Easy answers first will update the others later today;
Did you modify the charger snout to shorten it (where the pulley mounts)? No the snout is standard length for the unit that i have (see details below) Is the charger an Eaton M112 unit? Sort of yes, it is the Jaguar/Land Rover version of the M112, fundamentally they are the same just I believe it is the back of the unit where the air enters that is a bit different, and the mounting brackets on top (bottom on mine) that are different. Did you have a pulley machined for it, or was it the correct offset/number of ribs? No this is standard for the Jaguar version. If so do you have the stock crank pulley in place or a different diameter one for your desired boost level? We calaculated on the basis of the maximum rpm of the supercharger rather the desired boost pressure, in an ideal world the pulley would be a bit bigger to help reduce the amount of heat generated but at this ratio it is safe and works well, it could do with being a bit lower on the boost pressure maps to be more efficient. Having looked online before it was easy enough to get a smaller pulley as they are readily available as tuning modifications but I think I'd be the only person trying to fit a bigger one
