I agree with you but I wonder how many mule engines you would have to wear
out to find out. It seems to me that a test would have to compare a
combination of all different primary tube sizes and lengths, collector sizes
and lengths and then do the same with steps, including different size steps
and step locations. Then I think if you change anything, C I, cams, rod
length, intake, etc. etc. you would have to change some header specs to get
the very most out of it. Maybe different ones for 4200 feet above sea level,
LOL.
Just out of curiosity, does anyone know if Nascar runs step headers? They
have the time and money to test all and run whatever is best.
Several years ago I saw a video that Ford did some research on exhaust
waves and reversion. Kind of interesting but most was over my head.
Just my thoughts.
