It occurred to me that since I switched to lightweight wheels/LRR tires and increased tire pressure, I have not revisited my highway FE. Before the change when I had the larger, heavier non LRR tires at 55 PSI, I recorded 58 MPG at 55 MPH.
Today I repeated the test at similar temps. For the same 15 mile RT, I recorded 62 MPG at 55 MPH. Not bad considering that I went back to the stock springs/ride height and it was raining. Tire pressure was significantly higher than 55 PSI however.
I targeted 60 MPH on the speedo which is 56 MPH actual. The tach indicated 2400. Swapping to the CX tranny will drop those RPM's down to 1900. I'm hoping that will get me up to 65 MPG at 55 MPH and 75 MPG at 45 MPH. Only time will tell. Just need to get that tranny swapped out!
Ben,
Do you need directions to my house?
