Ive noticed over the past few months that about once every say 2 weeks instead of my BOV going off I get massive amounts of flutter, I have an aftermarket Apexi BOV and usually it goes off all the time and I get next to no flutter but on some occasions for about an hour or so it wont go off and I just get massive flutter, the car still runs the exact same performance wise when this happens but I just wanted to know whats going on?

I also have a pod filter and front mount if that contributes to this at all, turbo is stock with 14psi.

Cheers guys.

Your bov is sticking shut or something is jamming it from opening, so instead of it letting the air out its causing it to go back through the turbo and out the intake causing a flutter noise.

This is the noise you would hear if you had no bov at all.

      Thanks @Duncan Ride height is fine. I think it's almost stock tbh. Happy to share a pic. I don't actually have a regular mechanic as haven't lived in Sydney too long. Could you or anyone recommend any shops in Sydney?

      You just need a different blue slip shop (preferably one you regularly use as a mechanic), and make sure the coil overs are as close as possible to standard height

      Ethanol Content Sensor - Always at 11%?

      By Duncan · Posted

      yeah the sugar refining companies were pushing for the same in Oz originally, all fuels were going to have 10% ethanol to make them "cheaper" (noting, that the loss in l/100 might be greater than the decrease in price). I guess they won that fight in Canadia

      Another "where do these lines and plugs go" RB25DET question

      By thatjawncrazy · Posted

      GTSboy, thank you again. i’ve been reading all the other SAU RB25 vacuum line threads and you have the utmost patience for people asking “where do my vacuum lines go”. it’s appreciated. i did also enlist a few other RB guys local to me.  i would like to run 5 to 4. turbo pressure side to wastegate actuator. i would like to run 3 to 1. power steering air valve line to intercooler outlet. (this is how it was previously). i was told 2 is the bleed port for the boost solenoid - which i’m not running - so should be capped.   anyone see any problems with that?

      Ethanol Content Sensor - Always at 11%?

      By Kinkstaah · Posted

      So yes. All of them. Something like 98% of all fuel in the USA has 10% ethanol: https://afdc.energy.gov/fuels/ethanol-fuel-basics It's labelled as like, AKI, 87, 91, 93 with an E10 or E5 or E15 label on the pump. At a certain point, it's not just "E10" instead of 91. It is 91, 95, 98, and all of them have 10% Ethanol in them. You can also get E85 and E30 which is why you do see some people rolling around with E30 tunes in them.
