Water cooling is a key design feature for improved durability and we recommend that if your turbo has an allowance for water cooling, hook up the water lines. Water cooling eliminates the destructive occurrence of oil coking by utilizing the Thermal Siphon Effect to reduce the Peak Heat Soak Back Temperature on the turbine side piston after shut-down. In order to get the greatest benefit from your water-cooling system, avoid undulations in the water lines to maximize the Thermal Siphon Effect.
For best results, set the orientation of the center housing to 20°. Significant damage to the turbo can occur from improper water line setups.
