Made to withstand the pressures of the Weistec 3 liter supercharger and NOS safe if I desire to spray later. Custom made CP-Carrillo rods with multiphase CARR fasteners. Crank work. Then rotational mechanic has to balance out all moving bottom end. Bearings and such replaced. New smaller bottom end parts replaced. There's also assembley cost for the bottom end. Then the top end mod's get real pricy. So over all,Grip Grip's friend is offering a good value price for a V-8 supercharger engine and transmission swap. Just for a good read,check out Hot Rod Network requiring BWE (Bruce Walker Enterprise) to prove there piston and gapless piston rings horse power gains> Childs & Albert's Zero-Gap Second Ring-Piston Ring Technology.

Wow, you're not f'ing around. A Weistec on that little car should be 9's if you were so inclined. A SL55 with stock blower and no spray is running 10.1's on MBWorld, and your XF is a few hundred pounds lighter. The only thing I hate about installing the Renntech (Kenne Belle) supercharger on my car is that it hides under the ugly intercooler and engine cover. That's not the case with the Weistec, as it's all Mad Max right in your face. I'm jelly. If I go with the M113K swap, there's a world of opportunity for modding, and the car should be easy mid to low 10's without a SC swap or spray.
