Guns, as an engine (4)

Ross

I believe the answer is:

revs

'guns as an engine' is the definition.
(I've seen this in another clue)

This is the entire clue.

(Other definitions for revs that I've seen before include "Units of engine speed (abbr)" , "Rotations of a motor, in short" .)

I've seen this clue in the Universal and The Wall Street Journal.
