First let me say that it was not and is not my intention to run a stock outlet with this much overdrive. I'm currently in the process of making a custom outlet which will more then handle the amount of volume required for that much OD.
But anyways, I am running 15%OD on a fully ported 94 blower with a stock outlet. I just got the car back on the road and have been driving it hard and doing some shake down blast to try to reveal any issues that I may have.
Well this past week up in Williamsport I was smelling "burnt" oil like there was a valve cover leak. After doing some looking it turned out not to be a vc leak but instead it was blowing some oil vapor from between the S/C and the outlet. Now the only reason that I can think that it is doing this is that with the amount of air the S/C is moving that outlet cannot handle it which is causing excessive pressure in the outlet, which has to go somewhere. So with that the excess pressure is leaking out between the outlet and the S/C.
Now I know the question is going to be asked as to what I am using to seal the outlet. Well I am using Permatex Anaerobic Sealer which is the same sealer that is used by the factory. I used this before with the previous S/C, ported 92 w/5%OD, and I didn't have any issues with it so I don't see the sealer as being an issue.
Now the only thing I have to wonder is how much power is being lost because of this bottle neck in the system?
