Horsepower increase

[bcrosehill]

I have a 3321 Zetor . How much can the horsepower be increased and not cause any damage to the engine? I would like to have more power when I am in high gear traveling on the road. The mechanic at my dealer said it could be turned up to 50 hp and not cause any problem at all. More smoke or using more fuel are not a concern.

60 crankshaft horsepower will give a bit of grey smoke. Ask Markku for adjustment details...

Im not Markku (or actually I'm, my another name is Markku) but I answer.

Horsepower increasement is easily done by adjusting the injection pump. There is a motorpal row-pump and you must open the rear cover of pump. Then unscrew toppest bolt (with 10 mm wrench) and turn screw in 1-2 rounds.
