I think you'll find that's more like 58 knots.

In a 45 degree turn, the G loading is 41% higher, but it only takes 20% more speed to produce that G loading, not 41% more speed.

You're right.
G-loading would be 1.41G in a 45 degree bank but the stall speed would increase by 1.19 so that would make it 58 knots (107km/h).
