Magnacharger supercharger parts and labor to install

[H2BRUTE]

Well, I've contacted at least 3 shops in S Florida and as usual I get three different stories regarding cost of the supercharger plus installation. In one of the Ultimate Hummer mags, Hummer's Gone Wild said it was about $5800 for a polished one and about a one day install. Based on the installs that some of you have either done yourself or had done, what do you feel is a fair price to pay for the supercharger (polished), labor rate per hour, and total time for the install and to get it running properly? Your help is always appreciated and invaluable..Da BRUTE
