How do I adjust my dual port BOV?
How to adjust a BOV?
- To Adjust the BOV, rotate the cap, this increases the spring force on the piston,
- Rotate the cap clockwise in the direction of hard as marked on the top of the lid.
- To decrease the spring force on the piston. Rotate the cap anti-clockwise in the direction of soft as marked on the top of the lid.
How does a dual port BOV work?
A dual port BOV uses a valve section that is activated by low pressures, like those encountered during idle or slow speed driving. At higher speeds and pressures, a secondary valve opens to relieve the large quantities of back pressure produced when the throttle is released.
What is Mini Cooper noise maker?
On the earlier Gen 2 Cooper S models, the factory added a ‘Noise Generator’ along the intake piping to manipulate the intake sounds from the engine. Although this may seem innocuous, it adds volume to the intake piping which means more air to compress for boost.
How do I make my BOV louder?
Vent to the Atmosphere
The easiest way to obtain a more noticeable sound is by installing a blow-off valve designed to vent directly to the atmosphere. Airflow is vented directly to the engine bay with no intake tubing or air boxes to muffle the sound, resulting in a far louder discharge.
How do you get turbo flutter with a BOV?
If you want your BOV to flutter a bit, try increasing the spring preload by turning the adjustment clockwise. It’s perfectly safe to set your BOV up to cause some low-rpm flutter, as long as it vents with a whoosh at high-rpm and boost.
What does harder and softer mean on a BOV?
Softer = less vaccum to actuate the valve; Harder = more vaccum to actuate the valve. So in essence the more boost you are running the harder the spring needs to be set at. In some BOV’s you have to just swap out the spring to a different stiffness spring to control it.
Do you need a tune for Turbosmart BOV?
A: No tune is required for this Blow Off Valve. Atmospheric releases all boost pressure into the atmosphere, and if by vent you are referring to recirculating, it will release the boost pressure back into the intake system.
Do you need a tune after installing a BOV?
A: Tuning is not required for BOV’s, so you will be just fine to bolt this right up!
Does turbo flutter damage?
Turbo Flutter is Harmless
In short, flutter is the sound of a turbocharger trying to push air. However, failing due to closed throttle. Therefore, it dramatically increases the load on the bearings of the turbo. If it occurs at higher engine loads or boost levels, it can cause premature wear to your turbo.
What makes a turbo go Stututu?
When there is vacuum (no boost) in the intake manifold relative to the rest of the intake system, the BOV opens. It’s the BOV that makes the signature turbo sound (“pssst”; “sutututu”), not the wastegate.
Can a BOV damage my engine?
The simple answer is NO! A Turbosmart BOV or BPV are designed and engineered to improve the performance of your turbocharger system and NOT damage your engine.
How can I make my BOV louder?
Install a Cold Air Intake
A side effect of this more direct airflow route, is a substantial increase in blow-off valve discharge noise, even on units fitted for factory style recirculation. Any blow-off valve vented to the atmosphere will give you a louder, more noticeable sound, but it is not without its tradeoffs.
How do I make my BOV sound?
The easiest way to obtain a more noticeable sound is by installing a blow-off valve designed to vent directly to the atmosphere. Airflow is vented directly to the engine bay with no intake tubing or air boxes to muffle the sound, resulting in a far louder discharge.

Can I run a BOV without a tune?
Can you put a BOV on a stock turbo?
Registered. Yes you can, but it actually decreases performance as the stock BPV is one of the most efficient designs out there.
What makes the Stututu sound?
Does cold air intake make turbo louder?
The sound of your car will be louder and more aggressive with a cold air intake. Instead of loudness though, a cold air intake changes the sound of your car engine. You will clearly hear the sound of air flowing into the intake – especially when you rev up the car and then release the throttle.
Is there a BOV that flutters?
If a car is making a fluttering noise when venting at high rpm and boost, then the BOV isn’t doing its job. Contrary to popular belief the noise is actually emitted from the turbo, not the BOV itself.
What makes a turbo spool louder?
What makes a turbo whistle?
What causes turbo whistle? Turbo whistle is the sound of the compressor inside the turbocharger speeding up (also known as ‘spooling up’, which is why it kicks in at the boost threshold (when the turbo starts to kick in) as you accelerate up the rev range.
