There are several problems with the blower mod. First is that the ZF transmission is pushed to the limit with the NA V8, so you would need to change the transmission, probably to the XKR Merc. unit. Then you have to change the programing of the ECU and TCU. I suspect some one has replaced the NA engine/ trans/ electronics with a XKR and a search will tell you if that is feasible, but like Racediagnostics said, it will be far more expensive than selling the XK8 and buying a XKR.
Before you ask, those who have invested in a after market chip upgrade have been disappointed.

One of the forum members from Poland installed a supercharger on a NA engine about a year or two ago. I remember reading that the NA engine is higher compression than the super charged version and the pistons on the NA are flat topped where the Supercharged are "curved in" thus less compression. I agree it's easier to sell the XK8 and buy a XKR.
