Paul, you probably figured this already but when I modeled the VAM 
originally I wanted the point of max restriction slightly ahead of 
the exit of the cold pipe. When I reviewed the jpegs I sent this 
wasn't obvious. This area was supposed to be near the turn into 
the tailpipe. Your comment on extending the pipe would acheve the 
same ends. I made a note on the original and have included it 
for ref. Thanks, Bill Jepson
