From my experience what I notice after installation:
- Turbo noise and blow off sound is more noticeable
- Gear change is slighty faster
- Loss of power in lower rpms
- It takes time to adjust pipe on intercooler, it leaks oftenly
Had this stupid thing in my first Roadster. Glad I had the far more likeable stock chirping noise in my 2nd one back. One advantage of the blow off valve might be longer turbo longevity. One definitive disadvantage is that it's just not legal if it breathes into free air.
I think something is wrong, the turbo flutter should be with no blow of valve, the bov should make psssss sound and relief the pressure befor the trottle body when you let of the gas pedal.
Depends what setup you have, original or silicone pipes, original or open air filter, remap etc.
A little bit of turbo flutter is right
@@SmartRaceryes, it's true
@@SmartRacer the sound you have is that i have on my rodie with silicone pipes and no BOV , just check if the BOV lifts and relese the intake pressure when you let go of the gas pedal.
how do you explain the loss in performance, since the BOV lets the turbo spin more freely between shifts, thus keeping boost more constant?
i'd like to know that too
Lower RPMs and it takes effort to place new pipe on intercooler (likely to leak), gear change is defently improved
@@SmartRacer ok got it, when in lower rpms the engine runs in a vacuum like a naturally aspirated car until the turbo sets in and gives it overpressure (boost) maybe it has something to the with the fuel pressure regulator
Good job, I heard a bit of turbo flutter, the valve is fully open at max boost?
Correct, I forgot to put camera in engine bay to film how it opens
@@SmartRacer if you want, can you make a video for the valve on work?
It is already down, ready for sale
@@SmartRacer why? You don't like the bov?
Can you please help me?
I changed the actuator and now still 3 Bars Are showing in the Display. I Tried it also with reseting the clutch with delphi and nothing worked …
Im really frustrated please someone help me
Check fuses as well
@@SmartRacer which one? I checked all fuses and they all Look fine
@@DuTyPLay3r have You tried to reset the gear box selector with delphi?
So, after all, unique pro(s) is better overall sound?😂
And slightly faster gear shift
@@SmartRacer if you run 1.5 bar or more, the bov really save the turbo and throttle
Hey the acceleration has not improved?
I don't think so
One of the worst mods I ever did, removed it after a few weeks, leaked loads and the spring didn't match the tune I have on the car so ran poorly
That's your fault then. For tuned engines you can buy extra springs on their site to fit with the blow off valve depending on how much boost you generate.
Did the same, other than noise and slighly faster gear change, no other benefits
@@KiilashChieftain exactly what I did and it still made the car not as fun to drive, waste of money
I also worried that it basically leans on the engine ECU, not a good idea in my view.
Pozdrav, kako te mogu nesto pitati?
Pozdrav, može instagram ili facebook
mine sounds like that without a blow off
overall unnecessary weight 🤔🤔
I agree
