Charles,
I think that among other things ... the 39mm holes make a big
difference. Also .. it sounds like they spent a lot of dyno time to
optimize the tune. 40 dyno runs are probably equivalent to a lifetime
of us looking at plugs ... making an adjustment and taking a test
ride. However, the less restrictive bore of the flatslide and the
larger diameter bore of these particular flatslides are I'm sure the
biggest factor in seeing such a gain ..... plus I am sure he is adding
their own manifolds and I would be surprised if they are as rough as
the stockers. Hmmmmmmm .. has to be some more there with a little head
work ...

I haven't a clue how much you can squeeze out of a standard
atmospheric motor , but as a rough guess maybe 5-7 xtra HP with the
Stage 7(not forgetting suction and exhausts that have to be replaced
or heavily modified). With the standard set-up you have the benefit of
having two 35 mm carbs feed each cylinder (same as with Stage 7, but
in this case sacrificing the mid & low end for the 5 HP up at the
top), so I can't really see how you can pull 20 RWHP more with a set
of flatslides. The velocity stacks in the VGAS cannot make that
difference and mind you, I would not dare ride my bike without
filters. As far as I understood in the very concise explanation UFO
makes about this system, they seem to retain some kind of V-boost. Can
some one explain to me how they do it?
I did notice a big dip in the power curve shown around the 6000 rpm
with this set-up
