My brother and I have owned 4 Vipers between us, and DC Performance is the ONLY place we will allow to touch our cars. I have gotten to know each and every member of the staff personally over the last two years, they are a class act. You can trust them to take care of you. $2000 for a supercharger install is very fair, the install labor alone is about eight hours or more. On top of that, they will do an inspection of your motor, and theres a LOT of tuning time that needs to go with a supercharger. Its not a simple blot-on. You will not find a better Viper tech than Dan Cragin. He has been involved with the Viper since its inception in 92. You are LUCKY to live in LA and have one of the best Viper techs in the country nearby. Dont take my word for it, look trough the threads and you will see what great work they do and how knowlegable Dan is. No one in the LA area has done more supercharger installs than DC Performance. Dont make the mistake of going somewhere else (God knows if theyve ever touched a Viper before) to save a few bucks. You will regret it.
