Extreme Modification and Customization

Columbus Diesel uses the very best turbo components from the industry and modify them to meet the needs of competitive pullers. In many cases where there is no suitable part to modify Columbus Diesel will design special tooling and/or patterns to make what's needed for max all-out performance. Shown below are some of the processes that Columbus uses to perfect their products before assembly and completion.

Turbocharger Housing machining

Customization and Modification

The photo to the left illustrates a pro-stock turbine housing off of a Holset model HC5A turbo being machined and sleeved to accept a larger turbine wheel and a 6 inch outlet pipe.

Compressor Wheel being machined

The photo to the left illustrates a compressor wheel being machined to a 3-inch inducer to meet the criteria in the super farm class.

Pinning Nut to Comp Wheel

The photo to the left illustrates the process of pinning the compressor nut to the compressor wheel to keep the wheel from spinning on the shaft.

Turbocharger Timing

Shown at left is a Pro-stock class CHRA (Center housing & rotating Assembly) being balanced as an assembly. This billet wheel has a 5-inch inducer. Note the aluminum sleeve over the turbine wheel, the assembly is spun using air.

Comp Cover being machined

Shown at left a compressor cover designed by Columbus Diesel Supply is being machined for a larger compressor wheel.

Turbocharger Side View

Illustrated to the left is a compressor side view of a pro-stock turbo with a 5-inch inducer. Note the size difference to a compressor cover off an automotive turbo in the lower left corner.

Torqued Rotor

Shown to the left is a rotor group stacked-up and torqued, then balanced before assembling into the bearing housing.
