Record laps set in qualifying are classed as unofficial at the TT but no one would bet against the pair being well inside Michael Rutter's official 2013 lap time in Wednesday's SES TT Zero race.
McGuinness was quicker by just under four seconds to the first checkpoint at Glen Helen and was faster than Anstey in every sector, eventually recording the first sub 20 minute electric bike lap with an incredible time of 19:35.007 (115.597mph), over twenty seconds ahead of Anstey's 19:55.221 (113.642mph).

In the sidecar qualifying session, Dave Molyneux (20:16.358/111.668mph) looked to put Saturday's disappointment behind them ahead of Wednesday's Sure Sidecar 2 Race while John Holden/Andy Winkle also posted a 110+lap (110.394). Father and son outfit Ian Bell/Carl Bell (109.383) will be looking to build on their excellent fourth place in the first sidecar race while Manx outfit Karl Bennett/Lee Cain (108.462) also enjoyed another excellent lap of the course.
