H,

This varies with the Tesla coil.  At a low breakrate, the voltage 
is higher for a given sparklength.  The spark length grows with
higher repetition rates even with a fixed output voltage.  Other factors
affect this also.  It is not a fixed figure.  A small coil may give 
200kV before the spark breaks out (depending on radius of 
curvature of teh topload) and this may drop to 100kV
after breakout.  A large coil may give 4 times those voltages
perhaps.

Spark length depends more on input power than on voltage.
