With the MP2 5 th gear the ratio is .605 What RPM is that at 60 MPH ?
What if you were to get a custom gear ratio cut that would give a .510
final gear ratio. Which would be another 20% taller. What would that do for the miles per gallon do you think?
I talked to a machine shop and it would be expensive to do just one but most of the cost is for setup so it might be affordable if they made 10 sets. When I look at how much time some of the modifications take it might be worth it for me to go that route.
