Well, after a couple of months of trying to get my CIS working corectly...the thing got real rich at the track in May...and going through all sorts of histronics and hand wringing, I finally decided I MUST have a leak somewhere. Sure enough, the bottom seal of the SS airbox blew out on a backfire, probably right around when I last took it to the track.

So, I'm going to pull the engine, fix the airbox, tweak a few other things while the engine is out, and fit the airbox with a popoff valve, which I had sealed closed to keep the boost from escaping (he original problem which stated this thread). I have some springs which will likely work, and I will test the pressure relief function when I get the airbox sealed up again.

It still amazes me, that even with a blown up airbox, that little 3 liter makes a lot of power. If I ever get it sorted, it should be fun.
