 830. I"m guessing it would be somewhere around 100 horse or more. I know this would just be a guess, but does anyone have an idea?
Thanks to any and all replies.

I'm not sure how much they can take but my grandfather farmed with a 830 case-o-matic that had a turbo. It was an early 830 low profile. He used it from the time it was new until he retired in 1973. He had the turbo installed at his Case dealership and the tractor ran at 110hp for many years with no problems. I wish I could find that tractor today.

Depends on what you are doing with it. Heat build-up will be your enemy. If you are "pulling", I don't know. If you are farming, I would think that 150HP wouldn't be out of the realm as long as you are in direct most of the time, and not building heat in converter drive.

My son posted this a couple weeks ago in a discussion about putting COM in a 930.

The COM designed for the 60 HP 830 is not as useful with more horsepower in certain situations. It is hard for me to explain but with the converter locked up and 100 hp the drawbar pull is higher than the amount you can get through the converter at stall speed. I think our charge pressure may be a little low and higher charge pressure will increase the torque the converter will transmit. (increases heat too) COM is still handy for downshifting for headland turns while keeping the PTO speed up or starting a load smoothly on the road, like a full load of manure at the end of the lane.
Also we try to be nice to the lock-up clutch by backing of the throttle as you shift into direct drive. The first time I pulled the 830 naturally aspirated I picked too high of a gear when i shifted into COM the tractor just stopped because it was under a hard pull.

Basically I don't think you will be able to pull much more with a 930 in COM as you would with an 830 in COM, but if you you want the ability to shift on the go under light load it may be useful. Once the lock up clutch is engaged in will hold a lot of power, the 830, with the turbo on, has shown 150 on the dyno and we haven't slipped the lockup clutch....yet.

Have Fun, Joel Harnish

Dad ran his turboed 830 COM for several years on 108hp. He didn't overload it all the time, but he wasn't shy on pulling it hard if he needed to. I've seen him breaking ground with a 4-bottom literally 10 to 12 inches deep several times. It would carry the front wheels from one end of the field to the other, usually 1/2 mile or more. Never had tranny problems. I want to build a 1030 "Custom King" with a NA 504 and a COM someday. I think that would be a sweet combo.
