Michael Dunlop was a man on a mission as the 11-time Isle of Man TT winner topped the Superbike charts with an electric 132mph lap on the Hawk Racing BMW on Thursday.

The 27-year-old set the first 131mph lap of practice week on Wednesday but set the bar higher yet again, going clear on the time sheets with a red-hot speed of 132.365mph (17m 06.164s) on his final lap as the session was flagged off, more than five seconds quicker than Tyco BMW's Ian Hutchinson.

Dunlop made it a Thursday double as he unofficially smashed his 2013 Superstock lap record with a speed of 131.336mph (17m 14.206s) on his MD Racing BMW.

He opted to go out first on his Superstock machine and after a steady opening lap of 125mph, Dunlop produced something special to break into the 131mph bracket on his 'stocker.

Hutchinson went straight out on his Superbike and incredibly lapped at 131.661mph from a standing start to throw down his claim for Superbike honours in Saturday's opening race.

The Bingley Bullet was slightly slower on his flying lap at 131.111mph, while Honda Racing's John McGuinness broke into the 131mph bracket with a lap of 131.116mph.

The Morecambe rider was followed by team-mate Conor Cummins (129.986mph) while Dean Harrison was right in the mix again on the Silicone Engineering Kawasaki, lapping at 129.9678mph from a standing start on the ZX-10R.

James Hillier - who finished on the rostrum in the Superbike and Senior races last year - rounded out the top six in Thursday's times with a speed of 128.55mph on the Quattro Plant Muc-Off Kawasaki.

He was tailed by Northern Ireland's Lee Johnston on the East Coast/Burdens BMW (128.342mph) and Michael Rutter (Bathams SMT BMW), who lapped at 128.340mph.

Kiwi Bruce Anstey came off at Keppel Gate after a couple of laps on the Honda RC213V-S, but was reported to be up and walking.

It was a pivotal night for Norton as Australian rider David Johnson set the fastest ever speed on the SG5 machine with an impressive 128.323mph lap from a standing start.

William Dunlop also impressed on his new Yamaha R1, clocking 128mph flat after only riding the bike for the first time on Monday.

In the Supersport class, Lee Johnston led the way on the East Coast Triumph at 124.838mph from Hutchinson on Keith Flint's Came BPT Yamaha (124.223mph) and McGuinness (Jackson Honda), who managed 123.478mph.

Manxman Cummins was next on the Valvoline Padgetts Honda (123.371mph) ahead of William Dunlop on the IC Racing Caffrey Yamaha (123.134mph). Michael Dunlop was sixth quickest on his MD Racing Yamaha (122.176mph).

In the Lightweight class, Michael Rutter grabbed the fastest time on Ryan Farquhar's SGS KMR Kawasaki with a hot lap of 118.054mph to lead Italy's Stefano Bonetti (Paton S1), who clocked 116.220mph and Danny Webb, also riding an SGS KMR Kawasaki (116.140mph).

Last year's winner Ivan Lintin was fourth fastest on the Devitt RC Express Kawasaki at 115.909mph.
