Seriously? Seems like an awful waste to go 8 AN feed all the way and choke it down to 6 AN (yes I know 2 6 AN's flow more than a single 8 AN).
I've found flow data that suggests for a particular pressure (unmentioned) an 8 AN of an unspecified length will flow approximately 1.77x the "Q" or flow for a 6AN line. (if you're an engineer, calm down, I don't have all the hydraulic information like material type, etc).
While the ratio would change given inputs (like pressure and pipe material and fluid type and length of piping) it serves it's purposes as a general concept of just how much flow restriction changes with diameter of tube/pipe (just as a general concept for some of you guys, if you double the diameter size of a water line you end up with 8 times the amount of flow in gpm at typical domestic water pressures).
Anyway, from what I've read Whipple claims that they're 6 AN rails will support up to 1300 hp easily, but it misses the point. At what fuel pressure and load from the pump? I suppose you could run 2000 hp off a coffee straw if you jammed enough pressure behind the pump end of the feed.
It just seems silly to plumb 8 AN feeds all the way to the rails only to choke them down to 6AN. And unless the vast majority of people are getting duped into spending extra money, there has to be some reason (i.e. market feedback) that 8 AN rails are useful or necessary for everyone else.
Does no one offer a rail that will work with the whipple without burning off mounting tabs and rewelding them?
