What is the difference between a wastegate and a blow off valve?
Wastegates and Blow Off Valves are both designed to vent air, however, they are engineered for two different types of air flow. Turbo wastegates are placed on the exhaust gas side of a turbo system and are used to control turbo speed. Turbo blow Off Valves are placed on the boost side of the turbo system and are used to vent boost in the intake tube once you let off the gas pedal, to avoid damaging the turbo.

11 Point Turbo System Checklist
The turbo system in your car should be monitored to insure that every aspect is functioning properly to give you trouble-free performance.
Turbocharger Oil Leakage – Troubleshooting
A properly installed turbo should NOT leak oil. There are, however, instances where oil leaks occur. Here are the most common causes, depending on the location of the leak.
How To Size Charge Air Tubing
The duct diameter should be sized with the capability to flow approximately 200 - 300 ft/sec. Selecting a flow diameter less than the calculated value results in the flow pressure dropping due to the restricted flow area.
Turbocharger Water Cooling – Thermal Siphoning
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.
Turbocharger Oil Drainage
In general, the larger the oil drain, the better. However, a -10AN is typically sufficient for proper oil drainage
