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
