The pilot reported that during the takeoff roll, the engine turbocharger failed.

The technician determined the steel strip for the induction alternate air door magnet (P/N 1250839-21) wedged into the turbocharger inlet blades. All the leading edges of the turbocharger inlet blades were damaged. The submitter believed that due to dissimilar metal corrosion between the steel strip and the aluminum attachment rivets, the steel strip separated and was drawn into the turbocharger inlet.
