When I first started modifying my Veloster Turbo, the stock bypass valve was the first thing to go. It just couldn’t handle higher boost levels reliably and, let’s be honest, it didn’t give that satisfying pssh sound we all love. Finding the best blow off valve for veloster turbo means balancing performance, reliability, and that distinctive sound without triggering engine codes. This hands-on guide reviews top-rated valves for both the 1.6T (Gamma) and 2.0T (N) models, helping you decide which upgrade is worth your time and money.

MOTOKU Turbocharger Wastegate Solenoid Valve with Vacuum Line Hose Assembly for Hyundai Veloster 1.6L 2013-2017 Vacuum Control Valve
Important Note: This product is a Wastegate Solenoid, not a Blow Off Valve. While it doesn’t create the sound, it is a critical component for boost control and is often replaced by owners troubleshooting low boost issues on the 2013-2017 Veloster Turbo.
While not a BOV, this wastegate solenoid valve is absolutely vital to the performance of your turbocharger. If your Veloster 1.6L is experiencing boost fluctuation, over-boosting, or under-boosting, the factory solenoid could be failing. This replacement component ensures accurate and reliable control of the turbocharger’s wastegate actuator, directly impacting how quickly and effectively your engine builds boost pressure.
Key features that stand out:
– Compatible with Hyundai Veloster 2013-2017.
– Replaces factory part number 39400-2B040.
– Includes necessary vacuum line hose assembly.
Pros:
– Crucial for diagnosing and fixing boost control issues.
– Direct fit for 1.6L Gamma engine Velosters.
– Often necessary reliability replacement for aging components.
Cons:
– Does not produce the aesthetic turbo pssh sound.
Best for: Owners troubleshooting inconsistent boost pressure or engine codes related to turbo system performance.
Expert Opinion: It’s vital for owners seeking the best blow off valve for veloster turbo to understand that a functioning wastegate solenoid is prerequisite to proper BOV function. If boost control is erratic, replacing this solenoid may solve performance issues the BOV cannot.
Helpful Comparison Insights
Choosing the best blow off valve for veloster turbo comes down primarily to two factors: your engine year and whether you have the standard Turbo (1.6T) or the N model (2.0T).
For the standard 1.6L Veloster Turbo, you must distinguish between the early Gamma engine (2013–2017) and the newer Smartstream engine (2019+). The VTA BOVs (Products 1 & 3) are strictly for the early models, while the V1 BOVs (Products 2 & 4) fit the newer 1.6L cars. Attempting to install the wrong version will result in fitment failure.
If sound is your main priority, all the reviewed BOVs are VTA (Vent to Atmosphere), meaning they are the loudest option available, delivering maximum audible pssh. Unlike hybrid or full recirculating valves, VTA valves ensure the loudest turbo noise.
The billet aluminum construction across all the core BOV products (V1 and V2) is a massive reliability upgrade. The factory valves use plastic components that degrade and fail, often leading to slow leaks and poor boost retention. Upgrading to aluminum guarantees boost holds strong.
Finally, while the Wastegate Solenoid (Product 7) is not a BOV, it’s a common failure point that can mimic BOV issues. If your boost is inconsistent after installing a new BOV, check your solenoid.
Final Verdict: Which Veloster Turbo BOV Should You Choose?
Deciding on the right valve depends entirely on your specific model and performance goals:
For the 2013–2017 Veloster Turbo (1.6T Gamma):
The Blow Off Valve for 2013–2017 (Black or Red) is the definitive choice. It directly addresses the failure point of the stock valve and offers proven reliability up to 100 PSI, making it essential for any modified or stock car in this generation.
For the 2019+ Veloster Turbo (1.6L Smartstream):
The Blow Off Valve V1 (Black or Red) offers the best solution. It provides the same critical material upgrade (billet aluminum) and aggressive sound, ensuring perfect fitment for the refreshed engine platform.
For the Veloster N (2.0T):
The Blow Off Valve V2 (Blue or Red) is specifically required. Given the higher power output of the N model, the robust machining of the V2 ensures the valve can handle the sustained higher boost pressures without compromise.
Frequently Asked Questions About Best Blow Off Valve for Veloster Turbo
Is installing a VTA (vent to atmosphere) blow off valve safe for my Veloster Turbo engine?
For the Veloster Turbo, installing a VTA blow off valve is generally considered safe. However, because the vehicle is Mass Air Flow (MAF) sensed, venting air that the ECU has already measured can sometimes cause a momentary rich condition between shifts (especially noticeable at idle dip). Most modern aftermarket BOVs are designed to minimize this effect, and since the 1.6T engine relies heavily on the MAP sensor for boost calculation, most owners experience zero performance impact or check engine lights.
Do I need a custom tune after installing a new blow off valve?
No, installing a direct-replacement blow off valve like the ones reviewed here does not typically require a custom ECU tune. These valves use the factory vacuum reference and are designed to function within the parameters of the stock engine control unit (ECU). If you are running significantly higher boost levels than stock (due to a larger turbo or aggressive tuning), the billet aluminum construction ensures the valve can handle the pressure, but the basic functionality doesn’t change the necessary tuning.
What is the difference between a blow off valve (BOV) and a bypass valve (BPV)?
A bypass valve (BPV) is the factory component; it recirculates or vents excess boost pressure back into the turbocharger’s intake pipe, keeping the air metered by the MAF sensor. A blow off valve (BOV) vents that excess air to the atmosphere (VTA), creating the distinctive pssh sound. Functionally, they both protect the turbo from compressor surge, but the BOV prioritizes sound and eliminates the warmer air being sent back into the intake.
Will an upgraded blow off valve improve my car’s horsepower?
Installing the best blow off valve for veloster turbo does not directly increase horsepower. Its primary function is reliability and protection against compressor surge. The performance benefit comes from retaining boost more efficiently than a failing or leaking plastic factory bypass valve, particularly under high load, which ensures consistent power delivery.
How difficult is it to install a blow off valve on a Veloster Turbo?
Installation is generally straightforward for a DIY enthusiast and often takes less than an hour, depending on the model year. The reviewed BOVs are direct replacements, meaning they bolt directly into the factory location. You typically only need basic hand tools to access the factory bypass valve and secure the new aluminum unit.
If I hear “turbo flutter” after installing the BOV, is that a problem?
Turbo flutter (also known as “compressor stall”) is the sound of the compressor wheel briefly stalling when the throttle is closed and pressure isn’t vented quickly enough. While the BOVs reviewed here are designed to prevent this, if you hear flutter, it usually means the BOV spring tension might be too soft or too stiff for your vacuum levels, or the vacuum line signal is weak. A well-adjusted, high-quality BOV should prevent flutter entirely.
