Diesel-powered trucks equipped with turbochargers are prone to damaging surges and other compression related problems, but there are aftermarket solutions to this problem. And such product that addresses this is BD Diesel blow-off valve. Designed for use with Chevy and Dodge vehicles, the BD Diesel Turbo Charge valve protects stock or aftermarket turbochargers from surging. In this review, we installed one of these Turbo Guard valves in our truck and put it to the test.
- Protects stock and aftermarket turbochargers from surging and compressor wheel explosions
- Compatible for vehicles with automatic and manual transmissions
- Revolutionary new design with adjustable valve opening pressure
- Microprocessor with six different custom settings
- Available in steel and aluminum
- 1-year manufacturer warranty
Things that we liked
- The valve has a built-in microprocessor that allows you to customize up to six different settings, including valve opening pressure, activation sensitivity, and clutch cancellation. It's definitely a plus for those who like to tweak their turbochargers.
- Highly sensitive to pressure. The valve immediately detects and responds to any discrepancy in air pressure, effectively shutting down any chance of surging in your car's throttle. In addition, the truck's throttle position can also be used to trigger the blow-off valve, so there's no need for toggle and micro-switches that add extra complexity to your driving.
- The valve is made of thick, high-grade steel or aluminum, depending on the model you purchased. We do recommend getting the aluminum model as it is lighter and more resistant to corrosion than its steel counterpart.
- Comes with all the necessary components needed to install the valve. The BD Turbo Guard package contains a general application kit, the adaptor, the actual valve, and an instruction. You can practically install this device straight from the box provided that you have the necessary tools, which include a drill, crimping pliers, and a socket set.
Things that we didn't like
- Cannot be used in California. California has really strict emissions laws that also encompass those of aftermarket parts, and the Turbo Guard sadly didn't make the cut. So if you are living in the Golden State, take note that installing this blow-off valve in your vehicle might make it illegal to drive in your state.
The bottom line
The BD Diesel Turbo Guard blow-off valve effectively guards turbocharged diesel engines against damage from accidental surging. We definitely recommend this device to truck owners with turbodiesel engines.
