I've been pulling a 570 Super for years and have a few power Questions for anyone with knowledge of these tractors.It has the stock 339ci Hercules Diesel which I've overhauled and it runs at 2000 rpm's(no load)and the govenor seems to work real well under load.The pump and injectors where also rebuilt.It starts and runs great and makes 80 hp on the dyno.I've turned the pump up to the point where power reaches 80 hp.Any further beyond this point and power starts to fall off below 80 hp due to too much fuel.I believe I've done all I can with this simple adjustment.It does blow lots of black smoke under full load at this setting,sometimes even a little fire under extreme conditions.Is there anything else I should try such as timing changes or bigger injectors?I've heard that adding a electric fuel pump to supply the injection pump helps but since I can get too much fuel already,I question if it will help me.Since I'd like to move up to the "Enhanced tractor"class I'd even consider adding a turbo since the rules allow if anyone has any Ideas what would be a good choice.I am a machinist so fab work isn't a road block.Even ten more hp would be good but 20-40+ would be great.Thanks for any suggestions.
