I was wondering how many of you actually hear your blow off valve working? When Dawn lets me drive "Waspy" I tend to drive it like I stole it (unlike Dawn) and can often hear the BOV working as I am accelerating and then changing gear etc. Also, does anyone use torque lite and could tell me what readings I should be looking at for the turbo and at what Rev range? Cheers and happy driving
Yes,but i have this one and I can hear it between 1500 and 5000 rpm. boost 0,1 --0,8 accelerating and then changing gear etc.. Workshop build in new HKS super SQV IV closed much better in performance as the original denso. SUPER SQV | BLOW OFF | PRODUCT | HKS
The standard one is a plumb back type. You probably wont hear it much if you have a standard airbox. With the roof down I can just hear mine. ITs louder with a pod filter.
I never used to notice it until after i did an oil and filter change. Maybe i hear it now because i am listening for it.
so it is with a denso..like jez77 told you. with a HKS, expensive, its really better sound.but nobody need it.
Might be worth checking you didn't knock any pipes loose when servicing. Although I often hear noises after a service might just be paranoia
It is only happening when i "off throttle" which is when it should work. Maybe the fresh oil actually allowed the turbo to spin properly and create boost. I dread to think how long the old oil had been in before we bought it and i serviced it.
