Also, I do have a website. www.topgunspeedworks.com I have not yet placed the ACE kit on the site since I have limited inventory. That is being solved soon and should not be a problem moving forward. The website is getting an overhaul and will be much more user friendly. I will also be adding some really cool add ons to the kit and the VQ in general. Thanks, Aaron

gonna post this on here since I'm sure Seb and Topgunz are getting sick of trying to help me out with this supercharger/bov flutter. I raised the car up and had my foreman listen for the noise. He said there was air pushing out of the supercharger inlet when the noise was happening. Anyone have any ideas?
https://photos.app.goo.gl/AygMQsNj3rsx98ZZ8 edit: another video of the noise. this ones longer. https://photos.app.goo.gl/2VgrZzVosRHJuL9j9 Last edited by DUSHER; 06-06-2020 at 02:37 PM. |

Compressor surge?

According to that article isn't that what the BOV prevents (compressor surge)?
Assuming the BOV is working properly and has the correct spring for the application. My guess is that when the "fluttering" noise occurs, it's from a condition of zero boost /vacuum and the particular BOV's spring allows the valve to open and close a small, fairly rapid amount because in those conditions it's getting some sort of oscillation between tiny boost and tiny vacuum (neutral). |

I was getting fluttering when I had my qrj installed. I replaced the 1.5 psi spring with a 3 psi and it was fine after that.

As far as different BOV/PSI spring rates are concerned I thought you have to use the one the A to A kit comes with as it's designed for that setup and that changing it will affect how the whole system works properly or not. |

It is absolutely the BOV being under the right conditions to allow it to fluctuate between open and closed. When that condition is just right it is not under enough vacuum to be pegged open and the air the SC is making (which it is always making) has to escape. The valve gets pushed up by the air, the spring pushes it back down, due to not enough vacuum. This happens repeatedly and quickly giving that chopping/fluttering sound. I experimented forever with this on my initial kit back in 2014. Vacuum changes from car to car and from environments, namely altitude.
If you get flutter then try a slighlty stronger spring, or you can throw in a shim, like a really thick washer. This makes the spring stronger. Also, adding resistance to the output will help. Place a filter on it (Return style only). I bet if you bought the cover that makes the Q50 return style, it would be gone. As long as the BOV is staying open in idle and decell, and shut during boost anything goes. Maybe the 3psi spring would work better.
