Just had a very informative discussion with Philip at Alpine Supercharging. The warranty they supply is not backed by Isuzu in any shape or form. Dell is Alpine superchargers own personal underwriter. They will warranty the motor only if Isuzu can prove that the damage was directly related to the supercharger. But Isuzu having no dealings with Dell or Alpine supercharging directly, does not consider them to be a factory authorized aftermarket dealer and Isuzu will void your factory warranty immediately as soon as they open the hood. You can attempt to seek help through the Magnuson-Moss Act to have warranty work done, but I can personally tell you you won't get any where with this route without an attorney, more money then it would cost to replace the origional factory motor with a crate motor, plus several years of your own personal time. To basically sum it up, the warranty is a joke. Your remaining 10year/120,000mile on applicabile 2001 model years or 5/60 on 99' and 00' models is in the trash. For some of you, like myself, who seem to have gotten the idea that the factory warranty was going to remain in effect you now have a decision to make because after the install your are on your own.
