ChoCCo Member 68 Member For: 16y 9m 29d Location: Melbourne, VIC Posted 04/11/10 09:14 AM Share Posted 04/11/10 09:14 AM Hey guys,Real brain dead one for u.. I've had rapids V2 kit on my car for a about a year now and always had been running no BOV, so I just decided to put an aftermarket one on, but it doesn't open, even on the softest setting, I put the stock one on that's been vented but cant even hear the thing over the flutter.(running 10psi btw)What my question is, could the reason that the bovs are not opening because I've hooked it up wrong? I cant for the life of me remember where the vac line goes on rapids setup coz its been blocked for so long. My boost gauge reads vac but no vac line fitted? is that normal?I've attached photos of how I have it running now, where do I run the the vac lines to?The hose underneath the bov is going to the boost sensor.So as u can tell im a fkn moron when it comes to changing little things around so as much info is appreciated!Cheers-Christian Link to comment Share on other sites More sharing options...

Remove the blue thing on the bypass valve (bov) and put that bov fitting on the black tube and run the vaccuum line from the back of the plenum to the small connection on the bov.The reason your boost guage reads vacuum is because its obviously hooked up to the intake somewhere which means when idleing or driving and not on boost it reads vacuum!

They feed in from the side and vent out the bottom. They need to see vacum to open so you need to hook up a vacum line to get it too work Link to comment Share on other sites More sharing options...

As for your second question it will make a load of difference as the vac pressure on that side of the BOV will also help to move the piston to open the BOV.

If not a tune at least a run on the dyno to confirm the afr's are alright. Link to comment Share on other sites More sharing options...
