What is a Vent-to-Atmosphere (VTA) blow-off valve?

A Vent-to-Atmosphere (VTA) blow-off valve releases excess boost pressure into the atmosphere, creating the characteristic 'psshh' sound. This is different from a recirculating valve, which sends the air back into the intake system.

What does the electronic controller do?

The electronic controller manages the pressure signal sent to the blow-off valve. This allows for more precise control over when and how much boost pressure is released, offering adjustable sensitivity and duration for fine-tuning.

Is this kit CARB approved?

No, this kit is not CARB approved and cannot be shipped to California. It is intended for off-road use or in regions where emissions compliance is not required for this type of modification.

About this part

Product Details

Turbosmart is well-known for making solid performance parts, especially for turbocharging and boost control. This kit brings together their electronic BOV controller with their RacePort 50mm Vent-to-Atmosphere (VTA) blow-off valve, giving you a complete setup for diesel or low-vacuum performance engines. It’s designed to make that distinctive blow-off valve sound while effectively releasing excess boost pressure.

The RacePort blow-off valve itself is built from billet 6000 series aluminum and features a 50mm inlet capable of flowing over 330 CFM, which is crucial for handling significant boost levels. Inside, a hi-temp proprietary silicon Nomex diaphragm and a MILSPEC hard-anodized valve guide and stem ensure durability and consistent operation even under high heat. The design is CFD-driven for optimized airflow, and it includes a unique locking collar design for positive sealing at the valve seat. You also get a quick-release V-band for easier installation and adjustment of the valve's sensitivity and duration.

The included electronic controller lets you fine-tune how the blow-off valve operates by managing the pressure signal sent to it. This allows for user-configurable spring options, giving you flexibility to match the valve's performance to your specific engine setup. This kit is a comprehensive solution for anyone looking to add or upgrade their blow-off valve system for improved performance and sound.
