Crazy Carl BD Super B Special Turbo

This is a BD 64/71/14 turbo. Also called a super B special.

The Super B Special bridges the performance gap between the Super B turbo and the Super B twin system. Flowing an amazing 80 lbs. of air per minute (compared to 61 lbs./minute for the Super B), the Super B Special is perfect for late-model Cummins common-rail or modified 12-valve engines and can deliver enough air for 550-625 rear wheel horsepower on diesel only.
