They moved to within four points of the southern track with two matches in hand.
Hans Andersen won three races for Ipswich but the rampant Fonestyle UK Aces provided the other 12 heat winners.
They also took maximum points from nine races but, in view of the huge margin, there was some thrilling racing with the home side's greater track knowledge usually decisive.
Stockport youngster James Wright defied an arm injury suffered in a heavy crash at Workington on Saturday to score two points on his Aces debut. Aces team boss Ian Thomas said: "There were some excellent races with six passes in heat 10 alone.
"The value of such a big win is that it puts us in good heart for a hectic programme and means we should get the aggregate bonus point at Ipswich barring a disaster."
Wright, 19, got off to a flyer with a great start to heat two alongside teammate Simon Stead. He had to fight off a determined challenge from former Ace Kevin Doolan but held him off to follow Stead home for full points and give the home side a lead that they never lost.
Wright failed to score in his next two rides but it was still a valuable learning curve for him. He was partnered with world champion Jason Crump in heat seven and said afterwards: "The last time I was in a race with him was two years ago but on that occasion he was on one straight and I was on another."
Joe Screen and Jason Lyons took another maximum in the third heat to establish a stranglehold on the meeting which they never lost. The Aces piled on another maximum in a thrilling sixth heat when Kenneth Bjerre and Andy Smith overtook early leader Piotr Protasiewicz to establish a 25-14 advantage.
Smith showed his passing abilities again in the eighth as the home side rattled in another maximum, a feat repeated by Lyons and Screen in the next to make it 38-19.
The home side really had their tails up now and it was only a matter of how big the winning margin would be.
BELLE VUE: J Crump 13 + 1 bonus, K Bjerre 12 +1, S Stead 12 + 1, J Screen 9 + 2, J Lyons 9 + 2, A Smith 7 + 4, J Wright 2 + 1
IPSWICH: H Andersen 14, K Doolan 5, C Louis 3, P Protaziewicz 3, R Miskowiak 2 + 1, K Jansson 2 + 1, K Baron 0
