9 best blitz blow off valves

Blitz blow-off valves, also known as BOV (Blow-Off Valves), are a type of engine component used in automotive applications, specifically in turbocharged or supercharged engines. These valves play a crucial role in managing excess pressure generated by forced induction systems, such as turbochargers or superchargers.

Here's what you need to know about Blitz blow-off valves:

  1. Purpose: The primary function of a blow-off valve is to release the excess boost pressure that builds up in the intake manifold when the throttle is suddenly closed, such as during gear changes or when lifting off the accelerator pedal. This helps prevent damage to the turbocharger and other components in the forced induction system.

  2. Operation: When the throttle closes abruptly, the airflow to the engine decreases, causing a sudden increase in pressure in the intake manifold. The blow-off valve opens in response to this pressure spike, allowing the pressurized air to vent into the atmosphere or recirculate back into the intake system, depending on the type of valve used.

  3. Blitz: Blitz is a well-known Japanese automotive performance parts manufacturer that produces a range of aftermarket blow-off valves. They are renowned for their high-quality products and have gained popularity among enthusiasts for their performance and reliability.

  4. Types: Blitz, like many other manufacturers, offers various types of blow-off valves, including atmospheric (also known as vent-to-atmosphere) and recirculating (also known as bypass) valves. Atmospheric valves release the excess pressure into the atmosphere with a distinctive "whoosh" sound, while recirculating valves redirect the excess pressure back into the intake system to maintain a closed-loop system.

  5. Benefits: Installing a Blitz blow-off valve can help improve turbocharger longevity by reducing the risk of compressor surge (a condition where the turbo's compressor wheel stalls due to sudden pressure changes). Additionally, it can enhance the performance and sound of the vehicle by providing that characteristic blow-off valve noise.

  6. Compatibility: It's essential to ensure that the blow-off valve you choose is compatible with your specific vehicle make and model, as well as the type of forced induction system you have installed.

  7. Installation: Proper installation is critical to the effective operation of a blow-off valve. It should be installed in a location that allows it to respond quickly to changes in pressure and airflow.

  8. Tuning: In some cases, tuning of the engine management system may be required when installing a blow-off valve to ensure that the air-fuel mixture and other engine parameters remain within safe and optimal ranges.

In summary, Blitz blow-off valves are aftermarket components used in forced induction systems to release excess pressure and protect turbochargers and other components. They come in various types and are known for their quality and performance in the automotive aftermarket industry. Proper installation and compatibility are essential for their effective operation.

GReddy (11501665) Blow-Off Valve

GReddy

Based on 53 reviews Check latest price

Product description

Greddy has updated their popular blow off valve for late 2013 with a new Type FV series universal BOV. The GReddy BOV FV is a new generation of blow off valve. The unique "Floating Valve" design incorporates a revised adjustable dual spring system, while maintaining the advantages of the previous model's push valve structure and silicone diaphragm control. The improved design makes spring preload setting less dependent on the idle, while providing better response, increased valve travel, more air-flow and added resistance to premature valve lift under all conditions. Also maintained is a slimmer CNC outlet with discharge ports to draws surrounding air to amplify the blow-off sound, however this can be replaced with optional re-circulation adapters in various sizes. The BOV FV adopts the same mounting and outlet size and position as previous GReddy RZ and RS models, so retro-fitting onto existing applications is possible. All GReddy BOVs are compatible with standard GReddy Blow-off Valve flanges (flange NOT included).
