How fast can you make a hundred ton Mech go? 400XLs aren't a good engine option if you want to carry guns.
I wonder if this new Iron Cheetah will be just a replication of the existing stats or if it is... let's call it "reinterpretation".
400-rate XXL engines are actually rather efficient (ignoring any potential heat issues and how heat sinks cut to payload and space), massing 17.5 tons. Clan MASC on top of that is 4 tons and a Supercharger is 2 tons. So 23.5 tons total. For contrast, 400-rated XL is 26.5 tons.
Combining MASC and SC allow for 10 hex max movement, which is incredible for a 100-tonner.
With endo and ferro and a lot of engine heat sinks, there's something like 40 tons or so for payload, though space might be tricky.
I'm inclined to bet for original stats though.
