Recently, I have been taken to task for saying that if you expect to get any sort of reasonably intelligent answer to engine tech questions, Speedtalk is the place. So to be fair, I am going to test my hypothesis out. This is a REAL question that I have had for sometime, and I cant reason it out for myself, so I have posted it on that "other" forum. In the interest of fair play, I am going to post the same question here, and see what kind of answers I get. My own guess is that this will rapidly disappear off the bottom of the page, but heres your chance guys. Here is the question as posted on Speedtalk. The race is on. This has been bugging me for sometime now, and I just cant wrap my head around it. Why does a port restricted application call for a narrower LSA? It seems counter-intuitive to me. Can anyone elaborate on this?
