In perfect conditions, it can seem like the speed upgrades aren't very useful. You should consider though that in actual conditions you will always be dropping further away than the very edge of arming distance, which means the extra speed gets your torps to target faster. The extra speed is also beneficial for hitting targets that are moving away from your drop, and as El2azer mentioned, setting up cross drops.
