So, you currently have a 12/41 (0.293 ratio) and want to go to a 14/37 (.378 ratio). If you're getting 66mph currently, you're new maximum will be 85mph (66*[.378/.293]) assuming you still have enough power to hit the rev limiter. You may be surprised at how quickly the power goes away. After all, wind resistance goes up by the square of your speed. You also asked about a 12/37 ratio, it would get you to 73mph.
