Today we pushed the limits and rebuilt our Kenworth W900 racing truck in ONE DAY. We tore the C15 Caterpillar engine all the way down to a bare block, then built it back up with custom high-performance parts, a massive turbo, and everything it takes to make 1,500 horsepower. From teardown to turbocharged beast — all in a single video.
If you love Cat engines, big horsepower, and racing semis, this is the ultimate build you don’t want to miss.
