All the Blackjacks need a max engine boost. Most of the models can only achieve ~93kph with speed tweak. This seems horribly slow for a mech that is smaller in stature compared to the Centerion which has a 275 engine cap. The Cicada which is 5 tons (40 tons) can mount drastically larger engines (340 engines).
I think that for the Cicada to have a place in the game, it needs to have a high engine cap and the Blackjack should not rival it in this regard. However, I would expect something closer to the 275 engine to be mountable.
I would happily settle for the 260 series motors. 235 series as a maximum is simply far too low for all the models other than the BJ-1X.
