Wood registered around 150 kph on the speed gun as he wrapped up his first Test five-wicket haul.
Mark Wood took 5-41 in an intimidating display of speed before England finished a tumultuous second day of the third cricket Test with a 142-run lead over the West Indies.
Sixteen wickets fell Sunday, with England quickly dismissed for 277 in its first innings and then bowling out West Indies for 154. England reached 19-0 in its second innings at stumps.
England, which has already lost the three-match series 2-0, resumed on 231-4 but lost its last six wickets for 45 runs.
Ben Stokes (79) and Jos Buttler (67) added only one run in their fifth-wicket partnership of 125 before Buttler was bowled by Shannon Gabriel. Stokes was caught behind against Kemar Roach.
Opener John Campbell top-scored for West Indies with 41 before being trapped leg before wicket by Moeen Ali, who returned 4-36.
Wood registered around 150 kph on the speed gun as he wrapped up his first Test five-wicket haul.
The 29-year-old seamer's ability to hit express speeds has long been known but his previous 12 tests, the last of which came in May, included 30 wickets at a disappointing average of 41.73.
"I've had some horrible dark days with injuries and things like confidence and self-belief," Wood said. "I thought in my own mind I was an England player but I hadn't shown it," he said.
