Paul, Has anyone tried a flattened tube (oval) with the flatted portion horizontal to save space?
For fixed tubes folded over the top. It could could cut the height down by 1/3 without hurting the
performance. Bill Jepson

I am not so sure it would not hurt the performance. I don't really know but
unless you keep the area constant you could cause a wave reflection. Kind of like VSWR
in a wave guide if you happen to be familiar with microwaves. Also the ratio
of surface area to cross-sectional area is less favorable.

Something I would want to test on a dyno.

Keeping the area constant would require castings. Possible of course but
more expensive than tubing. You might buy an inch of clearance at great 
expense.

BTW is it OK to publish your intake system?
