There is a video out there on youtube of a 4 door CTS-V with a upper/ lower supercharger pulley, 125 shot of nitrous and the car flat out moves, beating supercharged Vette's and Vipers. Problem is the owner knows that he is on borrowed time and already has started saving for a built engine, but that's only gonna lead to other broken parts.... but care's when you have the bank roll to afford a modded CTS-V.
Definitely worth watching to see the awesome potential of a boosted and sprayed LSA.
I'd love to post a link to the vid but dont want to risk getting my account suspended so just google it.
