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.
