Top Fuel engines need that much timing advance because of the fuel, not the
rpm.  Nitromethane burns much slower than gasoline, so the timing needs to be
advanced more to maximize power.  My street bike revs to 14,000 rpm and full
advance is only at 43 degrees and it uses standard supreme pump gas.
I have no
idea what F1 uses for fuel.

And...how much ignition advance do they run at 20k to help
the flame 
front stay up with the piston speed???? Top Fuel engines run as
much 
as 65 degrees to enable 9000 RPM. It's not just VE.
