Water-Cooled or Air-Cooled Bearing Housings.
Water cooling is commonly run through OEM and motorsport turbochargers, to help prevent against heat soak to the bearing system. However, where plumbing restrictions or packaging and weight saving is key there is an option to use an air only cooled bearing housing. GBT turbos specially designed air and oil cooled bearing housing has radial air fins, giving a large surface area. Heat soak is dissipated substantially more than just basic oil-cooling alone. Drawing heat away from the oil, bearing system and rotational assembly parts reduces oil breakdown rates and improves component longevity.

Ported Compressor covers.
Generally Ported shroud compressor covers with anti-surge ports is favored, especially with larger wheel sizes, as it widens the safe operating zone within the compressor map, increases top end flow and protects against low down surge. The advantage with a non-ported compressor cover is that it is significantly quieter.

Boost Pressure Take-off and Speed Sensor Fitment
Owen Developments have designed their new compressor cover castings so that they can be drilled and tapped for boost pressure and speed sensor fitment. This gives complete flexibility to what data needs to be extracted from the turbo when in operation. Speed sensor kits and Boost pressure take-off kits can also be supplied upon request.

Oil Filter and Restrictor
Many turbochargers fail due to debris contamination in the oil feed, which can catastrophically damage the motorsport bearings used in these turbos. This newly designed oil feed union houses a stainless-steel mesh filter which will capture all potentially damaging debris and vastly increases turbo longevity. In-house testing has shown that the oil feed union will supply the bearing with an optimal amount of oil between 3-4 bar of oil pressure. When excessive oil is being supplied to the turbo as a result of higher oil pressure, a modified oil restrictor can be used. This can be inserted in to the union reduces oil flow by around 23%.

Anodizing.
The GBT units come with red anodized compressor wheel and black compressor backplate as standard. There is an option to select silver anodized compressor wheel and backplate if desired. In addition to giving the turbos excellent aesthetic appearance, the anodizing creates a protective layer on the aluminum that helps prevent oxidization and increases resistance to scratching and wear.
