The original belt that came with the sn2000 kit is maxed to its tightest position. I am thinking of trying to convert to a cog setup. The crank pulley has 57 teeth and the charger pulley has 32 teeth. It looks like my trans is shifting at 5000-5100rpm during the 1-2 shift and 4900rpm during 2-3. With this setup it looks like the charger with be spinning 39.5K @5000rpm. If the rpm are brought to 5250 it looks like I would have to get a 34 crank pulley. Would the 57/32 combo be too much on a street car? The supercharger does not have a cooler. Should I be concerned if the trans slips and the supercharger overrevs? The vehicle is a t.bird with a 86 mustang ho, tci shift kit and 3:73 gears.
