Even engines with high miles can be in great condition and a candidate for adding boost. Engines that are running good and that have been maintained are typically still very safe to boost. Engineered bolt on forced induction kits such as BBM superchargers are tuned to run the correct air fuel ratios and to not detonate. So long as your engine still has good compression and does not have rod knocking sounds, you should be good to go. You should have a good tune-up and no other underlying running issues when adding a boost system. We do also recommend that you replace the oil pump and water pump on engines with over 100k or more miles.
