  1. The walnut blaster works well. One thing though, eventually you will have to replace the media as it will get worn. This is a very good teaching video for people who don't understand about DI's bad side. I know you watch I Do Cars, did you see his tear down of a modern diesel? Some of the intake ports were almost completely blocked. The downside to cleaning them out is the complexity of getting to the ports to clean them. You started your shop with four bare walls and you have invested heavily in equipment upgrades. Bravo! You may find that your shop is not big enough.

  2. My question is what HP are these massive trains running? And forget electric. Maybe a nuclear power plant in the future ala "Back to the Future".

  3. I have the complete Banks kit for my Cummins 12 valve. It worked wonders towing my 9,000 pound travel trailer.
