Agreed, plus it also depends on how many tapes they are writing to concurrently and the speed of those writes.
Also, if you're using automatic channel configuration, then just change your RMAN configuration to use parallelism 3 like this:
RMAN> CONFIGURE DEVICE TYPE 'SBT_TAPE' PARALLELISM 3 BACKUP TYPE TO BACKUPSET;

It depend - if your database storage can give you enough throughput to fill 8 tape streams there is a chance to reduce a time.
It's quite easy just add another channel with sbt_tape type to RMAN script.
