I’ve improved again my refurbishment service. I’ve changed ultrasonic cleaning to glass bead blasting on the compressor wheel. Ultrasonic cleaning remained for internal parts. Witht this method all of the contamination could be removed and also the micro scratches and damages on the wheel. After the cleaning it’s re-balanced for a better value than stock. Your compressor wheel will look better as new. 🙂
* It’s not a before-after picture. The top one is a damaged compressor wheel, the bottom one is a refurbished compressor wheel, just for comparison. The top one is irreparable.
