Superchargers

is 130000 miles on a truck, too many miles to put a charger on?

Not if your goal is to blow it apart…

A supercharger requires a good, stout bottom end to be fairly reliable. A well-worn engine may give you nothing but expensive headaches if you force-induct it. Most stock engines can handle mild boost, up to 4-5 psi boost. This will give you maybe a 15% improvement in horsepower, with free flowing intake and exhaust upgrades.
