This is more a matter of semantics and polish rather than an opinion on the revamped Cyclone, but while the name of its new speed update, “Hurricane Thrusters”, ties in with the unit name and its main weapon, the Typhoon Missile Pods, I can’t help but feel the name is incredibly corny, and also doesn’t make sense for a vehicle that uses half-tracks for propulsion, since a thruster is usually used for an aircraft, spacecraft or, in the StarCraft universe, a hover vehicle (e.g. the Ion Thrusters for the Vulture) rather than wheeled or tracked vehicle that uses friction against the ground and hence requires a power plant that can turn a crankshaft. Granted this might have to do with the icons that are available for re-use. With all that in mind, I would like to suggest renaming the upgrade to Axiom Turbine and change its picture to use:
Assets\Textures\btn-upgrade-terran-nova-specialordance.dds
This picture is of a glowing blue ring on what looks like an exhaust vent or maybe a bladeless turbine rather than a jet of flame. A link to it is here:

In-universe, Axiom is an arms manufacturer. The lore behind the Cyclone suggests it was developed in-house by the Terran Dominion, but it’s not a stretch of the imagination to think that their designs aren’t the most efficient, and a company who specialise in manufacturing would be able to create a more efficient power plant that can be retrofitted into existing vehicles without much additional cost.
Thoughts?
P.S. As a side-note, the icon on the Cyclone itself when it hasn’t yet been researched still has the tooltip “Research Mag-Field Accelerator at the Factory Tech Lab”, and the tooltip for the upgrade says “Increases the move speed of the Cyclone.” instead of “Increases the movement speed of the Cyclone.” (compare the tooltip for Metabolic Boost, for example)
