Harvey, I'm not understanding the benefit of having the 3 pipes run into the expansion chamber without the use of a collector. And please don't get me wrong, I'm not questioning your knowledge. In fact I'm certain that you know more about the voodoo of engine tuning than I do, that's why I ask. But from what I have read from David Vizard, power is made in the collector. He even says that equal length primaries are not as important as a correctly tuned collector. Is the difference in the type of engine? Vizard generally writes about old V8's. As you explained in your camshaft thread, there are differences in what our engines like and what those like. Is this another one of those instances?
