Knew a fellow that had a turbo from an '86 Thunderbird on a John Deere A. Worked OK according to him...
Should not be that hard to fab up an exhaust connection to the turbo and flex hose to the carb... Nothing else to do when its this cold... Have fun!

The carb has to be on th suction side of the turbo. Presurizing the carb will not work.

well lets see , first you are going to need a manifold or some adapter to the current one , second ,you are going to decide blow thru or suck thru on the carb,I would suggest as some one else did , on suck thru.Third I would suggest a bigger carburetor or fuel injection,their is a company that sells kits to DIY'ers,just can't recall their name. fourth would be adapting your v-belts to a serpintine belt to drive the Supercharger, and lastly, as I see it would be adjusting the blower speed (belt Pully sizes) to provide optimum boost at around 2000 rpm,or whatever speed your governer starts kicking in. I don't belive that particular super charger in stock form and drive ratio provides much more than 1-2 lbs boost at tractor speeds(rpm) and you could probably push 10+ Lbs (over drive the supercharger,big pully on the crank, small pully on the super charger)if you haven't already raised the compression on the tractor, and using a 90 octane gas, NOT RACE GAS.you might also wan't to look at cam selection after you get a system set up, and are looking to tune it up a little more.Some forseeable problems, Over heating, cylinder head sealing problems,Ignition system not strong enough ( higer cylinder pressures require more spark), crankshaft strength,and connecting rod strength. If you are looking for a overall reference on supercharging I would recomend getting some books that deal in automotive super charging I have one here " A do-it yourself guide to street superchrging" by Pat Ganahl, on S-A design Books. they will provide you with the basic principals and troubleshooting guidance you will need thru a project like that. Good Luck Shawn.
