Okay, let me give this a shot...
This first piece has always been a favorite of mine. Very virtuoso, but I don't think "breakneck," and it's a crowd pleaser. A little short though. (Gershwin/Wild I got rhythm etude)
Is Liszt something that might work? If so, Grand galop chromatique may work, as well as a whole host of other Liszt.
Next, maybe major key chopin etudes? Or are they not quite as crowd pleasing as you want...
Perhaps the third movement of prok's 7th sonata? I don't know if you'd call it major enough though. If you want 1900s era classical music, check out the fourth movement of Liebermann's gargoyles, the first movement of petrushka

.
Or, what about those transcriptions of the horowitz/cziffra. Stars and stripes, carmen fantasy, etc.
This last one, is super hard, but why not...

I threw all kinds of stuff out there. If you let us know which type of piece you like, I can give more suggestions. Let me know what you think.
