APS Twin Vent back on for me after having partial throttle flutter/leak issues. I fixed it by applying hondabond around the main rubber o-ring seal, which was apparently where the BOV was leaking, and driveability is now perfect again. No flutter whatsoever. Now I just need Kevin to turn down the WGDC's, since it's holding at least 3 psi more than the OEM IX DV was when I last got tuned.

 

To answer your PM question, just go to the Synapse website, go to the BOV page, and you can get flanges to mount the Synchronic BOV to whatever mounting provision you have on your UICP.

 

partial throttle flutter/leak issues thats exactly my problem. Thanx for an advice

 

Stock VIII valve will do the trick.

 

Make sure you teflon tape the adjustment screw too. That didn't fix the problem I was having, but I think that's the most common issue that others have experienced with the APS BOV. Hondabond FTW!!!
