Bridge specs
Okay, so im drawing out my port for my n/a. Its going to have a decent size street port on the secondaries, a small bridge for the aux. ports and the primaries will be only smoothed a little. Anyway, ive done the bridge on a junk housing and it turned out pretty nasty. So this time im going to be real careful and measure everything out to the mm. I figure i'll go up 3mm on the auxilliaries, but in order to know how far out i can go with them i need to know just how thick the bridge needs to be in order to insure that i dont snag any seals.
I ran a search on the subject and no one really gave a clear answer on how thick the bridge needs to be on the surface area of the iron. But there was a thread on how thick the material needs to be from the surface of the iron the inner surface of the runner, im not really worried about this since i wont be back-cutting it.
Thanks,
Brett

In fact, mazdaspeed7 found that his aux bridge was faster with the aux ports wired shut! Something about the greatly different port timing sharing the same runner causing everything to get upgefucked. Might work just fine if you had a separate pair of runners altogether for the aux ports. Although the easy way to do it would be to use the existing secondary runners in the upper and lower for the aux ports, blocking off the secondary ports, and routing the new manifolding to the secondaries. But then you'd have to figure out what to do with the secondary injectors, since they would now just puke at the aux ports, bad thing if they were closed.
You'd want the bridged ports to open with respect to manifold vacuum. Low vacuum = ports open.
