I have a 94 LS with a rev-hard stage2, deltagate, vortech bov, msd btm, walboro in tank pump, vortech fmu 8:1, R/C 310 injectors ,Apexi AVCR. My question is when the install was complete we started it and there is what sounds like a rattle coming from the turbo, I have read about turbo flutter from the bov being too tight so i took it about 2 turns out and no change. I checked the oil return from the turbo and it is getting plently of oil. Is this normal for the first few minutes? We have only idled the car for about 3/5min. Next ? is right now I have the vacuum from the compressor going to the boost fitting on the wastegate and the vacuum from the bov going to the manifold, is this correct? and what is the vacuum setup for the avcr, it has normally open-normally closed and com what goes where? I have not convinced the bov and wastegate are working properly I reved the car to about 3/4k and no bov nor wastegate, just don't want to take it on a test run and boost to 12lbs. Thanks in advance!

 

The noise problem is solved but, could someone tell me how to hook up the vac lines for the avcr. I am using a deltagate markII wastegate.

 

you wont really hear the bov in neutral...
