Shane Byrne set Snetterton alight when he raced to victory in both Superbike races to move to within seven points of the top of the British championship standings.
In race one he made his move for the lead on lap five and was never troubled after, but behind him Australian Josh Brookes worked hard on the Anvil TAG Yamaha to come through to second. Honda Racing's Jason O'Halloran was third.
Brookes set the pace in race two, with Ellison and Byrne in line astern for 10 of the 16-lap race distance. Brookes started to ease away and Byrne made his move to pass the luckless Yamaha rider, who crashed out two laps later, and set about closing down the leader. The current champion showed why he has five British titles by setting a new lap record as he overhauled Brookes to win his 80th British Superbike race and close in on a sixth domestic crown.
'It seems to have taken a while to get to there – I've been in the 70s for a while,' he said. 'It's been a great weekend and getting the podium points was good for the championship so overall I'm over the moon.'
Series leader arriving at Snetterton, Jake Dixon, on the RAF Regular & Reserves Kawasaki, crashed out of the morning warm-up but took a sixth and fourth to move into the top six in the standings.
Danny Buchan, riding Norwich-based Morello Racing's Kawasaki, tasted the victors' champagne in the National Superstock 1000cc class to extend his advantage at the head of points table. The 24-year-old had settled for a safe third until the closing stages when his tyre management allowed him to catch and pass Mason Law, before leader Richard Cooper ran short of fuel with one and half laps to go, gifting Buchan an unexpected 25-point bonus.
Ryan Vickers from Thetford had probably the best ride of his fledgling career until halfway round the last lap. The 18-year-old was fighting for second in the Superstock 600cc class when he caught the back of Tim Neave's Kawasaki and crashed out within touching distance of his first podium finish on the national stage.
Norwich's Grant Newstead fared better on his new Tinkler's Yamaha to finish 13th after in a lower leaderboard scrap.
