Anyone one running a procharger on a RB?

Is anyone running a procharger or equivilent on a 440? I emailed one of the suppliers and they are damn expensive. $8500 for the charger and all to tie it together plus a custom carb, Stage 2 water injection, fuel pump, race relief valve and a boost referenced fuel pressure regulator. Anyone running a homebrewed set up? I would like any info you guys can give such as cam choices, carb choices and mods. Can the carb be modded by myself? Or is there a bunch of machine work? anything is good

Thanks
