Dunno about that one, better ask Corky.
From the reading I did, it seems that turbo'd engines like the VICS working, and SC'd engines can deal without it. Corky would probably be the best source of info on the subject. I couldn't tell much difference between the VICS working or not on my MP62'd engine.
If the butterflies are intact, then the VICS would still be controllable. The solenoid controls the opening and closing of the butterflies.
I wish you could have done some dyno testing before and after. The data would have been a goldmine.

I would really appreciate the before/after results. As I mentioned, I did some smoothing and odds and ends, but left the resonance chamber intact. I could always pull the upper off and port it out, but would rather leave it alone for now.
BTW, I dropped off the parts for you at Fedex. You'll get an email once Fedex processes it. I threw a couple extra items in there for you as I didn't need them.

We'll test his theory soon enough as the car is slated for initial dyno tuning later this week. (First benchmark at 7psi. More to follow...)

I'd rather see how Paul's gutted/polished/shorter-than-OEM-runner plentium (sp?) makes a difference over the OEM setup.

So you have two manifolds also (welded and OEM functional), and will swap them out to see if disactivating the VICS in the closed position makes a positive difference?

Sorry about the confusion.
No, I only have one manifold. I was referring to seeing how well a turbo responds to a disabled VICS...
I too am interested in seeing the results of Paul's efforts.

So trackdog racing is the company that did this 1999 manifold porting out right? That looks very clean and I would love to just ship my manifold and have them port it out. Do you guys think they would be willing to do it for me? I need to get this done soon because I'm rebuilding my motor next month. Is there anyone in SoCal would can do this for me? I'll pay you guys.
